Emil Julius Klaus Fuchs was a German theoretical physicist and atomic spy who, in 1950, was convicted of supplying information from the American, British, and Canadian Manhattan Project to the Soviet Union during and shortly after the Second World War. After nine years' imprisonment in Great Britain, he re-migrated to the German Democratic Republic where he resumed his career as a physicist and scientific leader. While at the Los Alamos National Laboratory, Fuchs was responsible for many significant theoretical calculations relating to the first nuclear weapons and, later, early models of the hydrogen bomb.
