Gerhard Borrmann

Gerhard Borrmann ( born April 30, 1908 in Thionville, rich country Alsace- Lorraine, German Empire, † 12 April, 2006 Braunfels ) was a German physicist, who in addition to the founders, Max von Laue and Paul Peter Ewald substantial contributions to the dynamical theory of X-ray interference has done.

Life

Borrmann studied at the Technical University of Munich and the Technical University of Gdansk, where he earned a degree in 1930 a graduate engineer. In 1936 he received his doctorate in Gdansk with Walther Kossel on the Kossel effect ( via the interference from grid sources when excited by X-rays). Further cooperation with Kossel ended in 1938 because he join because of its refusal of the Nazi party, had to leave the university. He was a research associate at the Max von Laue at the Kaiser Wilhelm Institute for Physical Chemistry and Electrochemistry in Berlin, later Fritz Haber Institute. He spent the late war and the postwar West Germany. In 1952 he started the cooperation with Max von Laue on again, 1953, he was until his retirement in 1970 head of the " crystal optics of X-rays " at the Fritz Haber Institute.

Carl -Hermann Medal of the German Society for Crystallography awarded him in 1996 for his scientific life's work. His name lives on in the described and explained by him effect of anomalous absorption of X- rays ( " Borrmann effect").
