Oral Histories

Marshall Rosenbluth was an American physicist who worked in the theoretical division at Los Alamos from 1950 to 1956. In this interview, Rosenbluth addresses the theoretical issues involved in designing both the atomic and hydrogen bombs. He discusses how the pressure to create a nuclear bomb before the Soviet Union affected work in the laboratory, especially in performing and checking calculations. Rosenbluth also recounts his experiences during the nuclear weapons tests at Los Alamos and Bikini Atoll. He recalls the roles of top scientists, like Edward Teller, Hans Bethe, Enrico Fermi, and Carson Mark, in the building of the hydrogen bomb. He also explains how funding and other external factors affected the hydrogen bomb’s design.

David Kaiser is the Germeshausen Professor of the History of Science and a Senior Lecturer in the Department of Physics at the Massachusetts Institute of Technology. He is author of the award winning book “Drawing Theories Apart: The Dispersion of Feynman Diagrams in Postwar Physics,” and more recently published “How Hippies Saved Physics: Science, Counterculture, and the Quantum Revival.” His discussion with Atomic Heritage Foundation President, Cindy Kelly, focuses on the birth of nuclear physics and the nuclear bomb, but ranges across scientific developments in the early-to-mid 20th Century. Kelly and Kaiser also deliberate on the facets of innovation, and connect the scientific legacy of the Manhattan Project to current scientific research.
