Oral Histories

Masao Tomonaga is the honorary director of the Japanese Red Cross Nagasaki Atomic Bomb Hospital and a hibakusha, an atomic bomb survivor. He studied internal medicine and hematology at the Nagasaki University Medical School. Currently, he runs a retirement home for older hibakusha. In this interview, Dr. Tomonaga discusses his experience surviving the bombing of Nagasaki. He outlines the immediate physical impacts the bomb had on people’s bodies, the long-term physical impacts, such as cancer, and the psychological harm. He also discusses the simulation Japan’s Ministry of Foreign Affairs conducted to see what a one-megaton nuclear detonation would look like in a modern city today.

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.

Raymond Sheline was a chemist who worked on the Manhattan Project at Columbia University, Oak Ridge, and Los Alamos. Sheline received his Ph.D. from the University of California at Berkeley in 1949 and was a professor at Florida State University for 48 years. Among other accomplishments, he helped establish a nuclear chemistry lab at the Niels Bohr Institute in Copenhagen and published more than 400 scientific papers. In this lecture, Sheline discusses how he initially joined the Manhattan Project, his work on gaseous diffusion at Columbia University under Nobel Prize winner Harold Urey and how he became a member of the Special Engineer Detachment. He also delves into the history of nuclear physics, providing an overview of key discoveries and personalities including J. Robert Oppenheimer, Enrico Fermi, and Edward Teller.

Robert “Bob” Krauss is the Official Historian of the 509th Composite Group. He and his wife, Amelia Krauss, published The 509th Remembered, which profiles the service members of the 509th Composite Group and the events that surrounded the group and its role in dropping the atomic bombs on Hiroshima and Nagasaki. In this interview, Krauss discusses how he became interested in collecting and preserving the history of the 509th and became the official historian for the 509th CG. He also narrates the stories of airmen from the 509th Composite Group and recounts his relationship with some of the airmen, including Donald Albury, Ray Gallagher, Fred Olivi, Paul Tibbets, and others. He reflects on the atomic bombings, the legacy of the Manhattan Project, and visiting some of the Manhattan Project sites today.

Robert S. Norris is a senior fellow at the Federation of American Scientists and is the author of the definitive biography of General Leslie Groves. In this interview, Norris provides an overview of the French atomic program, describing the influence of Marie Curie and Frédéric Joliot-Curie. He goes on to explain how nations, including the United States, the Soviet Union, Great Britain, and France, became nuclear powers in the context of the Cold War. He also discusses current debates over nuclear weapons. Norris provides insight into the creation of the 509th Composite Group, and the U.S. decision to use the atomic bombs in Japan.

Victor Kumin was a young scientist when he was drafted into the U.S. Army in 1944. In September of that year, he was transferred to Los Alamos, where he was a member of the Special Engineer Detachment (SED). In this interview, courtesy of the Story Preservation Initiative, Kumin discusses his time as a Chemistry student at Harvard and joining the Manhattan Project at Los Alamos. He recalls the secrecy of the project and how he felt about the decision to use the atomic bombs.

Clifton Truman Daniel is the grandson of President Harry Truman. In this interview, Daniel discusses what it is like to be the grandson of the president. He recalls his relationship with his grandparents and his mother, Margaret Truman Daniel, and how he learned that “Grandpa” had been president. In addition to discussing the work that he does on behalf of the Truman Presidential Library, Daniel also speaks about the more recent trips he has made to Japan and meeting with survivors of the atomic bombings of Hiroshima and Nagasaki. He describes his friendships with survivor Setsuko Thurlow and with the family of Sadako Sasaki.

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.

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.

Larry DeCuir served in the 509th Composite Group during World War II. In this interview, he discusses his experience being stationed on Tinian Island during the war and working on the X unit of the Fat Man bomb, which was designed to trigger the bomb. He also reflects on the level of secrecy involved in the Manhattan Project. DeCuir describes the housing on Tinian, and recalls witnessing the B-29 planes take off from Tinian airfield for missions over Japan.
