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.
Roger Fulling was the Division Superintendent of Construction at DuPont during the Manhattan Project, which meant that he coordinated and expedited the construction projects at Hanford and Oak Ridge. He was also the main liaison with General Leslie R. Groves on the Hanford construction project. In this interview, Fulling discusses DuPont’s procurement issues and the support of American industry for the Manhattan Project. He also recalls visiting Hanford and the early days of working with General Groves. He explains the fate of Hanford's orchards and farms after the Manhattan Project requisitioned the land, and his sadness at witnessing the orchards fall into ruin.
In this interview, Roger Fulling discusses the various positions he held at DuPont during and after the war. He recalls a special request from the Australian government for smokeless powder that DuPont had to fulfill, as well as outlining the structure and history of the DuPont Company. He explains the other wartime work of the DuPont Company and how DuPont had to balance its Manhattan Project work with its other military contracts.
Verna Hobson worked as a secretary for J. Robert Oppenheimer at the Institute for Advanced Study at Princeton University. Her tenure as his secretary coincided with Oppenheimer's investigation by the Atomic Energy Commission. In this interview, she shares her interactions with the Oppenheimer family. As Robert Oppenheimer’s personal secretary, she maintained close relationships with him, his wife, and his children. She provides insight into Kitty Oppenheimer’s personality, and how Kitty and Robert interacted with each other and their children, Peter and Toni. She recalls what Peter and Toni were like as children, and how she cared for Peter when Kitty and Robert were abroad. Hobson gives particular insight to her relationship with Kitty Oppenheimer, whose struggles with alcoholism and depression were exacerbated by Robert’s death. She recalls some of the stories that Kitty shared with her during this period, as well as her own personal recollections about Robert’s bout with cancer.
Carl D. Anderson was a physicist who won a Nobel Prize for the discovery of the positron. He studied and taught at the California Institute of Technology (Caltech), where he took a class with a young professor named J. Robert Oppenheimer. In this interview, he discusses his impressions of Oppenheimer, including Oppenheimer’s early struggles as a teacher. Anderson describes the research that was going on at Caltech during the 1930s, including the groundwork that went into his Nobel-winning discovery. He also details why he turned down a role on the Manhattan Project, and the work he did on rockets during World War II instead.
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.
