Oral Histories

Floy Agnes Lee was one of the few Pueblo Indians to work as a technician at the Los Alamos laboratory during the Manhattan Project. As a hematologist, she collected blood from Manhattan Project scientists, including from Louis Slotin and Alvin Graves after the criticality accident that exposed Slotin to a fatal amount of radiation. After working at Los Alamos, she transferred to the Chicago Met Lab, and later Argonne National Laboratory and the Jet Propulsion Laboratory. While working and caring for her daughter Patricia as a single mother, she earned her Ph.D. at the University of Chicago. Over the course of her long career, she conducted research on the impact of radiation on chromosomes. In this interview, Lee recalls her interactions with Slotin and Graves after the accident and playing tennis with Enrico Fermi. Her parents were Pueblo and White, and she discusses how that has shaped her life. She also describes visiting her family at the Santa Clara Pueblo and her ancestors’ involvement in the politics of the Pueblo.

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.

Louis Hempelmann was the director of the Health Group at Los Alamos. He and his wife Elinor became close friends with J. Robert and Kitty Oppenheimer. In this interview, Hempelmann discusses the lives of Peter and Toni Oppenheimer, Robert and Kitty’s children. He recalls visiting the Oppenheimer home on St. John’s in the Caribbean, and explains that all the Oppenheimer homes were decorated in a rather focused, austere manner. He remembers Oppenheimer’s concern that he was being followed or secretly recorded after the war, as well as Oppie’s incredible ability to speed read. Hempelmann also recalls going horseback riding with Oppie and having dinner at Edith Warner’s home by Otowi Bridge.
