  Alex Wellerstein is a historian of science and nuclear weapons and a professor at the Stevens Institute of Technology. He is also the creator of the NUKEMAP. This blog began in 2011. Follow him @wellerstein.bsky.social.

  

  Want more nuclear secrecy content? Check out my book:
  Restricted Data: The History of Nuclear Secrecy in the United States (University of Chicago Press, 2021).

  I have a NEW book from HarperCollins (2025) — a brand-new take on Truman and the bomb:
  THE MOST AWFUL RESPONSIBILITY:
  Truman and the Secret Struggle for Control of the Atomic Age

  

  I also have a NEW blog/newsletter which updates much more regularly:
  
  Doomsday Machines
  Post-Apocalyptic Road Trips, End of the World-Building, and Interesting Times. A blog about how we think and have thought about end of the world, in both fact and fiction.
