Roger Fulling served as a division superintendent in DuPont's War Construction Program. In this interview, he discusses the priority that the Manhattan Project received in the industrial sector, especially with materials like aluminum. He talks about coordinating production with the armed forces, including General Douglas MacArthur. He explains how General Leslie R. Groves would intervene if a company was having difficulty acquiring materials or producing products to certain specifications. Fulling also mentions meeting some of the top scientists, including Eugene Wigner, who thought that scientists alone, not DuPont and their engineers, should work on the project, and how DuPont persuaded them otherwise. He remembers his interactions with General Groves after the war, and explains why Groves chose DuPont to work on the Manhattan Project.
Vincent (“Bud”) Whitehead was a counterintelligence officer at Hanford during the Manhattan Project; his wife Clare was a secretary and a member of the Women’s Army Corps. In part two of their interview with S. L. Sanger, the Whiteheads discuss crime at Hanford and the project’s intense secrecy. Clare recalls when she was stricken with polio and how the DuPont doctors were far superior to the Army doctor. The couple also speculates on whether Bud’s subsequent health issues are related to radiation exposure. Finally, Bud recalls chasing and bringing down a Japanese balloon bomb.
Hal Behl and his wife, Reggie, an art teacher, arrived in Oak Ridge in 1945. A member of the Special Engineer Detachment, Behl served as Assistant Supervisor in an Engineering Department laboratory at the K-25 plant. He focused mainly on designing and building laboratory, process, health physics, and quality assurance equipment. In this interview, Behl describes everyday life at Oak Ridge and his experiences renting various rooms around the “Secret City.” He also discusses how his Manhattan Project work helped lead to his postwar career in aerospace and weapon system technology.
Elsie McMillan was the wife of Nobel Prize winner Edwin McMillan and sister-in-law of another Nobel Prize winner, Ernest Lawrence. She came to Los Alamos in 1943 with Edwin and their baby Ann. In this speech, she takes the audience on an imaginary tour of Los Alamos, complete with detailed descriptions of various buildings and their home, today known as the Hans Bethe House. Her speech characterizes what civilian life was like at Los Alamos for the wives of many scientists, including the challenges of shopping with ration cards and dealing with the tight security. She fondly recalls Pascualita, a Pueblo woman who helped her around her home and invited the McMillans to her home in the Pueblo. Elsie dramatically recalls the tension of the Trinity Test, waiting to find out whether the test was a success and that all the scientists were uninjured.
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.
Harold Cherniss was an American classicist. He initially met J. Robert Oppenheimer at Berkeley in 1929, and they reconnected after the war in Berkeley and later at the Institute for Advanced Study. In this interview, Cherniss reflects on his friendship with Oppenheimer and his experience with others who knew him. Among other subjects, he discusses Oppenheimer’s personality, intellectualism, friendships, and political leanings. He recalls Oppenheimer’s interest in literature, especially French poetry. Cherniss explains how and why Oppenheimer became interested in studying Sanskrit – because Oppie loved a challenge.
Dr. Baldwin Sawyer was a metallurgist who worked at the Chicago Met Lab during the Manhattan Project. He got involved with the Manhattan Project through his father Charles Baldwin Sawyer, who conducted important research into beryllium. In this interview, Sawyer recounts his experiences during the war. He describes the challenges of developing the uranium canning process for the reactors at Hanford, the project’s sense of urgency, and the boardinghouse he lived in on the South Side of Chicago. He also explains his postwar work with quartz and the pioneering research he conducted into silicon at Bell Laboratories.
Geoffrey Chew was an undergraduate studying physics at George Washington University when he assisted Washington Post journalist (and future children’s novelist) Jean Craighead in writing an article on atomic weapons. His professor, George Gamow, recommended that Chew join Edward Teller’s team at Los Alamos. At Los Alamos, Chew witnessed the Trinity Test from a nearby mountain and worked on Teller’s ideas for developing the hydrogen bomb. In graduate school, Chew was supervised by Enrico Fermi. In this interview, Chew recounts his unique entrance to the Manhattan Project and his relationship with Edward Teller. He also recalls an incident when Fermi had trouble playing a game at a party, his conversation with an intelligence man on the Craighead article, and serving as John von Neumann’s “human computer.” Finally, Chew discusses his current research on the Big Bang.
In 1943, J. Robert Oppenheimer recruited American physicist Robert Bacher to join the Manhattan Project as head of the experimental physics division at Los Alamos. Bacher went on to direct the bomb physics division at Los Alamos from 1944 to 1945, helping oversee the design of the implosion bomb, known as “Fat Man,” that was dropped on Nagasaki. In this interview, Bacher recalls how the Los Alamos laboratory was forced to shift gears from the gun-type design for the plutonium bomb to the implosion-type method. He also describes his post-war service as a member of the Atomic Energy Commission.
Robert R. Wilson was an American physicist. He studied at the University of California, Berkeley, where he first met Oppenheimer. Oppenheimer recruited Wilson and his entire group at Princeton to work on the Manhattan Project at Los Alamos on the cyclotron. After arriving at Los Alamos in 1944, Wilson became head of the Research Division. In this interview, Wilson reflects on his time working with Oppie, including his personality, political views, and Oppenheimer’s unwillingness to engage him on the moral implications of building the bomb. He discusses Oppenheimer’s controversial security hearing and recalls how it affected Oppenheimer. Wilson recalls how he and other scientists fought against Atomic Energy Commission Chairman Lewis Strauss’s appointment as Secretary of Commerce in retaliation for Strauss’s role in the hearing.
