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.

Neglected Niigata

Friday, October 9th, 2015

Last week I gave a talk at a conference on “Nuclear Legacies” at Princeton University on Kyoto and Kokura, the two most prominent “spared” targets for the atomic bomb in 1945. The paper grew out of ideas I first put to writing in two blog posts (“The Kyoto misconception” and “The luck of Kokura“), and argues, in essence, that looking closely at these targeted-but-not-bombed cities gives us new insights into both the bombings of Hiroshima and Nagasaki. Importantly, they both end up highlighting different aspects of what Truman did and did not know about the atomic bombings — my thesis is that on several important issues (notably the nature of the targets and the timing of the bombs), Truman was confused.

The basic stories of how Kyoto and Kokura avoided the bomb are known (though, as I argue, the devil is in the details). Kyoto was the military’s first choice for an atomic bombing target, but vetoed by the Secretary of War and eventually Truman himself. Kokura was the primary target for the second atomic bombing mission, but the target was obscured by clouds, smoke, and/or haze, and so the secondary target, Nagasaki, was bombed instead.

There was another target on the atomic bombing list, however, one the literature almost completely ignores: Niigata.

Niigata had been on the list of possible targets for quite some time. It was a port city in north-west Honshu. The notes of the second Target Committee meeting described it thusly:

Niigata – This is a port of embarkation on the N.W. coast of Honshu. Its importance is increasing as other ports are damaged. Machine tool industries are located there and it is a potential center for industrial despersion [sic]. It has oil refineries and storage. (Classified as a B Target)1

That’s not a very enthusiastic write-up, and it’s not surprising that it was the lowest priority recommended target (and had the lowest classification rating by the US Army Air Forces). It was the target about which they had the least to say.

Groves got a report on  In early July 1945, Groves received “New Dope on Cities” that included a fact-sheet on Niigata. It identified several useful industries, but it is much less exciting than the write-ups for Kyoto, Hiroshima, or Kokura. Niigata was noted as:

Principally important for aluminum, machine tools and railroad equipment. Also located here are small oil refineries, several chemical plants and woodworking plants. The harbor has been much improved and has extensive storage and trans-shipment facilities.2

It’s hard not to yawn at this. By contrast, Kyoto was written about as a major city of military and industrial importance, and Kokura was “one of the largest arsenals in Japan.” So they weren’t that enthusiastic about Niigata. But still, it was on the short-list of targets, and it was on the list of targets “reserved” from conventional bombing (unlike Nagasaki).3 Why didn’t it end up on any of the missions, even as a backup target? (The first bomb’s targets were, Hiroshima, Kokura, and Nagasaki, in that order of priority; the second bomb’s targets were Kokura and Nagasaki, in that order.)

The five atomic targets of 1945, with distances between each other and relevant bases indicated.

The easiest and most plausible answer as why it wasn’t on those orders is a geographical one. Niigata was some 440 miles away from Hiroshima, the other closest target on the final list. By contrast, the other three main targets (Hiroshima, Kokura, Nagasaki) were all around 100-200 miles from one another. When you’re flying a B-29 carrying a five-ton bomb, every mile starts to matter in terms of fuel, especially when the trip from Tinian is going to be another 1,500 miles, and ditto the trip back (though Okinawa was only about 470 miles from Nagasaki). Truman’s memoirs say that Niigata “had been ruled out as too distant” for the first two raids. While I am inherently suspicious of postwar memoirs (they tend to smooth out and rationalize what was at the time a rather chaotic series of events and choices), and especially Truman’s, this sounds plausible.4

So we don’t talk about Niigata. Would it have been bombed next, if future atomic bombing runs were going to happen? Truman claimed later that this was definitely the case, but we really don’t know whether they would have continued to use them on cities, or whether they would have tried to use them “tactically.” Though there were a number of ideas floating around for what a “third shot” might look like, none of them ever got to a stage of planning that in retrospect looks official. So we just don’t know. I suspect that if they were going to bomb another city, the next one would be Kokura. They had that mission well-planned out (it was, after all, the initial choice for the Nagasaki bombing), and its target profile would make “good use” of the specific types of forces the atomic bomb was capable of (very heavy pressures near ground zero, lighter pressures around — great for a city with a military/industrial arsenal at the center of it and surrounded by workers’ housing), and for a President who was beginning to tire of the loss of civilian life, bombing a military arsenal would look a lot more like what he imagined the atomic bomb was being used for than the horror visions of dead women and children that he was reading about in the newspapers.

There were those at the time (notably General Carl Spaatz) who argued for using the next bomb on Tokyo, but I doubt they would have done that. Killing the Emperor would have severely complicated the surrender process (because it would have set off a crisis of political succession) and the city was too bombed-out for the bomb to look very impressive. My basis for thinking this reasoning would matter to them is based on target discussions prior to the bombing of Hiroshima and Nagasaki, though; it is pretty hard to say how they thought about their original target criteria after the bombs were used.

(One of my messages in my talk at Princeton, incidentally, is that scholars of this subject need to be very explicit about where they are making interpretive leaps. We have a few very useful “data points” in terms of documents, recollections, interviews. We are all trying to weave a plausible narrative through those data points. Many writers on this subject smooth over these jumps with “probably,” “it is likely,” “it seems plausible,” and other elisions. I get why they do it — there is an impulse to make things look neat and tidy, and it can wreck a story to constantly point out where you are making a huge assumption. But it often makes this literature look much more “concrete” than it actually is, and the more I dig into the documents and footnotes, the more I find that there are very important and conspicuous gaps in our knowledge of these events, and there are multiple, radically-different narratives consistent with the “data.” So I think we ought to foreground these, both for our readers, and ourselves — the gaps are not things to be embarrassed about, but challenges to be embraced.)

But to return to Niigata: so why was it on the list in the first place, if it wasn’t close to any of the other targets? Ah, but it wasn’t very far from Kyoto, Tokyo, and Yokohama — a few of the other potential targets discussed around the time Niigata was added to the list. (Niigata is 270 miles from Kyoto, 170 miles from Tokyo and Yokohama.) So in that sense, Niigata tells us something else about the removal of Kyoto: if Kyoto had been on the target list, would Niigata have been one of the backup targets, to be used if the weather was better there than Kyoto or Hiroshima? This is just speculation, but that seems plausible to me. If that’s the case, then taking Kyoto off the list spared two cities, not just one. And Niigata’s inclusion possibly a relic of an earlier targeting debate, one made less relevant by August of 1945.

Of course, in this case, “sparing” is a zero-sum game: one city’s reprieve was another’s doom. Just ask Nagasaki, a city that no doubt would have preferred circumstances that would have given it Niigata’s relative lack of attention from historians.

Did Lawrence doubt the bomb?

Friday, September 4th, 2015

Ernest O. Lawrence was one of the giants of 20th-century physics. The inventor of the “cyclotron,” a circular particle accelerator, Lawrence ushered in an era of big machines, big physics, big budgets — Big Science, in short. And that came with ups and downs. I’ve recently finished a review for Science of Michael Hiltzik’s new Lawrence biography, Big Science: Ernest Lawrence and the Invention that Launched the Military-Industrial Complex. The full review is online but behind a paywall (if you want a copy, get in touch with me), but I am allowed to post the unedited version that I originally submitted, which in this case is about twice the size of the printed one, so maybe it’s interesting as an essay in its own right (so I may flatter myself). I found it hard to cram the story of Lawrence, and this book, in a thousand words (and brevity has never been my strength), because there is just so much going on and worth commenting on.

My wonderful Stevens STS colleague Lee Vinsel had a review in last week's issue of Science as well.

Lawrence featured early into my education. I was an undergraduate at UC Berkeley, which means I was in Lawrence country. His laboratory literally perches above the campus, looking down on it. In various buildings on campus, it is not uncommon to come across a large portrait of the man. And any geeky child in northern California visits the Lawrence Hall of Science numerous times in the course of their education.

As a budding historian of science, what I found so incongruous about Lawrence was the way in which he embodied something of a paradox at the heart of particle physics. High-energy particle physics is for the most part a pretty “pure” looking form of science, trying to pull-off very elegant experiments with the most abstract of physical entities, and making the experimental evidence jibe with the theoretical understandings. When people want to point to evidence of objectivity in science, or to the places where theory gets vindicated in a very elegant way, they point to particle physics. And yet, to do these experiments, you often need big machines. Big machines require big money. Big money gets you into the realm of big politics. And so this very elegant, above-it-all form of science ends up getting tied to the hip of the military-industrial complex during and after World War II. How ironic is that?

As you can pick up from both the published and draft review, I had mixed feelings about Hiltzik’s book. I think people who have never read anything about Lawrence before will find it interesting though potentially confusing, because it bounces around as a genre. One can’t really tell what Hiltzik thinks about Lawrence. Half of the time Hiltzik seems to want to make him out to be the Great Hero of 20th century science. (Sometimes this gets hyperbolic — Lawrence was a big character, to be sure, but he was still of his time, and it does some historical injustice to claim that everything related to Big Science necessarily is laid at his door. To claim that Big Science was “a solitary effort,” as Hiltzik does, is as self-contradictory as it is untrue.) The other half of the time, though, Hiltzik is pointing out what a huge jerk he could be, how bad of a scientist he could be, and how he sullied himself with some of the worst sorts of political engagements during the Cold War. Everyone gets on Edward Teller for being a far-right, pro-nuke, anti-Communist jerk, but even Teller thought Lawrence could be an extremist when it came to these things.

This ambivalent mix — Lawrence as great, Lawrence as terrible — never gets resolved. One could imagine it being talked about as two sides of the same coin, or some sort of synthetic whole emerging out of these two perspectives. But it just doesn’t happen in the book. In my own mind, this is the somewhat Faustian result of Lawrence’s “cult of the machine” (as I titled my review), where the Bigness required for his science ended up driving extremes in other parts of his life and politics as well.

Serious historians of 20th-century physics will find little new in Hiltzik’s book, either in terms of documentation or analysis. He relies heavily on secondary sources and the archival sources he does consult are the standard ones for this topic (e.g. the Lawrence papers at UC Berkeley). The book also contains several avoidable errors of a mostly minor sort, but the kinds of misconceptions or misunderstandings that ought to have been caught before publication (some of which I would like to imagine would jump out to anyone who had read a few books on this subject already). I did not mention these in the formal review, because there was really not enough space to warrant it, and the book never hinged on any of these details, but still, it seems worth noting in this more informal space.1

That aside, the book reminded me of one of the strangest aspects of Lawrence’s relationship with the bomb — whether he thought it was a good idea to drop one on Japan without a warning. As I’ve discussed before, the question of whether a “demonstration” should be made prior to shedding blood with the bomb was a controversial one on the project. A Scientific Panel composed of J. Robert Oppenheimer, Arthur H. Compton, Enrico Fermi, and Ernest Lawrence were asked to formally consider the question in the June of 1945. They formally recommended that the bomb be dropped on a city without warning: “we can propose no technical demonstration likely to bring an end to the war; we see no acceptable alternative to direct military use.”

But there’s potentially more to it than just this. Case in point: in the archives, one finds a letter from Karl K. Darrow to Ernest Lawrence, dated August 9th, 1945. Darrow was a friend of Lawrence’s, and a fellow physicist, and a noted popularizer of science in his day. And this is an interesting time to be writing a letter: Hiroshima has already occurred and is known about, and Nagasaki has just happened (and Darrow may or may not have seen the news of it yet), but the war has not ended. This period, between the use of the bomb and the cessation of hostilities, is a very tricky one (a topic Michael Gordin has written a book on), because the meaning of the atomic bomb had not yet been cemented. That is, was the atomic bomb really a war-ending weapon? Or just a new way to inflict mass carnage? Nobody yet knew, though many had uncertain hopes and fears.

August 9th is also a tricky period because this is around the time in which the first casualty estimates from Hiroshima were being received, by way of the first Japanese news stories on the bombing. They were much higher than many of the scientists had thought; Oppenheimer had estimated them to be around 20,000, and they were hearing reports of 60,000 or higher. For some, including Oppenheimer, they saw this as a considerable difference with respects to how comfortable they felt with the attacks.

This context is relevant to making sense of the Darrow letter. The archival document is hard to read, and in some places illegible, so I’ve included a transcription that I typed up from the best of my reading of it. The import of it is pretty easy to take away, though, even with a few phrases being hard to read. Here is an excerpt of the key parts:

Dear Ernest:

This is written to you to put on the record the fact that you told me, on August 9, 1945, that you had presented to the Secretary of War by word of mouth the view that the “atomic bomb” ought to be demonstrated to the Japanese in some innocuous but striking manner before it should be used in such a way as to kill many people. You made this presentation in the presence of Arthur Compton, Fermi, Oppenheimer and others, and spoke for about an hour. The plan was rejected by the Secretary of War on the grounds that (a) the number of people to be killed by the bomb would not be greater in order of magnitude than the number already killed in the fire raids, and (b) an innocuous demonstration would have no effect on the Japanese. […]

I think that it is not far-fetched nor absurd to conjecture that in time to come, people will be saying “Those wicked physicists of the ‘Manhattan Project’ deliberately developed a bomb which they knew would be used for killing thousands of innocent people without any warning, and they either wanted this outcome or at least condoned it. Away with physicists!” It will not be accepted as an excuse that they may have disapproved in silence. We do not excuse the German civilians who accepted Buchenwald while possibility disapproving in silence.

I think that if the war ends today or tomorrow or next week, this sort of criticism will not be heard for a while, and yet it will be heard eventually — and particularly it will be heard if at a time should come when some other power may be suspected of planning to use the same device on us. In other words, if the use of this weapon without forewarning has really brought quick victory, this fact will delay but will not indefinitely prevent the emergence of such an opinion as I have suggested. It may then be of great value to science, if some scientist of very great prominence has already said that he tried to arrange for a harmless exhibition of the powers of the weapon in advance of its lethal use.2

There is a lot going on in this letter. First, it makes it clear that Lawrence and Darrow had a discussion about the demonstration matter right around the time of the Nagasaki bombing. It is also clear that Darrow came away with the impression that Lawrence was deeply unsure about the logic of bombing without warning. Now the amount of pontificating by Darrow makes it seem like Darrow might be reading into what Lawrence told him more than Lawrence said — Darrow’s concerns are not necessarily Lawrence’s concerns. But it does seem clear that Darrow thinks he is setting something into the record that might be useful later, and that even if the war ended soon, there were going to be doubts to be contended with, and the fact that Lawrence was worried about using the bomb might somehow be exculpatory.

Darrow’s letter was received on August 10th (so it is stamped), but it isn’t clear when Lawrence read it. He did not reply until August 17th, 1945, by which point hostilities with Japan had ended. This is a big thing to point out: the Darrow-Lawrence conversation, and original letter, took place at a time when it wasn’t clear whether the bombs would actually be credited with ending the war. By August 17th, Japan had already pressed for an end of the war and had credited the atomic bomb in part with their defeat.3 If Lawrence ever did have doubts, they were gone by August 17th:

Dear Karl:

In reply to your letter of August 9th, you have the facts essentially straight, excepting that I didn’t believe I talked on the subject of the demonstration of the bomb as long as an hour. I made the proposal briefly in the morning session of the Secretary of War’s committee, and during luncheon Justice Byrnes, now Secretary of State, asked me further about it, and it was discussed at some length, I judge perhaps ten minutes.

I am sure it was given serious consideration by the Secretary of War and his committee, and gather from the discussion that the proposal to put on a demonstration did not appear desirable […] Oppenheimer felt, and that feeling was shared by Groves and others, that the only way to put on a demonstration would be to attack a real target of built-up structures. 

In view of the fact that two bombs ended the war, I am inclined to feel they made the right decision. Surely many more lives were saved by shortening the war than were sacrificed as a result of the bombs. […]

As regards criticism of science and scientists, I think that is a cross we will have to bear, and I think in the long run the good sense of everyone the world over will realize that in instance, as in all scientific pursuits, the world is better as a result.4

To me, this letter reads as something of a kiss-off to Darrow’s doubts — and maybe to doubts Lawrence himself might have once held. Darrow recalls Lawrence telling him it was an hour-long discussion, and a major conflict between the soulful Lawrence and the unfeeling others. In Lawrence’s post-victory recollection, it becomes a 10-minute talk, duly taken seriously but not that hard of a question to answer, and in the end, the ends justified the means, neat and tidy.

One can take guesses based on rings, handedness, etc., but the copy of the scan that I have has sufficient resolution that you can read the dials, which I think resolves the question.

So where lies the truth? Was Lawrence a doubter at the time of the Nagasaki bombing, only to lose all doubts after victory? Was Darrow projecting his own fears onto Lawrence at their meeting? I suspect something in between — with a second bomb so rapidly dropped after the first, Lawrence and Darrow might have both been wondering if these weapons would really end the war (much less all war), if they weren’t just a new-means of old-fashioned mass incineration. Maybe Lawrence exaggerated, or gave an exaggerated impression, of his debate over the demonstration.

One interesting piece is that the story of “doubts” can, as Darrow implied, be made exculpatory without necessarily calling into question the wisdom of the bombing. That is, if the story is about how the scientists really didn’t want to use the bomb, but couldn’t see a better way around it, then you get (from the perspective of the scientists involved) the best of both worlds: they still have souls, but they also have justification. This is how Arthur Compton presents the meeting in his 1956 book, Atomic Quest, which takes more the Darrow perspective of a fraught Scientific Committee, Ernest Lawrence as the final hold-out, but with “heavy hearts” they recommend direct military use.5

J. Robert Oppenheimer, for his part, later said he had “terrible” moral scruples about the dropping of the bomb, of killing at least 70,000 people with the first one, though, notably, he never said he regretted doing it. He did, however, think that physicists had “known sin” and required an active role in future policy regarding these new weapons, if only to keep the world from blowing itself up. Lawrence parted ways with his former friend and colleague after World War II, remarking that “I am a physicist and I have no knowledge to lose in which physics has caused me to know sin” and chastising those scientists (like Oppenheimer) who thought that they ought to be getting involved with policymaking, as opposed to research — or bomb-building.

If Lawrence had doubts, he left by the wayside once the promise of victory was in the air, and he happily and seemingly without misgivings hitched himself permanently to the burgeoning military-industrial complex. He was part of the anti-Oppenheimer conspiracy that led to the 1954 security hearing, he worked closely with Edward Teller and Lewis Strauss to attempt to scuttle attempts at test bans and moratoriums, he pushed for greater quantities of bigger bombs, he sold out colleagues and friends, participating in McCarthyist purges with gusto. He was also the inventor of the cyclotron, a physicist of great importance, and one of the creators of the Big Science approach to doing research. These are not incompatible takes on a complex human being — but when we celebrate the scientific accomplishments, we do history poorly if we forget the parts that are arguably less savory.

Notes
  1. A short list of the serious errors that jumped out at me follows. Page 227: Hiltzik says that Hanford (as a site) could only produce half a pound of plutonium every 200 days. That this is a misunderstanding should be pretty obvious given that they managed to come up with 27 lbs of it (for Trinity and Fat Man) by late July 1945 despite starting B-Reactor in late 1944. I don’t know where the 200 days figure comes from, but the Hanford reactors could get 225 grams (about half a pound) of plutonium for every ton of uranium they processed, and each reactor was designed to process 30 tons of uranium per month at full power (though it took several months for the plutonium to be extracted from any given ton of exposed uranium). Because there were three reactors, that means that optimally Hanford could produce about 20 kg (45 lbs) of plutonium per month. In practice they did less than that, but half a pound every 200 days is just wrong, and if true would have made two of the World War II bombs impossible. Page 292: The book gets the information about the Trinity core geometry wrong — it says it is a hollow shell that was “crushed into a supercritical ball.” Rather, the Christy core was a mostly solid core (there was a small hole for the initiator) whose density was increased by the high explosives. Hollow shell designs were considered, and were later used in the postwar, but the wartime devices did not use them. This is one of those errors that won’t die — often repeated despite a wealth of evidence to the contrary. Page 386: Hiltzik refers to the Soviet test Joe-4/RDS-6s as a “fizzle.” This is incorrect terminology and implies that it did not achieve its target yield. It was not a staged thermonuclear weapon, but it was not a fizzle — it did what it was supposed to do, and was not a disappointment in any way. Page 405: Hiltzik, perhaps by reading too much Ralph Lapp (who was very smart but sometimes got things wrong), doesn’t seem to understand how the so-called “clean bomb” would have worked. The higher the proportion of the weapon that comes from fusion reactions as opposed to fission reactions, the smaller the amount of fallout that would result. The contamination power of a weapon is not related to its total yield so much as its fission yield. The area of contamination does relate to the yield (so a 10 megaton weapon with only 1% of its yield from fission does spread those fission products over a wide area), but the intensity of the contamination does not (the level of radiation would be extremely low compared to a “dirty” hydrogen bomb that derived at least half of its power from fission). One can object that the “clean bomb” was at best a cleaner bomb, and doubt both its wisdom and the sincerity of its proponents, but the idea itself was not a hoax. Page 416: Hiltzik says that Hans Bethe “flatly refused” to join the hydrogen bomb work. This is not correct. Bethe initially refused, and then later joined the thermonuclear project at Los Alamos and made several important contributions (to the degree that he is sometimes referred to as the “midwife” of the hydrogen bomb). Bethe’s wavering position on this is very aptly discussed in S.S. Schweber’s In the Shadow of the Bomb: Oppenheimer, Bethe, and the Moral Responsibility of the Scientist. There are a few other nitpicks (e.g. saying that “the test ranges remained silent” from 1958-1961… only true if you ignore France), but those are the ones that really stood out as outright errors. The most irritating misrepresentation (not strictly a factual error so much as an omission) is the fact that while Lawrence’s Calutrons were indeed an important part of the overall enrichment system used to make the fuel for the Hiroshima bomb (though not the only part), they were shut down in the early post war because they were not as efficient as the gaseous diffusion method. One would not get that impression from Hiltzik’s book, and it is relevant inasmuch as evaluating the importance of Lawrence’s method to the war — it was a useful stop-gap, but it was not a long-term solution.

Hiroshima and Nagasaki at 70

Friday, August 21st, 2015

This month marked the 70th anniversary of the atomic bombings of Hiroshima and Nagasaki, and the cessation of hostilities in World War II. Anniversaries are interesting times to test the cultural waters, to see how events get remembered and talked about. I was exceptionally busy this summer, doing my part to try to participate in the discourse about these events. In case you missed them and wished you had not, here are a few of my appearances:

I also published a second blog post with the New Yorker on the often-overlooked second use of the atomic bomb: “Nagasaki: The Last Bomb.” I am proud of it as a piece of writing, as I was really trying to pull off something deliberate and subtle with it, and feel that I somewhat accomplished that.

New Yorker - Nagasaki - The Last Bomb

On this latter piece, I would also like to say that very little of what I wrote would come as a surprise to historians, though the particular arrangement of Nagasaki-as-JANCFU (that is, with an emphasis on the less-than-textbook aspects of the operation, as a herald of the later chaotic possibilities of the nuclear age) is usually under-emphasized. We tend to lump Hiroshima and Nagasaki together when we talking about the atomic bombings during World War II, and I think they should probably be separated out a bit in terms of how we regard them. The first use of the bomb, at Hiroshima, was in many ways a very straightforward affair, both in terms of the strategic and ethical considerations, and the tactical operation. Whether one agrees with the strategic and ethical considerations is a separate matter, of course, but a lot of thought went into Hiroshima as a target, and into the first use of the bomb. Nagasaki, by contrast, was less straightforward on all counts — less thought-out, less justified, and was very nearly a tactical blunder. For me, it reflects on the very real dangers that can occur when human judgment gets mixed with the extremely high stakes that come with weapons as powerful as these. Any bomber crew can have a mishap of a mission, but when that mission is nuclear-armed, the potential consequences multiply.

The one notable exception to the “very little would come as a surprise to historians” bit in this piece is that Nagasaki was never put on the “reserved” list. For whatever reason, the idea that both Hiroshima and Nagasaki were “reserved” from conventional bombing is very commonly repeated, but it is just not true. The final “reserved” list contained only Kyoto, Hiroshima, Kokura, and Niigata. Aside from the fact that no documentation exists of Nagasaki being put on the list (whereas we do have such documentation for the others), we also have the documentation actively rescinding the “reserved” status for Hiroshima, Kokura, and Niigata, so that they could become formal atomic targets.1

Detail from a damage map of Nagasaki, produced by the United States Strategic Bombing Survey, 1946. I have the original of this in my possession. I find this particular piece of the map quite valuable to examine up close — one gets a sense of the nature of the area around "Ground Zero" very acutely when examining it. There were war plants to the north and south of the detonation point, but mostly the labeled structures are explicitly, painfully civilian (schools, hospitals, prisons). Click to enlarge.

Here is a not-great photo of the whole map, to compare it with, and here is a detail of the legend. At some point, when finances allow, I will get this framed for my office, but it is quite large and not a cheap endeavor.

John Coster-Mullen’s book provided a lot of documents and details about the bombing run. One thing I appreciate about John is his dedication to documentation, even though his views on the meaning of the history are not always the same as mine. I thoroughly believe that rational people can look at the same facts and come up with different narratives and interpretations — the trick, of course, is to make sure you are at least getting the facts right.2

It would be interesting at some point for someone to do a scholarly analysis of the popular discourse surrounding each decade of anniversaries since the bombs were dropped. 1955 was a fairly raw time, right after McCarthyism had peaked and the hydrogen bomb had been developed. 1965 marked an outpouring of new books and revelations from those involved in the bomb project, enabled by new declassifications (allowed, in part, because of the fostering of a civilian nuclear industry) and the fact that some of the major participants (like Groves) were still alive. I have no distinct impressions of 1975 being a major anniversary year, but 1985 resulted in a lot of hand-wringing about the relationship between the birth of the nuclear age and the nuclear fears of the 1980s. 1995, of course, was the first post-Cold War anniversary and one of the “hottest” years of controversy, catalyzing around the Smithsonian’s Enola Gay exhibit controversy and the “culture wars” of the mid-Clinton administration. We are still dealing with the hyper-polarization of the narratives of the atomic bombings that became really prominent in the mid-1990s — where there were only two options available, an orthodox/reactionary view or a critical/revisionist view. The 2005 anniversary did not make a large impression on me at the time, and seemed muted in comparison with 1995 (perhaps a good thing), except for the fact that some very noteworthy scholarship made its appearance to coincide with it.

And what of 2015? There were, of course, many stories about the bombings. Nagasaki got a better representation in the discourse than usual, in no small part because Susan Southard’s Nagasaki: Life After Nuclear War received heavy promotion. (I have not read it yet.) The general discussion seemed less polarized than they have been, though I did see a fair share of hand-wringing and defending editorials pop up on my Google Alerts feed. I have speculated that I think anniversaries from this point forward will be somewhat more interesting and reflective than those in the recent past, in part because of the declining influence of American World War II veterans, who were such a strong force in the more recent ones. My (perhaps overly idealistic) hope is that our narratives of the bombings can settle into something more historically informed, more quietly reflective, and less keyed to contemporary politics than in the past.

For my part, I was impressed by the number of people online who were interested in re-creating Hiroshima on their hometowns. The featuring of NUKEMAP on the Washington Post’s Wonkblog drove an incredible amount of traffic to the site. It was one of those stories that could be essentially lifted and re-written to fit a wide variety of different cities or countries, and there were variations of the “What would happen if Hiroshima happened here?” written in dozens of languages over the days leading up to and beyond the anniversary. The result is that NUKEMAP’s traffic had an all-time high spike over 300,000 people on August 6. The traffic is a typical long-tail distribution, so in the week of August 5-12, there were well over 1 million pageviews for the NUKEMAP. There have been other spikes in the past, but none quite as big as this one.

Locations where the Little Boy bomb was "dropped," August 5-12, 2015. These are unweighted (each dot represents an indeterminate number of detonations). Here is a heatmap (capped at 1,000 detonations — the actual cap is 28,116 — to make it easier to see the broader spread) showing where repeat detonations occurred. Here is a version where I have thrown out all locations where fewer than 10 detonations took place, and scaled their size and color by repetition. Total detonations is 266,483.

Where do people nuke, when they recreate Hiroshima? Well, all over the world, not surprisingly, though the biggest single draws are New York (which is a NUKEMAP default if it cannot figure out where you probably live) and Hiroshima itself (re-creating the actual bombing). I’ve exported the log data for people using the Little Boy bomb setting (15 kiloton airbursts) for the week of August 5-12, and the maps are shown and linked to above. Obviously it correlates very heavily with both population and Internet access, but still, it is interesting.

Lastly, a week after the anniversary, what more reflection is there to be had? A new poll came out in late July of a thousand Americans, asking them what they thought about the bombings. Overall, 46% of those polled thought that the dropping of the bombs on Japan was the “right decision” to do, while 29% thought it was the “wrong decision,” and 26% said they were “not sure.” Which one can interpret in a number of ways. The feelings appear to correlate directly with age — the older you are, the more likely you think it was “right,” and the younger, with “wrong.” It also correlates with a few other factors, notably political affiliation (Republicans strongly in favor, Democrats and Independents not so much), race/ethnicity, and income. I suspect all of these variables (age, political affiliation, race/ethnicity, and income) to be pretty highly correlated in general. Separately, the gender gap is pretty extreme — men defend the bombings by a very large margin compared to women.

None of this is extremely surprising, I don’t think. But I was taken aback by another question in the same poll, a strictly factual one: “Which country was the first country to build a nuclear weapon?” Only 57% of the total polled correctly identified the United States, and it gets very depressing when one looks at how this breaks down by age. Less than half of Americans under the age of 45 could correctly identify that their country was the first country to develop nuclear weapons. I don’t really mind if a lot of people can’t identify when the first weapons were used (another question in the poll); exact years can be hard for people, especially on the spot, and the differences between the options given were not so vast that they represent much, in my view. But 23% were “not sure” who made the first bomb, 15% thought it was the USSR, and 3% thought it was China! (Almost nobody, alas, thought it was France.) This is not a minor factual error — it is a fundamental lack of knowledge about the historical composition of the world. It reflects, I suspect, the waning attention given to nuclear issues in the post-Cold War.

One last reflection: How do I, a historian of these matters, find myself thinking about Hiroshima and Nagasaki these days? Increasingly I find myself uninterested in the question of whether they were “justified” or not, which contain so much predictable posturing, the same old arguments, with very few new facts or analyses. I think the bombings were a very muddy affair from an ethical, strategic, and historical perspective, and I don’t think they fit into any simplistic view of them. I’ve come to feel my position on these could be described as an “inverse moderate,” where a moderate seeks to make everyone feel comfortable, but my goal is to make everyone feel uncomfortable. If you think this history supports some easy, straightforward interpretation, you are probably throwing out a lot of the data and filling it in with what you’d like to believe. It is complex history; it does not boil down easily.

  2. And, of course, I am not so naive to believe that “getting the facts right” is a simple or straightforward process. Indeed, contextualization of documents is a large part of understanding what the “facts” often are, and that requires narrative and interpretation, and so we end up in a somewhat circular epistemological loop. But there is a difference between people outright getting them wrong and people who are at least trying to get them right. I have been frustrated to see the number of people who still claim that the US warned the Japanese before the atomic bombings, a myth perpetuated in no small part due to shoddy citation by archivists at the Truman Library on their website.

“Nagasaki: The Last Bomb”

Friday, August 7th, 2015

This is just a quick place-holding note (a longer post on this will follow next week): I have an article up on the New Yorker’s Elements blog about the bombing of Nagasaki, which took place 70 years ago this Sunday. Check it out: Nagasaki: The Last Bomb.
