He was the father of the neurobiologist Martin Heisenberg and the son of August Heisenberg. Werner Karl Heisenberg (German: [ËhaÉªzÉnbÉÉÌ¯k]; 5 December 1901 â 1 February 1976) was a German theoretical physicist and one of the key pioneers of quantum mechanics. He published his work in 1925 in a breakthrough paper.
During World War II he led Germany's failed efforts to develop an atomic bomb, though his group never came close to achieving this goal and Heisenberg himself doubted it was possible. After the war he was briefly imprisoned in England, before resuming his academic work in Germany.
