Louis Hempelmann was J. Robert Oppenheimer’s physician and close friend. In this interview, he discusses the hierarchy at Los Alamos, what it was like to work with Kitty Oppenheimer, and Kitty and Robert’s relationship. He recalls his interactions with Oppie, Enrico and Laura Fermi, and Edward Teller, and the parties that Oppenheimer and others used to throw at Los Alamos. Hempelmann remembers driving to Trinity Site with George Kistiakowsky and the high explosives—on Friday the 13th.
David Bohm was an American theoretical physicist who would later become a citizen of the United Kingdom. After finishing his undergraduate degree at the Pennsylvania State University in 1939, Bohm arrived at the University of California, Berkeley on a seemingly meteoric rise. However, during this same period he became affiliated with the Communist Party, which would ultimately undermine his chances for success in the United States. After being investigated by the House Un-American Activities Committee in 1950, he was forced to continue his study of physics in other countries. In this interview, he discusses his time at Berkeley before and during the war and the left-wing movement at Berkeley. He describes his former mentor J. Robert Oppenheimer as a brilliant mind with occasional charisma that made him a strong administrator.
