Harry Lehmann

Harry Lehmann ( born March 21, 1924 in Güstrow, † November 22, 1998 in Hamburg ) was a German physicist.

Life and work

Lehmann made ​​after high school in 1942 in Rostock his military service in North Africa, where he was taken in captivity and was three years in a U.S. prison camp. He studied physics from 1946 in Rostock and later at the Humboldt University of Berlin (Diploma in Experimental Physics ). He received his doctorate in 1950 at Friedrich Hund in Jena ( on a theme of classical electrodynamics ), whose assistant he was. In 1952 he came to what was then the Max Planck Institute for Physics in Göttingen (on invitation by Werner Heisenberg ), also worked for a year in Copenhagen (as a member of the CERN Study Group ), to finally take in 1956 a professorship in Hamburg (successor of Wilhelm Lenz ). In Hamburg, he was involved in a central location in the building of the German Electron Synchrotron, especially also in the establishment of the theoretical institution.

Harry Lehmann was a pioneer of quantum field theory ( QFT ); in the 1950s he published, mostly in collaboration with Kurt Symanzik and Wolfhart Zimmermann fundamental work on QFT, most famously the LSZ reduction formula for calculating the S- matrix in 1955. This work has evolved over the original objective addition, throughout the theoretical physics proved fruitful, for example in the theory of so-called " linear Response " at various derivations of the " fluctuation-dissipation theorem ".

Harry Lehmann received the 1967 Max Planck Medal of the German Physical Society and the 1997 Dannie Heineman Prize for Mathematical Physics of the American Physical Society.

His doctoral include Klaus Pohlmeyer and Bert Schroer.
