He was a participant in a group known as the “first Uranverein,” which was spawned by a meeting conducted by the Reichserziehungsministerium, in April 1939, to discuss the potential of a sustained nuclear reaction. He worked under Werner Heisenberg at the University of Leipzig, and he conducted experiments on spherical layers of uranium oxide surrounded by heavy water. He was a contributor to the German nuclear energy project (Uranverein). In 1945, he was sent to Russia to work on the Soviet atomic bomb project. He returned to Germany in 1957, and he become professor of electrical engineering and director of the Institut für Angewandte Physik at the Hochschule für Elektrotechnik.
