Committee on Uranium
Participants || Resources || Visuals || Course Hub 

In 1939 a group of U.S. scientists and military experts met to decide whether (and how) to pursue research on a possible atomic bomb. In this project, each participant will assume the role of a historical figure who was there and we will recreate the historical event -- and reach our own decision.

Background: In 1939, Alexander Sachs carried a letter from physicists Albert Einstein and Leo Szilard to then President of the United States, Franklin Roosevelt, advising him of the theoretical potential to build a weapon based on the release of nuclear energy. No one actually knew, however, whether such a functional device could ever be built. Controlled sustained nuclear fission was still only a dim theoretical possibility. The U.S. was not then at war with Germany, but the possibility loomed. President Roosevelt asked Lyman Briggs, Director of the U.S. Bureau of Standards (then our national laboratory of physics), to convene a committee to advise him on this matter. "The Advisory Committee on Uranium" met on Sat., October 21, 1939 in Washington, D.C.

Note: We are not trying to re-enact the actual decision that was made historically. Rather, we are using the history as a scenario for making our own recommendation, based on information that was available at the time. Afterwards, we will compare our decision with the actual history and try to interpret any similarities and differences.

Participants at this meeting:

  • Lyman Briggs, Director, U.S. Bureau of Standards (Chair)
  • Leo Szilard, physicist --
  • Eugene Wigner, physicist --
  • Richard B. Roberts, physicist --
  • Alexander Sachs, economist --
  • Edward Teller, physicist (designated representative for Enrico Fermi & Merle Tuve) --
  • Merle Tuve (invited, but did not attend) --
  • Enrico Fermi (invited, but did not attend) --
  • Keith F. Adamson, Lt. Col., U.S. Army --
  • Gilbert C. Hoover, Comm., U.S. Navy --

Guiding Questions:

  • Can nuclear power actually be harnessed?
  • Is building a bomb a realistic enough possibility to consider it seriously at this point?
  • Should research proceed on the assumption that one will be built, if feasible?
  • Should the international political scene be relevant to the pursuit of science?
  • What research on nuclear physics is now most important?
  • How much will it cost, and who will fund it?
  • Will the research be kept secret?


Each person must prepare a concentrated written summary of their argument --in first person as their character (~1250 wds/person, excluding references and visuals) and present a 3-minute summary in class (without reading). Each contribution should include:

  • at least two references to contemporary documents.
  • at least one visual image appropriate to the argument (to use in class presentation)
  • Use footnotes or appendix to add your perspective or commentary, where it differs from your character.
    Evaluation will be based on how deeply you reconstruct the historical context and arguments and your contribution to class understanding on the general questions above. Your position statement is due (electronically) November 7, 2004 and is worth 20% of the course grade (15% for HSci 3815).
