The improbable William Laurence

Friday, October 30th, 2015

The most recent episode of Manhattan features the arrival of a character based on one of my favorite real-life Manhattan Project participants: William L. Laurence, the "embedded" newspaperman on the project. The character on the show, "Lorentzen," appears in a somewhat different way than the real-life Laurence does, showing up on the doorstep of Los Alamos having ferreted out something of the work that was taking place. That isn't how Laurence came to the project, but it is only a mild extrapolation from the case of Jack Raper, a Cleveland journalist who did "discover" that there was a secret laboratory in the desert in 1943, and was responsible for one of the worst leaks of the atomic bomb effort.

William Laurence, however, was solicited. And he was the only journalist so solicited, invited in to serve as something of a cross between a journalist, public relations expert, and propagandist. (When a character on the show hisses to Lorentzen that they "don't give Pulitzers for propaganda," she is, as the show's writers all know, incorrect — the real-life Laurence did receive a Pulitzer for his reporting on the Nagasaki bombing, and it was a form of propaganda, to be sure.)

William Leonard Laurence was born Leib Wolf Siew, in Russian Lithuania. In 1956 he gave an interview to the Oral History Research Office at Columbia University, and, well, I'm just going to let him tell his own "origin story," because there's no way I could capture his "flavor" any better than his own words do:

I was born in Lithuania, in a very small village. You know Lithuania was one of the strange never-never-lands, you might say, in a certain culture, because it was there that the Jewish intellectual, the Hebraic scholarly centers, were gradually concentrated.. …

The Lithuanian villages were out of space and time, because you know, a life there, in the ghetto, you might say — because that was the only place where the Russianized government permitted Jews to live — they lived there in the 19th century when I was born and the early part of the 20th century in a way that might have been the 15th century, the 16th century. It made no difference. They wore the same type of clothing. They lived the same kind of life, because it was the same culture, you know.1

You get the picture — the man liked to paint rather elaborate pictures with his words, no stranger to invocation ancient mysticism or cliché. Following the 1905 Russian Revolution, young Leib Siew was smuggled out of the country by his mother, in a pickle barrel, and eventually made his way to the United States. There he refashioned himself as William Laurence, and began an entirely improbable career as one of the first science journalists in the United States.2

The story that brought Laurence to Groves' attention —

The story that brought Laurence to Groves' attention — "The Atom Gives Up," Saturday Evening Post, September 1940.

Laurence learned about fission in February 1939. His wife (Florence Laurence — I'm not making this up) remembered that they were walking along Sutton Place in Manhattan, towards the Queensboro Bridge, with their dachshund (named Einstein — again, not making this up), and her husband, Bill, had just come from a meeting of the American Physical Society at Columbia University, where Bohr and Fermi had spoken on fission. In her memory, Bill Laurence had "understood" the implications immediately. A fan of science fiction and a practitioner of scientific hype, he was perhaps uniquely qualified for immediately extrapolating long-term consequences. "We came home I deep gloom," she later wrote, "The atom had come to live with us from that night on."3

Laurence's beat on the New York Times gave him an opportunity to write about fission fairly often. He was hooked on the idea, taking the old clichés from the earlier, radium-based nuclear age (a thimble of water containing the energy to move a cruise ship across the ocean, etc.) and adapting them to this new possibility. He wasn't the only reporter to do so, but the Times gave him a lot of reach, as did his writing gigs for The Saturday Evening Post.

In early 1945, one of the preoccupations with the question of the bomb's future use was what kind of information would be released afterwards. Those on the Project called this the problem of "Publicity." Groves himself seems to have had the idea that Laurence might be a useful resource to tap. He had seen his articles, he knew his style, and he knew he was already fairly scientifically literate. That spring, Groves personally went to the offices of the New York Times to feel Laurence out for the possibility of working with the Army. Laurence said he would, but only if he got to have the whole story. Groves agreed. Laurence began almost immediately.

Laurence's first job was to help with the writing of draft press releases. They were already planning to drop the bomb, and they wanted to make sure they had a "publicity" blitz (as they called it) in place to advertise to the Japanese people, and the world, what it was that they had created. Laurence's first job was to give it a shot at a statement that might be read by Truman after the first attack. His draft had that Laurence feel:

This greatest of all weapons, developed by American genius, ingenuity, courage   initiative and farsightedness on scale never even remotely matched before, will, no doubt, shorten the war by months, or possibly even years. It will thus save many precious American lives and treasure. … The tremendous concentrated power contained in the new weapon also has enormous possibilities as the greatest source of cosmic power ever to be tapped by man, utilizing the unbelievable quantities of energy locked up within the atoms of the material universe. … We are now entering into the greatest age of all — the Age of Atomic Power, or Atomics.4

And so on… for seventeen pages. This kind of hyperbolic approach was not to the liking of the others on the project. James Conant, the President of Harvard, remarked that it was "much too detailed, too phony, and highly exaggerated in many places." Fortunately, Conant wrote, "there is no danger it will be used in any such form." The Secretary of War had called upon an old friend to write the Truman press release: the Vice President of Marketing for AT&T, and father of American corporate public relations, Arthur W. Page. Page's work is ultimately what Truman did have issued in his name after the bombing of Hiroshima.

Which isn't to say Laurence wasn't otherwise useful. He wrote draft disinformation statements to be released after the Trinity atomic test, claiming it was an ammunition depot exploding. He wrote dozens of news stories that were distributed freely to the press in the days after the Hiroshima and Nagasaki bombings, explaining how the bomb worked (in basic terms), explaining how the project was organized, and telling all sorts of other side-stories that Laurence and Groves thought would satiate the demands of the American press corps — and keep them from snooping around too much on this story-of-stories.

The stories were given to the press without an author listed, and each newspaper was encouraged to put their own byline on it, making the reporting on the bomb look far more varied than it was. Source: National Archives and Records Administration, Manhattan Project files.

Many of the Laurence stories, in the end, were highly edited. Laurence just couldn't restrain himself or his writing. He couldn't talk about Hanford Site — he had to call it "Atomland-on-Mars." He couldn't just write about the bomb that had been created — he had to talk about how the next stop would be conquering the solar system. A fleet of Army lawyers reviewed all of Laurence's contributions before they were released, and the archives are full of Laurence stories that were deeply slashed and thus rendered far more sober.

Laurence was at Trinity, and was on an observation plane flying along for the Nagasaki bombing. You can sometimes see him skulking in the back of photographs from the time: short, with a somewhat disproportioned body, ill-fitting suit, and terrible tie choices.

Today Laurence is a controversial figure in some quarters. He would win a Pulitzer Prize for his reporting on Nagasaki, which came out considerably after the bombing itself took place. There are some who have called for the revocation of this prize, because he was effectively acting as a form of Army propaganda. This is true enough, though the line between "propaganda" and "embedded reporting" (or even "privileged source") is a tricky one, then and now. Did Laurence glamorize the Manhattan Project? Sure — he thought it was the beginning of a new age of humanity, perhaps one in which war would be eliminated and we'd soon be colonizing the stars. That Buck Rogers view of things contrasts sharply with the human suffering enacted at Hiroshima and Nagasaki, and the forthcoming dangers of the Cold War, but you can see how he got seduced by the sheer sci-fi aspects of the project. He was hardly unique in that view.

Laurence is sometimes criticized today for not reporting more on the effects of radiation from the bomb. Personally, I give Laurence a bit of a pass on this: the experts he was talking to (Oppenheimer and many others) told him radiation was not such a big deal, that anyone who would be affected by radiation would already probably have been killed by the blast and thermal effects of the bomb. They were wrong, we now know. But the US atomic experts didn't figure that out until after they had sent their own scientists to Japan in the immediate postwar, and they didn't trust Japanese reports during the war because they suspected they were propaganda. I don't really think we can fault Laurence for not knowing more than the best experts available to him at the time, even though we now know those experts were wrong. I've never seen anything to indicate that Laurence himself thought he was telling any falsehoods.

Laurence continued to write about the bomb for much of his life. He took a strong stance against the creation of the hydrogen bomb (which he dubbed "The Hell Bomb") and never was closely aligned with the atomic weapons sector again. It's hard to imagine someone like Laurence — part huckster, part journalist, all wild-card — being allowed into something as secret as the nuclear weapons program today. He's improbable in every way, a real-life character with more strangeness than would seem tolerable in pure fiction.

The plot against Leo Szilard

Friday, October 23rd, 2015

One of the recurring themes on WGN America's Manhattan is the willingness of Manhattan Project security to use extreme extrajudicial methods against scientists on the project they found suspicious, problematic, or dangerous. Episode 2 of this second season centered on an extreme case of this, with the main character, fictional scientist Frank Winter, being locked up without Constitutional protections (to say the least) in an effort to discover where his true loyalties lay. As ought to be pretty obvious, this isn't (as far as we know) something that happened in real life: you can't lock up all of your scientists if you expect to get a bomb built before the war ends.

However, this aspect of the plot is inspired by a healthy dose of actual history — even if it is history that is not always well-known. General Leslie Groves and the Manhattan Project security services did occasionally dabble in extrajudicial authority, taking advantage of the fact that the bomb project had its own, wholly autonomous security and intelligence force, and that wartime pressures allowed them to do things that were quite a bit outside of business-as-usual.

Leo Szilard is one of the many historical characters who is distilled into Frank Winter's personality. Szilard is one of the real characters of the Manhattan Project. A Hungarian émigré, he was the one who came up with the idea of the nuclear chain reaction, he was the one who urged the scientists self-censor their research, he was the one who got his friend Albert Einstein to write a letter to President Roosevelt calling for government coordination of fission research, and he was the one who circulated a petition against the dropping of the atomic bomb during the war. Frank Winter's moral arc — moving from deep conviction about the need to rapidly build a bomb, to plaguing doubts — is heavily inspired by Szilard.1

But Szilard could also be a huge pain in the neck. He was a natural gadfly, brilliant and utterly lacking respect for authority. It wasn't just the military he ran into trouble with. The scientists Arthur Compton, Vannevar Bush, and James Conant all eventually ran afoul of Szilard's views on what they ought to be doing, and each of them in turn found themselves highly irritated with Szilard. If Szilard worked under you, he inevitably became frustrated with you and your decisions, because no one was good enough for Leo Szilard. And his complete inability to just grin and bear it guaranteed that, over time, that feeling of frustration would become mutual. This put even his allies in a tough place, because while no one could deny Szilard's brilliance or contributions to the bomb project, they also didn't want to spend too much time with him.

But it was General Groves who really, really took an active dislike to Szilard. His views on him are aptly discussed in a June 1945 memo that Groves had drawn up:

Szilard is a physicist who has worked on the project almost since its inception. He considers himself largely responsible for the initiation of the project, although he really had little to do with it. When the Army took over the project, an intensive investigation was made of Szilard because of his background and uncooperative attitude on security matters. This investigation and all experience in dealing with him has developed that he is untrustworthy and uncooperative, that he will not fulfill his legal obligations, and that he appears to have no loyalty to anything or anyone other than himself. He was retained on the project at a large salary solely for security reasons.2

In the postwar, Groves was even more to the point. Szilard was, he explained to an interviewer, "the kind of man that any employer would have fired as a troublemaker."3

Szilard and the military were a particularly bad fit. Szilard thought the military did things badly, and, in the end, that there were some bad people at the top. He didn't hide his feelings on the matter. Rather, he blatantly told many people them — he feared the American military would assert a dictatorship, would use the bombs in a terrible way, and would jeopardize the future peace of the planet.

And, from a certain perspective, he wasn't too far off the mark. The Manhattan Project was asserting quasi-dictatorial powers during the war (and the bomb did bring with it rigid hierarchies, abnormal secrecy, and a lack of democratic process wherever it went in the Cold War), they were planning to use the bomb on civilians to make their point (which one can agree with or disagree with as a strategy), and they were decidedly not interested in any approach to world peace other than building up a large American nuclear arsenal (which in Szilard's mind was a path to global suicide).

So you can see why he occasionally felt he might be better off not connected with such a project, and why he did (multiple times) attempt to jump the "chain of command" to contact civilian authorities (including both Presidents Roosevelt and Truman) to speak to him about his fears.

And you can understand why General Groves found this sort of behavior tantamount to treason. But as long as Szilard was under the watchful eye of the Manhattan Project security apparatus, Groves would tolerate him for the duration of the war — it was better to have Szilard close (and thus known), than it was to have him "in the wind."

But in October 1942, for one brief moment, it was feared that Szilard might quit the project. Compton had attempted to move him out of the project in Chicago, and worried that Szilard might just take off. He was wrong — they worked out an agreement — but the fear of a disgruntled Leo Szilard prompted Groves to draw up a draft of an extraordinary order in the name of the Secretary of War:

October 28, 1942

The Honorable,
The Attorney General.

Dear Mr. Attorney General:

The United States will be forced without delay to dispense with the services of Leo Szilard of Chicago, who is working on one of the most secret War Department projects.

It is considered essential to the prosecution of the war that Mr. Szilard, who is an enemy alien, be interned for the duration of the war.

It is requested that an order of internment be issued against Mr. Szilard and that he be apprehended and turned over to representatives of this department for internment.

Sincerely yours,

Secretary of War.4

It was never sent. As far as we know, Groves never interned anyone in this manner during the war — though he did entertain the idea at least one other time, in the case of Hans Halban, another immigrant nuclear scientist with strong opinions and dubious loyalties (Halban was French, which is Groves' book ranked slightly worse than Hungarian).

But he didn't leave Szilard alone. He kept a close watch on Szilard and Szilard's associates, even having the scientist tailed by Special Agents are various times during the war. He never learned very much of interest from these tails (and from the reports of Szilard's actions, one suspects Szilard was at times aware of them), but one can imagine how delighted he would have been to have a good reason to throw Szilard in a cell and lose the key. "The investigation of Szilard should be continued despite the barrenness of the results," Groves wrote in June 1943. "One letter or phone call once in three months would be sufficient for the passing of vital information."5

Groves kept up an active Szilard file through 1946. Szilard knew a lot, and Groves did not trust him. There is evidence in the files that Groves was trying to build an espionage case against Szilard around the time Szilard was trying to circulate his petitions against the dropping of the atomic bomb. But, no doubt to Groves' frustration, it came to nothing.

But Groves kept Szilard on the payroll. Keep your friends close, and your gadfly scientists even closer, I suppose.

Can we imagine a world in which things had gone another way? In which Groves might have decided that the fear of a free-range Leo Szilard, running around the world doing who-knows-what and talking to who-knows-who, would be worth locking him up without hearing, representation, or appeal? What is one scientist in the light of the stakes that someone like Groves attached to this project?

It is impressive, in retrospect, that Groves, in the end, showed as much restraint as he did — Szilard was a troublemaker. But arguably, some of that trouble needed to be made.

To demonstrate, or not to demonstrate?

Friday, March 6th, 2015

As the atomic bomb was becoming a technological reality, there were many scientists on the Manhattan Project who found themselves wondering about both the ethics and politics of a surprise, unwarned nuclear attack on a city. Many of them, even at very high levels, wondered about whether the very threat of the bomb, properly displayed, might be enough, without the loss of life that would come with a military attack.

1945-06-12 - Franck Report

The Franck Report, written in June 1945 by scientists working at the University of Chicago Metallurgical laboratory, put it perhaps most eloquently:

...the way in which nuclear weapons, now secretly developed in this country, will first be revealed to the world appears of great, perhaps fateful importance. ... It will be very difficult to persuade the world that a nation which was capable of secretly preparing and suddenly releasing a weapon, as indiscriminate as the rocket bomb and a thousand times more destructive, is to be trusted in its proclaimed desire of having such weapons abolished by international agreement.... 

From this point of view a demonstration of the new weapon may best be made before the eyes of representatives of all United Nations, on the desert or a barren island. The best possible atmosphere for the achievement of an international agreement could be achieved if America would be able to say to the world, "You see what weapon we had but did not use. We are ready to renounce its use in the future and to join other nations in working out adequate supervision of the use of this nuclear weapon."

They even went so far as to suggest, in a line that was until recently totally etched out of the historical record by the Manhattan Project censors, that "We fear its early unannounced use might cause other nations to regard us as a nascent Germany."

The idea of a "demonstration" was for many scientists a compelling one, and news of the idea spread to the various project sites. The idea would be to let the Japanese know what awaited them if they did not surrender. This would be more than just a verbal or textual warning, which could be disregarded as propaganda — they would set the bomb off somewhere where casualties would be low or minimal, but its nature easy to verify. If the demonstration did not work, if the Japanese were not receptive, then the bomb could be used as before. In the eyes of these scientists, there would be no serious loss to do it this way, and perhaps much to gain.

Of course, not all scientists saw it this way. In his cover letter forwarding the Franck Report to the Secretary of War, the physicist Arthur Compton, head of the Chicago laboratory, noted his own doubts: 1. if it didn't work, it would be prolonging the war, which would cost lives; and 2. "without a military demonstration it may be impossible to impress the world with the need for national sacrifices in order to gain lasting security." This last line is the more interesting one in my eyes: Compton saw dropping the bomb on a city as a form of "demonstration," a "military demonstration," and thought that taking a lot of life now would be necessary to scare the world into banning these weapons in the future. This view, that the bombs were something more than just weapons, but visual arguments, comes across in other scientists' discussions of targeting questions as well.

Truman was never asked or told about the demonstration option. It is clear that General Groves and the military never gave it much thought. But the Secretary of War did take it serious enough that he asked a small advisory committee of scientists to give him their thoughts on the matter. A Scientific Panel, composed of J. Robert Oppenheimer, Arthur Compton, Enrico Fermi, and Ernest Lawrence, weighed in on the matter formally, concluding that: "we can propose no technical demonstration likely to bring an end to the war; we see no acceptable alternative to direct military use."1

I find this a curious conclusion for a few reasons. For one thing, are these four scientists really the best experts to evaluate this question? No offense, they were smart guys, but they are not experts in psychological warfare, Japanese political thought, much less privy to intercepted intelligence about what the Japanese high command was thinking at this time. That four physicists saw no "acceptable alternative" could just be a reflective of their own narrowness, and their opinion sought in part just to have it on the record that while some scientists on the project were uncomfortable with the idea of a no-warning first use, others at the top were accepting of it.

But that aside, here's the other fun question to ponder: were they actually unanimous in their position? That is, did these four physicists actually agree on this question? There is evidence that they did not. The apparent dissenter was an unlikely one, the most conservative member of the group: Ernest Lawrence. After the bombing of Hiroshima, Lawrence apparently told his friend, the physicist Karl Darrow, that he had been in favor of demonstration. Darrow put this into writing on August 9, 1945, to preserve it for posterity should Lawrence come under criticism later. In Darrow's recollection, Lawrence debated it with the other scientists for "about an hour" — a long-enough time to make it seem contentious. On August 17, after the bomb had "worked" to secure the peace, Lawrence wrote back to Darrow, somewhat denying this account, saying that it was maybe only ten minutes of discussion. Lawrence, in this later account, credits Oppenheimer as being the hardest pusher for the argument that unless the demonstration took out a city, it wouldn't be compelling. I'm not sure I completely believe Lawrence's later recant, both because Darrow seemed awfully convinced of his recollection and because so much changed on how the bomb was perceived after the Japanese surrendered, but it is all an interesting hint as some of the subtleties of this disagreement that get lost from the final documents alone. In any case, I don't know which is more problematic: that they debated for an hour and after all that, concluded it was necessary, or that they spent no more than ten minutes on the question.2

1945-08-10 - Groves memo on next bombs

As an aside, one question that sometimes gets brought up at this point in the conversation is, well, didn't they only have two bombs to use? So wouldn't a demonstration have meant that they would have only had another bomb left, perhaps not enough? This is only an issue if you consider the timescale to be as it was played out — e.g., using both bombs as soon as possible, in early August. A third plutonium bomb would have been ready by August 17th or 18th (they originally thought the 24th, but it got pushed up), so one could imagine a situation in which things were delayed by a week or so and there would have been no real difference even if one bomb was expended on a demonstration. If they had been willing to wait a few more weeks, they could have turned the Little Boy bomb's fuel into several "composite" core implosion bombs, as Oppenheimer had suggested to Groves after Trinity. I only bring the above up because people sometimes get confused about their weapon availability and the timing issue. They made choices on this that constrained their options. They had reasons for doing it, but it was not as if the way things happened was set in stone. (The invasion of Japan was not scheduled until November 1st.)3

So, obviously, they didn't choose to demonstrate the bomb first. But what if they had? I find this an interesting counterfactual to ponder. Would dropping the bomb in Tokyo Bay have been militarily feasible? I suspect so. If they could drop the bombs on cities, they could probably drop them near cities. To put it another way: I have faith they could have figured out a way to do it operationally, because they were clever people.4

But would it have caused the Japanese high command to surrender? Personally, I doubt it. Why? Because it's not even clear that the actual atomic bombings were what caused the Japanese high command to surrender. There is a strong argument that it was the Soviet invasion of Manchuria that "shocked" them into their final capitulation. I don't know if I completely buy that argument (this is the subject of a future blog post), but I am convinced that the Soviet invasion was very important and disturbing to the Japanese with regards to their long-term political visions for the country. If an atomic bomb dropped on an actual city was not, by itself, entirely enough, what good would seeing a bomb detonated without destruction do? One cannot know, but I suspect it would not have done the trick.

Of course, the Chicago scientists suspected that as well, but said it was necessary from a moral point of view. Sure, the Japanese might not surrender, but then, at least, you can say you showed them what was coming first.  As it was, we gave no real warning whatsoever before dropping it on Hiroshima. But here's the question I come to next: could you demonstrate it, and then drop it on a city? That is, could the United States really say: "we have made this apocalyptic weapon, unleashed the atom, and many other peril/hope clichés — and we have chosen not to use it to take life... yet. But if you don't give in to our demands, we will unleash it on your people." How could that not look like pure blackmail, pure terrorism? Could they then turn around and start killing people by the tens of thousands, having announced their capability to do so? Somehow I suspect the public relations angle would be almost impossible. By demonstrating it first, they would be implying that they knew that it was perhaps not just another weapon, not just another way to wage war. And that acknowledgment would mean that they would definitely be seen as crossing a line if they then went on to use it.

As it was, that line, between the bomb as "just another weapon" and something "special," was negotiated over time. I think the demonstration option was, for this reason, never really going to be on the table: it would have forced the American policymakers to come to terms with whether the atomic bomb was a weapon suitable for warfare on an earlier schedule than they were prepared to. As it was, their imagery, language, and deliberations are full of ambiguity on this. Sometimes they thought it would have new implications for "man's position in the universe" (and other "special bomb" notions), sometimes they thought it was just an expedient form of firebombing with extra propaganda value because it would be very bright and colorful. Secrecy enabled them to hedge their bets on this question, for better or worse.

Without imagery like this, would the world fear nuclear weapons more, or less?

Without imagery like this, would the world fear nuclear weapons more, or less? When, if ever, would the first use of nuclear weapons in warfare have been?

So who was right? I don't know. We can't replay history to see what happened, obviously. I think the idea of a demonstration is an interesting expression of a certain type of ethical ideal, though it went so far against the practical desires of the military and political figures that it is hard to imagine any way it would have been pursued. I am not sure it would even have been successful, or resolved the moral bind of the atomic bomb.

I do find myself somewhat agreeing with those scientists who said that perhaps it was better to draw blood with the smaller, cruder bombs, before the really big ones came around — and they knew those were coming. If we didn't have Hiroshima and Nagasaki, what would we point to, to talk about why not to use nuclear weapons? Would people think the bombs were not that impressive, or even more impressive than they were? I don't know, but there is something to the notion that knowing the gritty, gruesome reality (and its limitations) is better than not. It took the Holocaust for the world to (mostly) renounce genocide, maybe it took Hiroshima and Nagasaki for the nuclear taboo to be established (arguably). That, perhaps, is the most hopeful argument here, the one that sees Hiroshima and Nagasaki as not just the first cities to be atomic bombed, but the last, but I am sure this is little solace to the people who were in those cities at the time.

If it was detonated underwater the fallout would be mostly limited to the area around the bomb detonation itself. It would be hard to actually create a lot of fallout with a bomb detonated over water and not land, in any case. "Local fallout," the acutely deadly kind, is caused in part by the mixing of heavier dirt and debris with the radioactive fireball, which causes the fission products to descend very rapidly, while they are still very "hot."

Oppenheimer, Unredacted: Part II – Reading the Lost Transcripts

Friday, January 16th, 2015

This is the second and final part (Part II) of my story about the lost Oppenheimer transcripts. Click here for Part I, which concerns the origin of the transcripts, the unintuitive aspects of their redaction, and the unorthodox archival practice that led me to find their location in 2009.

The Oppenheimer security hearing transcript is not exactly beach reading. Aside from its length (the redacted version alone is some 690,000 words, which makes it considerably longer than War and Peace), it is also a jumble of witnesses, testimonies, and distinct topics. It is also somewhat of a bore, as there is incredible repetition, and unless you know the context of the time very well, the specific arguments that are focused on can seem arbitrary, pedantic, and confusing, even without the additional burden of some of the content having been deleted by the censor.

The most damning problem for Oppenheimer at his 1954 hearing involved his conduct during the so-called “Chevalier incident,” in which a fellow-traveler colleague of his at Berkeley, Haakon Chevalier, approached Oppenheimer at a party in late 1942 or early 1943 at the behest of another scientist (a physicist named George Eltenton) who wanted to see if Oppenheimer was interested in passing on classified information to the Soviet Union. Oppenheimer, in his recollection, told Chevalier in no uncertain terms that this was a bad idea. Later, Oppenheimer went to a member of the Manhattan Project security team and told him about the incident, calling attention to Eltenton as a security risk, but also trying to not to make too big of a deal of the entire matter. Confronted with the idea of Soviet spying on the atomic bomb project, the security men of course did not take it so lightly, and pressed Oppenheimer for more details, such as the name of the intermediary, Chevalier, which Oppenheimer did not want to give since he claimed Chevalier had nothing truly to do with Soviet spying. Over the course of several years, the security agents re-interviewed Oppenheimer, trying to clarify exactly what had happened. Oppenheimer gave contradictory answers, seemingly to shield his friends from official scrutiny and its consequences. At his hearing, when asked whether he had lied to security officials, Oppenheimer admitted that he had. When asked why, Oppenheimer gave what was become the most damning testimony at a hearing about his character: “Because I was an idiot.” Not a good answer to have to give under any context, much less McCarthyism, much less when you are known to be brilliant.

I mention this only to highlight the difference between what is in the published transcript and what is not. The newly unredacted information does not touch on the Chevalier incident much at all. That is, it does not shed any new light on the central question of relevance towards Oppenheimer's security clearance. What does it shed light on? We can lump its topics into roughly three categories.

One of the censor's trickier redactions, in which he removed a trouble word, and substituted a different word in its place. "Principle" was too close to a secret, but"idea" was acceptable.

One of the censor's trickier redactions, in which he removed a trouble word, and substituted a different word in its place. "Principle" was too close to a secret, but"idea" was acceptable. (JB = James Beckerley.)

The first category concerns the creation of the hydrogen bomb. Oppenheimer had been on a committee that had opposed a “crash” program to build the H-bomb in 1949. This was at a time when it was unclear that such a weapon could be built at all. The then-favored design (later dubbed the “Classical Super”) had many problems with it, and didn’t seem like it was likely to work. It seemed to also require huge quantities of a rare isotope of hydrogen, tritium, the production of which could only be done in nuclear reactors at the expense of producing plutonium.For Oppenheimer and many others, there was a strong technical reason to not rush into an H-bomb program: it wasn’t clear that the bomb could be built, and preparing the materials for such a bomb would decrease the rate of producing regular fission bombs.

How much plutonium would be lost in pursuing the Super? This is an area the newly-reduced transcript does enlighten us. Gordon Dean, Chairman of the Atomic Energy Commission from 1950 to 1953, explained that:

You don't decide to manufacture something that has never been invented. Nothing had been invented. No one had any idea what the cost of this thing would be in terms of plutonium bombs. As the debate or discussions waged in the fall of 1949, we had so little information that it was very difficult to know whether this was the wise thing to do to go after a bomb that might cost us anywhere from 20 plutonium bombs up to 80 plutonium bombs, and then after 2 or 3 years effort find that ft didn't work. That was the kind of problem. So there were some economics in this thing.

The underlined section was removed from the published transcript. This does contribute to the debate at the time — if researching the Super meant depriving the US stockpile of 20-80 fission bombs, that is indeed a high price. We might ask: Why was it redacted? Because the censor wanted to undercut Oppenheimer's position? Probably not — if the censor had wanted to do that, he would have removed a lot more than just those numbers. More likely it is because you can work backwards from those numbers how much plutonium was in US nuclear weapons at that time, or, conversely, how much tritium they were talking about. Every atom of tritium you make is an atom of plutonium you don't make — and plutonium atoms are 80X heavier than tritium atoms. So for every gram of tritium you produce, you are missing out on 80 grams of plutonium. If you know that the bombs at the time had around 6 kg of plutonium in them, then you can see that they are talking about the expense of making just 1.5 to 6 kg of tritium. Should this have been classified? It seems benign at the moment, but this was still a period of a "race" for thermonuclear weapons, and nearly everything about these weapons was, rightly or wrongly, classified.

Redaction of a long section on the development of the Teller-Ulam design. Ulam's name was almost totally (but not entirely) removed from the transcript, sometimes very deliberately and specifically. The orange pencil shows the mark of the censor, as does the "Delete, JB" on the right.

Redaction of a long section on the development of the Teller-Ulam design. Ulam's name was almost totally (but not entirely) removed from the transcript, sometimes very deliberately and specifically. The orange pencil shows the mark of the censor, as does the "Delete, JB" on the right.

But the hydrogen bomb could be built. In the spring of 1951, physicists Edward Teller and Stanislaw Ulam hit upon a new way to build a hydrogen bomb. It was, from the point of view of the weapons physicists, a totally different approach. Whereas the “Classical Super” required using an atomic bomb to start a small amount of fusion reactions that would then propagate through a long tube of fusion fuel, the “Equilibrium Super,” as the so-called Teller-Ulam design was known at the time, involved using the radiation of an atomic bomb to compress a capsule of fusion fuel to very high densities before trying to ignite it. To a layman the distinction may seem minor, but the point is that many of the scientists involved with the work felt this was really quite a big conceptual leap, and that this had political consequences.

The differences between the redacted and un-redacted transcript shows a censor who tried, perhaps in vain, to dance around this topic. The censor clearly wanted to make sure the reader knew that the hydrogen bomb design developed in 1951 (the “Equilibrium Super”) was a very different thing than the one on the table in 1949 (the “Classical Super”), because this is a clear part of the argument in Oppenheimer’s favor. But the censor also evidently feared being too coy about what the differences between the 1949 and 1951 designs were, as such was the entire “secret” of the hydrogen bomb. For example, here is a section where Oppenheimer testified on this point, early on in the hearing:

In the spring of 1951, there were some inventions made. They were not discoveries, really; they were inventions, new ideas, and from then on it became clear that this was a program which was bound to succeed. It might not succeed at first shot; you might make mistakes, but for the first time it was solid. It was not on the end; it wasn’t so that every time you calculated it it was yes or not, but it came out that you knew that you could do not. It was just a question of how rapidly and how well and I am amazed at the speed at which this actually went after we learned what to do. Ulam and Teller had some very bright ideas; why none of us had them earlier, I cannot explain, except that invention is a somewhat erratic thing.

Again, what is underlined above was removed from the original. Read the sentences without them and they still have the same essential meaning: Oppenheimer is arguing that the 1951 design was very different than the 1949 one. Put them back in, and the meaning only deepens a little, adding a little more specifics and context, but does not change. One still understands Oppenheimer’s point, and much is left in to emphasize its import — Oppenheimer only opposed the H-bomb when it wasn’t clear that an H-bomb could be made.

Why remove such lines in the first place? A judgment call, perhaps, about not wanting to reveal that the “secret” H-bomb was not a new scientific fact, but a clever application of a new idea. The censor could have probably justified removing more under the security guidelines, but took pains to maintain coherency in the testimony. In one place, the physicist Hans Bethe referred to Teller and Ulam’s work as a new “principle,” and the censor re-worded this to “idea” instead. A subtle change, but certainly done in the name of security, to shift attention away from the nature of the H-bomb “secret.”

Early 1954 was a tricky time for hydrogen bomb classification. The US had detonated its first H-bomb in 1952, but not told anyone. In March 1954, a second hydrogen bomb was detonated as the “Bravo test.” Radioactive fallout rained down on inhabited atolls in the Marshall Islands, as well as a Japanese fishing boat, making the fact of it being a thermonuclear test undeniable. The Soviet Union had detonated a weapon that used fusion reactions in 1953, but did not appear to know about the Teller-Ulam design. As a result, US classification policy on the H-bomb was extremely conservative and sometimes contradictory; that the US had tested an H-bomb was admitted, but whether it was ready to drop any of them was not.

JRO redaction Rabi mermaids

In this category I would also attribute I.I. Rabi's "mermaids" redaction, mentioned earlier. As published, it was:

We have an A-bomb and a whole series of it, *** and what more do you want, mermaids?

Restored, it is:

We have an A-bomb and a whole series of it, and we have a whole series of Super bombs, and what more do you want, mermaids?

To the censor, the removed section implied, perhaps, that there was no single H-bomb design, but rather a generalized arrangement that could be applied to many different weapons (which were being tested during Operation Castle, which was taking place at the same time as these hearings). This is a tricky distinction for a layman, but important for a weapons designer — and it is the eyes of the weapon designer that the censor feared, in this instance.

The censor’s fear of foreign scientists scouring the Oppenheimer hearing transcripts for clues as to the H-bomb’s design was not, incidentally, unwarranted. In the United Kingdom, scientists compiled a secret file full of extracts from the (redacted) Oppenheimer transcript that reflected on the nature of the successful H-bomb design. So at least one country was watching. As for the Soviet Union, they detonated their first H-bomb in 1955, having figured out the essential aspects of the Teller-Ulam design by the spring of 1954 (there is still scholarly uncertainty as to the exact chronology of the Soviet H-bomb development, and whether it was an entirely indigenous creation).

Project Vista cover page

The second major category of deletions pertained to Oppenheimer’s role in advising on the use of tactical nuclear weapons in Europe. This involved his participation in Project Vista, a study conducted in 1951-1952 by Caltech for the US Army. Vista was about the defense of continental Europe against overwhelming Soviet ground forces, and Oppenheimer’s section concerned the use of atomic bombs towards this end. (It was named after the hotel that the summer study took place in.)

Oppenheimer’s chapter ("Chapter 5: Atomic Warfare") concluded that small, tactical fission bombs could be successfully used to repel Soviet forces. In doing so, it also argued against a reliance on weapons that could only be used against urban targets — like the H-bomb. The US Air Force attempted to suppress the Vista report, because it seemed to advocate that the Army into their turf and their budget. It was one of the many things that made the Air Force sour on Oppenheimer.1

In order to emphasize that Oppenheimer was not opposed to the hydrogen bomb on the basis of entirely moralistic reasons, a lot of the discussions at the hearing initiated by his counsel related to his stance on tactical nuclear weapons. They wanted it to be clear that Oppenheimer was not “soft” on Communism and the USSR. Arguably, Oppenheimer’s position was sometimes more hawkish than those of the H-bomb advocates. Oppenheimer wanted a nuclear arsenal that the US would feel capable of using, as opposed to a strategic arsenal that would only lead to a deterrence stalemate.

Another classic Cold War redaction: what we know about the enemy, even if we don't know anything.

Another classic Cold War redaction: what we know about the enemy, even if we don't know anything.

The debate of strategic arms versus tactical nukes is one that would become a common point of discussion from the 1960s onward, but in 1954 it was still confined largely to classified circles because they pertained to actual US nuclear war plans in place at the time and the future of the US nuclear arsenal. Much of this discussion is still visible in the redacted transcript, but with less emphasis and detail than in the un-redacted original. The essential point — that in the end, the US military pursued both of these strategies simultaneously, and that Oppenheimer was no peacenik — gets filled out a more clearly in the un-redacted version.

Among the sentences that got redacted are long portions that describe the Vista project, its importance, and the fact that it was taken very seriously. It is unfortunate that these were removed, because they would definitely have changed the perception that Oppenheimer was acting on purely "moral" reasons against the hydrogen bomb. Oppenheimer opposed the hydrogen bomb, but he did so, in part, because he advocated making hundreds of smaller fission bombs. Other statements removed is a remark by General Roscoe Charles Wilson about something he heard Curtis LeMay say: "I remember his saying most vigorously that they couldn't make them too big for him." One can appreciate why the censor might want to remove such a thing, as a rather unflattering bit of hearsay about the head of the Strategic Air Command. Lest one think that these removals would only help Oppenheimer's case, many of the other lines removed from Wilson's testimony concerned the fact that the Air Force did find that they had plenty of strategic targets for multi-megaton bombs — removed, no doubt, because it shed light on US targeting strategy, but the sort of thing that generally went against Oppenheimer's argument.

Similarly, John McCloy testified that Oppenheimer's views were fairly hawkish at the time:

I have the impression that he [Oppenheimer], with one or two others, was somewhat more, shall I say, militant than some of the other members of the group. I think I remember very well that he said, for example, that we would have to contemplate and keep our minds open for all sorts of eventualities in this thing even to the point of preventative war.

Did Oppenheimer really advocate preventative nuclear war with the Soviet Union? It's not impossible — his views in the 1950s could be all over the place, something that makes him a difficult figure to fit into neat boxes. In retrospect, we have made Oppenheimer into an all-knowing, all-rational sage of the nuclear age, but the historical record shows someone more complicated than that. Why would the censor remove the above? Probably because it would be seen as inflammatory to US policy, potentially because it might shed light on actual nuclear policy discussions. In this case, this line potentially could have had a strong impact on the post-hearing memory of Oppenheimer, had it been released, but probably not a positive one.

JRO redaction Groves on Rosenbergs

Lastly, there are a few removals for miscellaneous reasons relating to the conduct of the hearings themselves. As I pointed out at the beginning, when the witnesses at the security hearing took the stand, they were told that their responses would be “strictly confidential,” and not published. This was to encourage maximum candor on their part. When the decision was made to publish the transcript, each of the witnesses were contacted individually to be told this and were asked if there was anything they would not want made public. There is evidence of a few removals for this reason.

General Leslie Groves, the head of the Manhattan Project during World War II, said a number of things that were not classified but would have been embarrassing or controversial if they appeared in print. For example, he was emphatic that “the British Government deliberately lied about [Klaus] Fuchs,” the German physicist who had been part of the British delegation to Los Alamos and was, as it later became known, a Soviet spy. Groves also opined on the importance of Fuchs’ espionage versus that of the Rosenbergs:

I think the data that went out in the case of the Rosenbergs was of minor value. I would never say that publicly. Again that is something while it is not secret, I think should be kept very quiet, because irrespective of the value of that in the overall picture, the Rosenbergs deserved to hang, and I would not like to see anything that would make people say General Groves thinks they didn't do much damage after all.

Even Groves’ comment at the time made it clear that this was not something he wanted circulated publicly. Should this information have been removed? It is a tricky question. If Groves had known what he said would be printed, he never would have said any of it. Ultimately this becomes not an issue of classification, but one of propriety. Its inclusion does not affect issues relating to Oppenheimer’s clearance. It is part of a much longer rant on Groves' part about the British, something he was prone to do when confronted with the fact that the worst cases of nuclear secrets being lost occurred on his watch.

In one slightly smaller category, there is at least evidence of one erroneous, accidental removal. There is a line, on page 129 of the GPO version, which, when restored, looks like this: "Having that assumption in mind at the time Lomanitz joined the secret project, did you tell the security officers anything that you knew about Lomanitz’s background?" The restored material contains nothing classified, or even interesting, and its removal is not noted in the official "concordance" of deleted material produced by the Atomic Energy Commission censor. So why was it removed? Looking at the originals, we find that the entire contents of the deleted material comprise the last line of the page. It looks like it got cut off on accident, and marked as a redaction. Such is perhaps further evidence of the rushed effort that resulted in the transcript being published.

* * *

Does the newly released material give historians new insight into J. Robert Oppenheimer? In my view: not really. At best, they may address some persistent public misconceptions about Oppenheimer, but ones that have long since been redressed by historians, and ones that even the redacted transcript makes clear, if one takes the time to read it carefully and deeply. The general public has long perceived Oppenheimer to be a dovish martyr, but even a cursory reading of the actual transcripts makes it clear that this is not quite right — he was something more complex, more duplicitous, more self-serving.

Oppenheimer's two TIME magazine covers: as ascendent atomic expert (1948), and casualty of the security state (1954).

Oppenheimer's two TIME magazine covers: as ascendent atomic expert (1948), and casualty of the security state (1954).

If the redacted sentences had been released in 1954, they would have fleshed out a little more of the story behind the H-bomb and behind Oppenheimer’s advocacy for tactical nuclear weapons. They would have emphasized more strongly that Oppenheimer opposed the H-bomb not just for moral reasons, but for technical reasons, and that rather than opposing the development of atomic armaments, Oppenheimer supported them vigorously — and even supported using them in future conflicts. The latter aspect, in particular, might have changed a bit the public’s perception of Oppenheimer at the time. Oppenheimer was not a dove, he was just a different sort of hawk, which somewhat reduces the idea of Oppenheimer as a martyr against the warmongers. This latter notion (Oppenheimer as anti-nuke) is a common perception of Oppenheimer, even today, though much scholarly work has tried to go against this notion for several decades.

The recent declassification of the transcript does not tell us anything we essentially did not already know from other sources, including the many of the wonderfully-researched histories of this period published in recent years by scholars such as Jeremy BernsteinKai Bird, David Cassidy, Gregg Herken, Priscilla McMillan, Richard Polenberg, Richard Rhodes, Sam SchweberMartin Sherwin, and Charles Thorpe, among others. These new revelations do not drastically revise our understanding of Oppenheimer or his security clearing. He looks no more nor less of a “security risk” than he did in the redacted version of the transcripts.

At the same conference where I initially was inspired to search for the hearing transcripts, Polenberg asked the group assembled: how would we remember Oppenheimer today, if he had not had his security clearance stripped after the hearing? His own answer is that we would probably have longer focused on the more negative aspects of Oppenheimer's personality and perspectives. We'd see him not as a dove, but as a different flavor of hawk. He'd see him as someone who was willing to turn in his friends to the FBI, if it served his interests. We'd see him as someone who, again and again, wanted to be accepted by the politicians and the generals. We would see more of his role as an enabler of the Cold War arms race, not just his attempts at tamping it down. By revoking the clearance, Oppenheimer's enemies may have crushed his soul, but they made him a martyr in the process.

Headlines from 1954 regarding Beckerley and his split with the Atomic Energy Commission — and his turn as a secrecy critic.

Headlines from 1954 regarding Beckerley and his split with the Atomic Energy Commission — and his turn as a secrecy critic.

But just because these transcripts don't give us much of a revision on Oppenheimer, or the conduct of his security hearing, doesn't mean they are not  instructive. For one thing, they shed a good deal of light on the process of secrecy itself — and it is only by getting the full story, the record of deletions, that one can pass judgment on whether the secrecy was used responsibility or inappropriately.

In my view, the erasures appear to have been done responsibly. They do not greatly obscure the ultimate arguments for or against Oppenheimer’s character, and primarily hew to legitimate security concerns for early 1954. The choice of what to remove and what to keep was done not by one of Oppenheimer’s enemies, but by Dr. James G. Beckerley, a physicist who was at the time the Director of the Atomic Energy Commission’s Division of Classification. His initials (“JB”) can be found next to many of the specific deletions in some of the volumes. Beckerley was no rabid anti-Communist or promoter of secrecy. He was a moderate, one who often felt that the AEC’s security rules were highly problematic, and believed that only careful and sane application of classification rules (as opposed to zealous or haphazard) would lead to a stronger nation. As it was, he resigned his job in May 1954, not long after the Oppenheimer hearing, and became an outspoken critic of nuclear secrecy. We do not know Beckerley’s personal opinions on Oppenheimer, but in every other aspect of his work he seems not to be the classification villain that one expects of a Cold War drama.

So it is perhaps not surprising that his deletions from the Oppenheimer transcript are, in retrospect, pretty reasonable, if viewed in context. They do not seem overtly politicized, especially in the way that Beckerley carefully carved up some of the problematic statements so that their ultimate argument still came out, even if the classified details did not. Most were plausibly done in the name of security, according to the security concerns of early 1954. In fact, the amount of discussion of the H-bomb’s development allowed in the final transcript is rather remarkable — very little has in fact been removed on this key topic. A few of the removals, were done in the name of propriety, removed because of the changing status of the transcript from “confidential” to public record. None of the comments removed for non-security reasons seem to have had any bearing on the question of Oppenheimer’s character and loyalty, though they are certainly interesting. Groves’ comments on the Rosenbergs, for example, is completely fascinating — but not relevant to Oppenheimer’s case.

In this case, I disagree with the conclusions given by the other historians in the New York Times article about the release. I don't think the removals bolster Oppenheimer's case, and I don't think there is any evidence to suggest that the redactions were made to aid the government's case. We are accustomed to a story about classification that involves bad guys hiding the truth. Sometimes that is a narrative that works well with the facts — classification can, and has often been, abused. But in my (someday) forthcoming book, I argue that part of this impression of "the censor" as a shadowy, faceless, draconian "enemy" is just what happens when we, on the outside, are not privy to the logic on the "inside."

It is somewhat tautological to say that secrecy regimes hide their own logic by the very secrecy they impose, but it is actually a somewhat subtle point for thinking about how they work. When you are outside of a secrecy regime, you can't always see why it acts the way it does, and it is easy to see it as an oppositional entity designed to thwart you. Peeling back the layers, which is what historians can do many years after the fact, often reveals a more subtle and complex organizational discussion going on. In the case of these transcripts, it is clear, I think, that Beckerley was trying his best to satisfy both the security requirements of the day regarding the key features of the newly-invented hydrogen bomb, as well as avoid saying too much about US nuclear force postures in Europe. And, just as key, he was juggling the problem of witnesses who had been told their original testimony would be confidential. There is no evil intent in these actions, that I can see.

Did these redacted sentences need to be kept classified for 60 years? Of course not. And by releasing them in full, the Department of Energy explicitly agrees that these transcripts contain nothing classified as of today. But they weren’t being hoarded for decades because of their lasting security relevance — they were just forgotten about. These volumes probably could have been fully declassified at least as early as 1992, and probably would have, had the declassification effort not gotten shelved.

Still, it is important that they are finally released. Even a negative result is a result, and even an empty archive can tell us something positive. Knowing that the un-redacted transcripts contain nothing that would either exculpate, nor incriminate, J. Robert Oppenheimer is itself something to know. Secrecy does not just hide information: it creates a vacuum into which doubt, paranoia, fear, and fantasy are harbored. Removing the secrecy here has, at least, removed one last veil and source of uncertainty from the Oppenheimer affair.

General Groves’ secret history

Friday, September 5th, 2014

The first history of the Manhattan Project that was ever published was the famous Smyth Report, which was made public just three days after the bombing of Nagasaki. But the heavily-redacted Smyth Report understandably left a lot out, even if it did give a good general overview of the work that had been done to make the bomb. Deep within the secret files of the Manhattan Project, though, was another, classified history of the atomic bomb. This was General Leslie Groves' Manhattan District History. This wasn't a history that Groves ever intended to publish — it was an internal record-keeping system for someone who knew that over the course of his life, he (and others) would need to be able to occasionally look up information about the decisions made during the making of the atomic bomb, and that wading through the thousands of miscellaneous papers associated with the project wouldn't cut it.

Manhattan District History - Book 2 - Vol 5 - cover

Groves' concern with documentation warms this historian's heart, but it's worth noting that he wasn't making this for posterity. Groves repeatedly emphasized both during the project and afterwards that he was afraid of being challenged after the fact. With the great secrecy of the Manhattan Project, and its "black" budget, high priority rating, and its lack of tolerance for any external interference, came a great responsibility. Groves knew that he had made enemies and was doing controversial things. There was a chance, even if everything worked correctly (and help him if it didn't!), that all of his actions would land him in front of Congress, repeatedly testifying about whether he made bad decisions, abused public trust, and wasted money. And if he was asked, years later, about the work of one part of the project, how would he know how to answer? Better to have a record of decisions put into one place, should he need to look it up later, and before all of the scientists scattered to the wind in the postwar. He might also have been thinking about the memoir he would someday write: his 1962 book, Now it Can Be Told, clearly leans heavily on his secret history in some places.

Groves didn't write the thing himself, of course. Despite his reputation for micromanagement, he had his limits. Instead, the overall project was managed by an editor, Gavin Hadden, a civil employee for the Army Corps of Engineers. Individual chapters and sections were written by people who had worked in the various divisions in question. Unlike the Smyth Report, the history chapters were not necessarily written near-contemporaneously with the work — most of the work appears to have been started after the war ended, some parts appear to have not been finished until 1948 or so.

General Groves not amused

In early August 1945 — before the bombs had been dropped — a guide outlining the precise goals and form of the history was finalized. It explained that:

Tho purpose of the history is to serve as a source of historical information for War Department officials and other authorized individuals. Accordingly, the viewpoint of the writer should be that of General Groves and the reader should be considered as a layman without any specialized knowledge of the subject who may be critical of the Department or the project.

Which is remarkably blunt: write as if Groves himself was saying these things (because someday he might!), and write as if the reader is someone looking for something to criticize. Later the guide gives some specific examples on how to spin problematic things, like the chafing effect of secrecy:

For example, the rigid security restrictions of the project in many cases necessitated the adoption of unusual measures in the attainment of a local objective but the maintenance of security has been recognized throughout as an absolute necessity. Consequently, instead of a statement such as, "This work was impeded by the rigid security regulations of the District," a statement such as, "The necessity of guarding the security of the project required that operations be carried on in — etc." would be more accurate.1

This was the history that Groves grabbed whenever he did get hauled in front of Congress in the postwar (which happened less than he had feared, but it still happened). This was the history that the Atomic Energy Commission relied upon whenever it needed to find out what its predecessor agencies had done. It was a useful document to have around, because it contains all manner of statistics, technical details, legal details, and references to other documents in the archive.

The Manhattan District History became partially available to the general public in 1977, when a partial version of it was made available on microfilm through the National Archives and University Publications of America as Manhattan Project: Official History and Documents. The Center for Research Libraries has a digital version that you can download if you are part of a university that is affiliated with them (though its quality is sometimes unreadable), and I've had a digital copy for a long time now as a result.2 The 1977 microfilm version was missing several important volumes, however, including the entire book on the gaseous diffusion project, a volume on the acquisition of uranium ore, and many technical volumes and chapters about the work done at Los Alamos. All of this was listed as "Restricted" in the guide that accompanied the 1977 version.3

I was talking with Bill Burr of the National Security Archive sometime in early 2013 and it occurred to me that it might be possible to file a Freedom of Information Act request for the rest of these volumes, and that this might be something that his archive would want to do. I helped him put together a request for the missing volumes, which he filed. The Department of Energy got back pretty promptly, telling Bill that they were already beginning to declassify these chapters and would eventually put them online.

The DOE started to release them in chunks in the summer of 2013, and got the last files up this most recent summer. You can download each of the chapters individually on their website, but their file names are such that they won't automatically sort in a sensible way in your file system, and they are not full-text searchable. The newly-released files have their issues — a healthy dose of redaction (and one wonders how valuable that still is, all these years — and proliferations — later), and some of the images have been run through a processor that has made them extremely muddy to the point of illegibility (lots of JPEG artifacts). But don't get me started on that. (The number of corrupted PDFs on the NNSA's FOIA website is pretty ridiculous for an agency that manages nuclear weapons.) Still, it's much better than the microfilm, if only because it is rapidly accessible.

But you don't need to do that. I've downloaded them all, run them through a OCR program so they are searchable, and gave them sortable filenames. Why? Because I want people — you — to be able to use these (and I do not trust the government to keep this kind of thing online). They've still got loads of deletions, especially in the Los Alamos and diffusion sections, and the pro-Groves bent to things is so heavy-handed it's hilarious at times. And they are not all necessarily accurate, of course. I have found versions of chapters that were heavily marked up by someone who was close to the matter, who thought there were lots of errors. In the volumes I've gone the closest over in my own research (e.g. the "Patents" volume), I definitely found some places that I thought they got it a little wrong. But all of this aside, they are incredibly valuable, important volumes nonetheless, and I keep finding all sorts of unexpected gems in them.

You can download all of the 79 PDF files in one big ZIP archive on Archive.org. WARNING: the ZIP file is 760MB or so. You can also download the individual files below, if you don't want them all at once.

What kinds of gems are hidden in these files? Among other things:

And a lot more. As you can see, I've drawn on this history before for blog and Twitter posts — I look through it all the time, because it offers such an interesting view into the Manhattan Project, and one that cuts through a lot of our standard narratives about how it worked. There are books and books worth of fodder in here, spread among some tens of thousands of pages. Who knows what might be hidden in there? Let's shake things up a bit, and find something strange.


Below is the full file listing, with links to my OCR'd copies, hosted on Archive.org. Again, you can download all of them in one big ZIP file by clicking here, (760 MB) or pick them individually from below. Items marked with an asterisk are, as far as know, wholly new — the others have been available on microfilm in one form or another since 1977. Read the full post »
