Otto Robert Frisch
Otto Robert Frisch (1st October 1904 – 22nd September 1979) was a Jewish physicist. With his Jewish comrade Rudolf Peierls he designed the first theoretical mechanism for the detonation of an atomic bomb in 1940. Frisch was Jewish, born in Vienna, Austria, in 1904, the son of Justinian Frisch, a painter, and Auguste Meitner Frisch, a concert pianist. Frisch moved to London in 1933. He and the physicist Rudolf Peierls produced the Frisch–Peierls memorandum at Birmingham University, which was the first document to set out a process by which an atomic explosion could be generated. This memorandum was the basis of British work on building an atomic device (the Tube Alloys project) and also that of the Manhattan Project on which Frisch worked as part of the British delegation. Frisch and Rudolf Peierls worked together in the Physics Department at Birmingham University 1939–40. He went to America in 1943 having been hurriedly made a British citizen.
