Voices of the Manhattan Project

Chicago Pile-1 scientists"Voices of the Manhattan Project" is a joint project by the Atomic Heritage Foundation and the Los Alamos Historical Society to create a public archive of our oral history collections of Manhattan Project veterans and their families. 

Our online collection features over 250 audio/visual interviews with Manhattan Project workers and their families, including J. Robert Oppenheimer, General Leslie R. Groves, Glenn Seaborg, Hans and Rose Bethe, George and Vera Kistiakowsky, and many more. We add new interviews every week, so check back often! 

Recent Oral Histories

Stanislaus Ulam's Interview

Stanislaus Ulam was a Polish mathematician recruited to the Manhattan Project in 1943. Ulam worked on hydrodynamical calculations that were crucial to the design of the implosion-type weapon created at Los Alamos. After the war Ulam collaborated with fellow Manhattan Project scientist Edward Teller to create the design for the hydrogen bomb. In this interview Ulam discusses the challenges of performing the equations needed to design a nuclear weapon without the help of computers. He also explores the ongoing tensions with his former partner, Edward Teller, over the origins of what has come to be called the Ulam-Teller design. Finally, Ulam reflects on the legacies of the both the Manhattan Project and the numerous scientists who made it possible.

Eileen Doxford's Interview

Eileen Doxford was a lab assistant at P6, an early site for the British Tube Alloys Project. After answering a radio announcement from the United Kingdom’s government science agency, the Department of Scientific and Industrial Research, she traveled to the M.S. Factory Valley in Rhydymwyn, Flintshire, Wales to assist engineers attempting to develop a process for the separation of uranium isotopes. She worked at P6 from 1943 until just before it was closed in 1945. She reflects on the secrecy surrounding her work, the separation of P6 operations from the other wartime production activities of the factory, and rationing and life in the United Kingdom during the war.

J. Robert Oppenheimer's Interview

In this rare interview, J. Robert Oppenheimer talks about the organization of the Manhattan Project and some of the scientists that he helped to recruit during the earliest days of the project. Oppenheimer discusses some of the biggest challenges that scientists faced during the project, including developing a sound method for implosion and purifying plutonium. Oppie recalls his daily routine at Los Alamos, including taking his son to nursery school.

Jack Aeby's Interview

Jack Aeby was one of the first civilian employees on the Manhattan Project, and captured the only color photograph of the Trinity test. He worked in many areas, starting with transporting people from Lamy to 109 E. Palace Avenue in Santa Fe and then on up the Hill. He was put in charge of the chemical stockroom. Aeby moved to P-5 (Physics Group 5) with Emilio Segrè and Owen Chamberlain. He reactivated the Los Alamos Ranch School’s Boy Scout Troop 22 on demand of the school superintendent. He discusses working with Emilio Segrè at Los Alamos, and how his famous photo of the Trinity test came about.
