Oral Histories

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.

Frank Settle is an analytical chemist and professor emeritus at Washington and Lee University. He is the author of “General George C. Marshall and the Atomic Bomb.” In this interview, Settle discusses General Marshall’s life before, during, and after World War II. Settle also highlights Marshall’s leadership, his involvement with the Manhattan Project, and his lack of confidence in the atomic bomb. As a chemist, Settle also talks about the importance of chemistry in the Manhattan Project and his latest work on an atomic road map, part of the Alsos Digital Library for Nuclear Issues.

Al Zelver served as a Japanese language officer in the U.S. Army during World War II. He spent a year in Japan after the bombings of Hiroshima and Nagasaki. In this interview, Zelver talks about becoming a Japanese language officer, his time in the China-Burma-India Theater during the war, and seeing the ruins of Hiroshima shortly after the Japanese surrender.

He recalls his time in Japan both immediately after the surrender and years later when he returned to Hiroshima to speak with the Hiroshima Peace Foundation. He reflects on the atomic bombings and nuclear proliferation today, and describes a conversation with Manhattan Project scientist Felix Bloch.

In the second part of his in-depth interview with journalist Stephane Groueff, General Kenneth Nichols discusses his key role in the Manhattan Project and the chain of command. He explains his relationship with fellow Manhattan Project directors General Leslie R. Groves, Secretary of War Henry Stimson, and scientists Vannevar Bush and James B. Conant. Nichols recalls purchasing 1,200 tons of uranium ore from Belgian Edgar Sengier for the project and the challenges of developing a barrier for the gaseous diffusion plant. He also discusses financial accountability and Congressional oversight of the project.

In this interview, General Leslie Groves discusses his relationship with Secretary of War Henry Stimson, who he had great respect for. Groves recalls several meetings with the Secretary, including one which required Groves’s advice on how to prevent a congressman from visiting Oak Ridge and threatening to unveil the top-secret Manhattan Project site to the Senate. Groves also recalls the shocking day that President Roosevelt died, the delay in notifying key people of Roosevelt’s passing, and how his death affected members of the War Department. He also explains his relations with other top military officials.

In this interview, Robert S. Norris traces the chronology of the Manhattan Project from its inception in 1942 through the early years of the Cold War. Dr. Norris, author of “Racing for the Bomb: General Leslie R. Groves, the Manhattan Project’s Indispensable Man,” talks about the crucial role of General Groves, whose energy and determination impelled the Project forward at an incredibly quick pace. Norris also discusses the controversial decision to drop the bomb on Japan and the Soviet atomic program that developed shortly after the end of World War II.
