Oral Histories

Raymond Sheline was a chemist at Columbia University and a member of the Special Engineer Detachment at Oak Ridge and Los Alamos. After graduating from college in 1942, Sheline received a telegram from Harold Urey inviting him to join the Manhattan Project at Columbia. His group at the university focused on resolving problems caused by corrosion during the gaseous diffusion process. After being drafted into the Army, Sheline was sent to Oak Ridge and Los Alamos as a member of the Special Engineer Detachment. At Los Alamos, he contributed to work on the trigger for the plutonium bomb. In this interview, Sheline discusses his early life and educational background. He describes memories from growing up in Ohio and from his time studying Chemistry at Bethany College. He also explains his time in the U.S. Army and how he came to work with the SED. Sheline then recalls how he met his wife Yvonne. Lastly, Sheline discusses his life after earning his Ph.D. at the University of California, Berkeley, including briefly working in Germany, working at the University of Chicago, how his career began at Florida State University, and his time researching in Copenhagen.

Richard Rhodes is the Pulitzer Prize-winning author of “The Making of the Atomic Bomb,” “The Twilight of the Bombs,” “Dark Sun,” and “Energy: A Human History,” as well as more than twenty other books. In this interview, Rhodes expounds on the character of J. Robert Oppenheimer, the inevitability of discovering nuclear fission, the development of the hydrogen bomb, nuclear proliferation and the Cold War arms race, and the relationship between the Soviet Union and United States. He also discusses his play “Reykjavik,” based on the 1986 meeting between Mikhail Gorbachev and Ronald Reagan.

David Holloway, author of “Stalin and the Bomb: the Soviet Union and Atomic Energy 1939-1956,” is a professor of history at Stanford University. An expert on the international history of nuclear weapons, Dr. Holloway traces the development of the Soviet Union’s nuclear capabilities and policy throughout the Cold War. He discusses the beginnings of the Soviet atomic bomb project in World War II, the rise of the Cold War, and the development of the USSR’s hydrogen bomb. He also offers remarks on the current state of nuclear weapons internationally.

Robert S. Norris is a senior fellow at the Federation of American Scientists and author of the definitive biography of General Leslie R. Groves, “Racing for the Bomb: General Leslie R. Groves, the Manhattan Project’s Indispensable Man.” In this interview, Norris provides an overview of how the Manhattan Project began, how the project sites were selected, and the role of British scientists in the project. He discusses the fear that many Manhattan Project scientists felt that Germany would develop an atomic bomb first. He explains Groves’ background, why he was the perfect leader for the project, and how he involved industry, especially DuPont, to help with the project. Norris contends that the Manhattan Project was a unique program in American history and would be difficult to replicate today.

Philippe Halban is a European biologist. His father, Hans Halban, was an eminent physicist who conducted nuclear research with Frédéric Joliot-Curie in France in the years leading to World War II and then in England and Canada as part of the Anglo-French nuclear effort. In this interview, Philippe provides an account of his father’s life, including Halban’s family, education, and love of science. He discusses his father’s relationships with fellow scientists, including Francis Perrin, Lew Kowarski, and Joliot-Curie. He also describes how his father and Kowarski fled France for England in June 1940 with France’s supply of heavy water to keep it out of the hands of the Nazis.

Robert I. (“Bob”) Howes Jr. is an American physicist. He was a young child when his father, Robert Ingersoll Howes, was recruited to work as a scientist on the Manhattan Project in Los Alamos, New Mexico. In this interview, Howes shares snapshots of daily life in the Los Alamos community from the perspective of a child. He also describes some of the interaction between the Manhattan Project and local Pueblos and recalls the misadventures of the family dog.

Julie Melton is an author and expert on civil society, development, and democratization. She is the daughter of Manhattan Project historian David Hawkins and Frances Hawkins, the founder of the nursery school at Los Alamos. During the Manhattan Project, her family lived in the same four-family house as Victor and Ellen Weisskopf, who became some of their closest friends. In this interview, she shares her childhood memories of Los Alamos and anecdotes about prominent Manhattan Project scientists. She also describes her parents’ involvement in the Communist Party at Berkeley, where her father met J. Robert Oppenheimer. She concludes with a brief reflection on the frustrations of being a woman at Los Alamos.

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.

Esther Floth worked as a secretary for General Leslie Groves during the Manhattan Project in Washington, DC. Her job afforded her the opportunity to meet leading Manhattan Project officials and scientists, including J. Robert Oppenheimer, Niels Bohr, Ernest Lawrence, and others. She went on to work for the Atomic Energy Commission after the war. In this interview, Esther recalls the secrecy of the project, including getting her top-secret clearance, and what everyday life during the war was like. She recounts General Groves’s leadership qualities and how he interacted with her and other Manhattan Project staff. Floth also describes her response to the dropping of the atomic bombs on Hiroshima and Nagasaki and Oppenheimer’s security trial.

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 directed 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 the initial conference of Los Alamos laboratory leadership in 1943 and describes Oppenheimer’s relationships with Enrico Fermi and General Leslie Groves. He recounts how Oppenheimer improved as a lecturer, and remembers the excitement caused in the physics community by the development of quantum mechanics and the discovery of the neutron.
