Inge-Juliana Sackmann Christy is a physicist and author. She was born in Germany in 1942 and immigrated to Canada in the 1950s. She later married physicist Robert Christy, who was an important member of the Manhattan Project. In this interview, Sackmann Christy describes details from her early life, how she met Robert Christy, the personalities of famous Caltech scientists such as Richard Feynman, and German physicists’ perspectives on the atomic bomb.
Edwin and Elsie McMillan were among the first people to arrive at Los Alamos. Edwin, who would go on to win the Nobel Prize in Chemistry, was involved in the initial selection of Los Alamos. In this lecture, Edwin describes visiting Jemez Springs and Los Alamos when he, Oppenheimer, and General Groves were deciding on the site for the weapons laboratory. McMillan also discusses his involvement in implosion research, the gun program, and recruiting scientists including Richard Feynman to the project at Princeton University. He also remembers requisitioning Harvard’s cyclotron for the Manhattan Project.
Haakon Chevalier was a French literature professor, author, and close friend of J. Robert Oppenheimer beginning at Berkeley in 1937. In this interview, Chevalier discusses aspects of Oppenheimer’s personal life, including his romantic relationships, hobbies, and religious views. He explains his own involvement in the Communist Party and Oppenheimer’s work on left-wing issues, and gives his thoughts on Oppenheimer’s security trial in 1954. Chevalier recalls first meeting Kitty Oppenheimer, and remembers her as a warm and friendly woman.
Robert Serber was an American physicist. He was recruited by J. Robert Oppenheimer to work on the Manhattan Project. Serber was tasked with explaining the basic principles and goals of the project to all incoming scientific staff. Moving to Los Alamos in 1943, he gave lectures to members of the Manhattan Project about the design and construction of the atomic bomb; these lectures came to be known as the “Los Alamos Primer.” In this interview with Martin Sherwin, Serber talks about Oppenheimer and the physics community at Berkeley before the war. He recalls Oppenheimer’s relationships with his graduate students, and his own friendship with Oppie. Serber also gives his thoughts on Oppenheimer’s relationship with Jean Tatlock and Tatlock’s psychological issues.
Mildred Goldberger was an American mathematician. She worked at the Metallurgical Laboratory at the University of Chicago during the Manhattan Project. She was married to Marvin “Murph” Goldberger, a physicist who taught at Princeton during J. Robert Oppenheimer’s tenure as Director of the Institute for Advanced Study. In this interview, she gives a glimpse into what life was like in Princeton during the 1950s-60s. She discusses her relationship with the Oppenheimer family during this period and notes the Oppenheimers’ struggles to fit in with the rest of the Princeton community.
Marvin Goldberger was President of the California Institute of Technology (Caltech) and a friend of J. Robert Oppenheimer’s from his days at Princeton, after World War II. In this interview, he talks about his and his wife’s relationships with Robert and Kitty Oppenheimer. He also discusses Oppenheimer’s reputation as a physicist and personality, as well as how Oppenheimer fit into the social scene in post-war Princeton. Goldberger recounts how he first met Oppenheimer, and gives his impressions of other Manhattan Project figures including Robert Serber and Edward Teller.
Haakon Chevalier was a French literature professor at Berkeley and close friend of J. Robert Oppenheimer. In this interview, Chevalier discusses aspects of Oppenheimer’s personal life, including his romantic relationships and family, hobbies including Sanskrit, and religious views. He recalls how Oppenheimer became involved in politics on the Berkeley campus. He also discusses who was present for his infamous conversation with Oppenheimer, in which Chevalier told Oppie he knew a way to pass scientific secrets to the Soviets. This conversation played a key role in Oppenheimer’s security trial in 1954.
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 explains why he opposed developing the hydrogen bomb and provides insight into the General Advisory Committee’s decision to pursue it. He also discusses nuclear proliferation, which scientists may have influenced J. Robert Oppenheimer’s thoughts on the hydrogen bomb, and the challenges of developing the H-bomb.
Robert Christy studied under J. Robert Oppenheimer at the University of California, Berkeley while earning his PhD in theoretical physics. He joined the Manhattan Project in February 1942 at the University of Chicago, and later relocated to Los Alamos when Oppenheimer personally recruited him on a visit to Chicago. At Los Alamos, Christy worked on the design of the water-boiler reactor. He was then recruited into the implosion group, where he designed the Christy gadget, the solid-core design of the plutonium bomb. He also witnessed the Trinity test. In this interview, he recalls what Oppenheimer was like as a professor and lecturer, his love for martinis, and his relations with graduate students. Christy discusses Oppenheimer’s role in the field of physics as a stimulator of ideas, and how it changed after his security trial. He also discusses Oppenheimer’s impact in emphasizing the value of theoretical physics in America. Christy remembers sharing a house with Edward Teller in Chicago and working with Klaus Fuchs and Rudolf Peierls.
Dorothy McKibbin was known as the “Gatekeeper to Los Alamos.” Everyone and everything who worked on the Manhattan Project at the site had to pass through her office at 109 East Palace in Santa Fe. Her important position as well as her friendly disposition helped her form lasting relationships with many Manhattan Project workers. In this interview, McKibbin discusses what happened to the scientists after the project, and details some of the stringent security procedures at Los Alamos. She also characterizes Oppenheimer as a charismatic and kind leader beloved by the community, who did not deserve the harsh treatment he was subjected to during his security hearing. She also describes how many of those who worked with Oppenheimer supported him, and some even tried to intervene during his hearing to no avail.
