Gerhard Borrmann

from Wikipedia, the free encyclopedia

Gerhard Borrmann (born April 30, 1908 in Diedenhofen , Reichsland Alsace-Lorraine , German Empire ; † April 12, 2006 in Braunfels ) was a German physicist who, in addition to the founders Max von Laue and Paul Peter Ewald, made significant contributions to the dynamic theory of X-ray interference has done.

Life

Borrmann studied at the Technical University of Munich and at the Technical University of Danzig , where he obtained the degree of graduate engineer in 1930. In 1936 he did his doctorate in Danzig under Walther Kossel on the Kossel effect ( on the interference from grid sources when excited by X-rays ). Further collaboration with Kossel ended in 1938 because he had to leave the university because of his refusal to join the NSDAP . He became a research assistant with Max von Laue at the Kaiser Wilhelm Institute for Physical Chemistry and Electrochemistry in Berlin , which later became the Fritz Haber Institute. He spent the late war and the post-war period in southwest Germany. In 1952 he resumed his collaboration with Max von Laue, in 1953 he was head of the “X-ray crystal optics” department at the Fritz Haber Institute until his retirement in 1970.

In 1956 the Max Planck Society appointed him a scientific member. In 1970 he became a corresponding member of the mathematical and natural science class of the Bavarian Academy of Sciences .

In 1996 he was awarded the Carl Hermann Medal of the German Society for Crystallography for his scientific life's work . His name lives on in the effect of the anomalous absorption of X-rays ("Borrmann effect"), which he describes and explains.
