Fuchs, Klaus Emil Julius (29 December 1911–28 January 1988), physicist and spy, was born in Russelheim, near Frankfurt, Germany, the son of Emil Fuchs, a Lutheran minister, and Else Wagner. Klaus Fuchs studied mathematics and physics at Leipzig University (1928–1931) and continued his undergraduate studies in physics at Kiel University (1931–1933). As a student at Kiel University, he joined, first, the Social Democratic party and, in 1932, the German Communist party. After the Reichstag fire in February 1933, and the attendant Nazi reprisals against the political Left, Fuchs went into hiding in Berlin for a few months, then migrated to Britain in September 1933. He continued his studies in physics at Bristol University, where he secured a position as a research assistant to Neville Mott. In his research Fuchs applied quantum physics to questions of the electrical resistance of metallic films, working with Bernard Lovell, who was later knighted for his achievements in physics. In 1937 Fuchs was granted a Ph.D. in physics at Bristol. A paper that resulted from his doctoral research, “A Quantum Mechanical Calculation of the Elastic Constants of Monovalent Metals,” appeared in the ...
