Joseph Rotblat was a British-naturalized Polish physicist, 1995 Nobel Peace Prize winner, and founder of the Pugwash Conferences. Rotblat and his friend James Chadwick, discoverer of the neutron, conducted early research on the atomic bomb in England, and both joined the British Mission at Los Alamos working on the Manhattan Project. Rotblat left the Manhattan Project on grounds of conscience in late 1944 when it became clear Germany was not close to developing an atomic bomb—the only scientist to leave the project for moral reasons. In this interview, he discusses his personal and professional relationships with J. Robert Oppenheimer, Niels Bohr, and the Chadwick family. He also provides insight into the intense security measures in place at Los Alamos, as well as the nature of British involvement at the site. Perhaps most intriguing is Roblat’s discussion of his decision to leave Los Alamos, spurred on by his growing concern that the nuclear weapons being created were also meant for the Soviet Union, and his anxiety over a postwar arms race. In a lighter vein, Rotblat also recalls his work as a technical advisor on the 1980 miniseries “Oppenheimer.”

The Atomic Heritage Foundation (AHF), founded by Cynthia Kelly in 2002, is a nonprofit organization in Washington, DC, dedicated to the preservation and interpretation of the Manhattan Project and the Atomic Age and its legacy.
 
The Foundation's goal is to provide the public not only a better understanding of the past but also a basis for addressing scientific, technical, political, social and ethical issues of the 21st century. AHF works with Congress, the Department of Energy, National Park Service, state and local governments, nonprofit organizations and the former Manhattan Project communities to preserve and interpret historic sites and develop useful and accessible educational materials for veterans, teachers, and the general public.
