Joseph Rotblat’s Interview
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.”
