Hans-Peter Dürr (7 October 1929 – 18 May 2014) was a German physicist. In addition to nuclear and quantum physics, elementary particles and gravitation, epistemology, and philosophy, he has advocated responsible scientific and energy policies.
Born in Stuttgart, between 1978 and 1992 he was executive Director of the Max Planck Institute for Physics and Astrophysics in Munich for several times. He was Vice executive director at the Max Planck Institute for Physics (Werner-Heisenberg-Institute) 1972-1977, 1981–1986 and 1993-1995. Until 1997 he was professor of physics at the Ludwig Maximilian University, both in Munich, Germany.
Dürr completed his Ph.D. in 1956 after studying physics in Stuttgart (Dipl.-Phys. 1953) and at University of California in Berkeley, supervised by Edward Teller. In 1962 he was a guest-professor in Berkeley, California and Madras, India.
As "the" follower of Prof. Werner Heisenberg, he specializes in nuclear physics, quantum physics, elementary particles and gravitation, epistemology and philosophy. He was Heisenberg's closest ally in their attempts to develop a unified field theory of elementar particles. He also champions various social justice causes, and helped fund the "David against Goliath" organization protesting against a nuclear fuel reprocessing plant in Bavaria.
