Oral Histories

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.

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.

Harris Mayer is an American physicist. A student of both Edward Teller and Maria Goeppert-Mayer, he worked at Columbia University during the Manhattan Project. He moved to Los Alamos in 1947 to work at the Los Alamos laboratory, and his early work contributed to the development of the hydrogen bomb. In this interview, Mayer discusses his close friendships with other scientists and his work on the Operation Greenhouse nuclear tests. He shares stories about Teller, Frederick Reines, and Richard Feynman, and recalls attempting to mediate the conflict between Teller and Hans Bethe.

Dr. James Hershberg is a leading scholar on Cold War history. In this interview, Hershberg explains in great detail the complex history of the Manhattan Project. He explores the scientific and political climate leading up to the Project, the symbolism and implications of the atomic bomb, and the feelings of various Manhattan Project scientists. He also explains the debate over developing the hydrogen bomb, different historical perspectives for explaining the Manhattan Project, James B. Conant’s recollections of witnessing the Trinity Test, and U.S./Soviet Union relations throughout the Cold War. Hershberg ends the interview by discussing how various nations have become nuclear powers, and how the Cold War and nuclear history are relevant today.

Dr. Jon Hunner is a Professor of History at New Mexico State University, the author of “Inventing Los Alamos” and “J. Robert Oppenheimer, the Cold War and the Atomic West,” and a former director of the New Mexico History Museum. In this interview, Hunner provides an overview of life at Los Alamos during the Manhattan Project, including its takeover of the Los Alamos Ranch School and its relationship with Hispanos and Pueblos in the area. He talks about how Manhattan Project scientists and their family members would arrive in Santa Fe, and the sites in Santa Fe that are linked to the project. Hunner also discusses J. Robert Oppenheimer and his family, and Oppenheimer’s security hearing that revoked his security clearance. He describes the devastating effects of the atomic bombs on the Japanese who lived in Hiroshima and Nagasaki, and discusses his thoughts on the influence of the atomic bombs on Japan’s decision to surrender.

Margaret Norman is the eldest daughter of Nobel Prize-winning physicist Ernest O. Lawrence. In this interview, Norman describes her father’s childhood, including the importance of her father’s Norwegian heritage and values, and how her parents met. She recalls what it was like to grow up as the eldest daughter of six children, and how Ernest passed his values on to them. She describes visiting the laboratory at Berkeley where her father worked, and finding out about the atomic bombs and Ernest’s involvement. Margaret also recalls her father’s friendship with J. Robert Oppenheimer, Edward Teller, and other scientists, and explains that he could never really relax because he was always thinking about science.

Martin J. Sherwin is a historian and professor at George Mason University, specializing in the development of atomic weapons and nuclear policy. With Kai Bird, Sherwin co-authored “American Prometheus,” the Pulitzer Prize-winning biography of J. Robert Oppenheimer. In this interview, Sherwin discusses Oppenheimer’s childhood, family life, and personality, including his love of the mountains of New Mexico, and his leadership at Los Alamos during the Manhattan Project. He also discusses why Oppenheimer did not support building the hydrogen bomb. Sherwin reflects on the decision to drop the atomic bombs on Hiroshima and Nagasaki, arguing that the atomic bombs were not necessary to end the war with Japan.

James L. Smith is a physicist at Los Alamos National Laboratory (LANL). In this interview, Smith recalls his more than forty-year career at LANL. He describes some of the history of the Manhattan Project and LANL’s innovative work during the war through today, including work on the human genome, computing, and radiation detection. He emphasizes the importance of having multidisciplinary national laboratories to produce pioneering innovations and scientific discoveries. Smith also recalls his friendship with Edward Teller, who he was assigned to teach about superconductivity, and other Manhattan Project scientists including Nicholas Metropolis. He discusses Teller’s relationship with Oppenheimer and other scientists.

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.

John Manley was a nuclear physicist who worked for the Manhattan Project from its early days. In this interview with Martin Sherwin, Manley recalls being impressed by George Kennan and Omar Bradley’s testimony before the Atomic Energy Commission. He also discusses the contributions to the project and personalities of General Kenneth Nichols, General Leslie Groves, and Peer de Silva. He also explains the founding of Los Alamos and and reflects on Oppenheimer’s transition into the “great administrator.”
