Oral Histories

Dr. James Hershberg is a leading scholar on Cold War history. In this interview, Hershberg explains in great detail the complex history of the Manhattan Project. He explores the scientific and political climate leading up to the Project, the symbolism and implications of the atomic bomb, and the feelings of various Manhattan Project scientists. He also explains the debate over developing the hydrogen bomb, different historical perspectives for explaining the Manhattan Project, James B. Conant’s recollections of witnessing the Trinity Test, and U.S./Soviet Union relations throughout the Cold War. Hershberg ends the interview by discussing how various nations have become nuclear powers, and how the Cold War and nuclear history are relevant today.

Hans Bethe was a German-American physicist and Nobel Prize winner who was head of the Theoretical Division at Los Alamos. He played an important role in the development of the hydrogen fusion bomb. In this interview, Bethe discusses the decision to develop the H-bomb in a starkly different context compared to the A-bomb. He recalls the debate over MIRV, the rise of the nuclear race, and missed opportunities to promote nuclear nonproliferation, including the Cuban Missile Crisis and Bernard Baruch’s plan.

Marshall Rosenbluth was an American physicist who worked in the theoretical division at Los Alamos from 1950 to 1956. In this interview, Rosenbluth addresses the theoretical issues involved in designing both the atomic and hydrogen bombs. He discusses how the pressure to create a nuclear bomb before the Soviet Union affected work in the laboratory, especially in performing and checking calculations. Rosenbluth also recounts his experiences during the nuclear weapons tests at Los Alamos and Bikini Atoll. He recalls the roles of top scientists, like Edward Teller, Hans Bethe, Enrico Fermi, and Carson Mark, in the building of the hydrogen bomb. He also explains how funding and other external factors affected the hydrogen bomb’s design.
