Gerhard Borrmann
Encyclopedia
Gerhard Borrmann was a German physicist.
He was born in Diedenhofen
, then part of Germany, and received his early education there. He continued his secondary school at Gießen
, where he apprenticed at a steel mill. After studying at the Technische Universität München and Technische Hochschule Danzig, he wrote his Ph.D. thesis on the Kossel effect while working at the laboratory of Walther Kossel
in Danzig. Following his doctorate, he continued to work at the laboratory as an assistant to Kossel, where he studied X-ray transmission through thin crystal foils. He was forced to leave laboratory in 1938, upon which he went to work at the Kaiser-Wilhelm-Institut für Physikalische Chemie und Elektrochemie (KWI). There he discovered a phenomenon regarding the anomalous low absorption of X-rays that became known as the "Borrmann effect
" (or "Borrmann-Campbell effect", for Herbert N. Campbell.)
Following the war, in 1951 Bormann was offered the Kristalloptik der Röntgenstrahlen department of the KWI. He became a Scientific Fellow in 1956. He was appointed Professor at the Technische Universität Berlin, retiring in 1970. In 1996, the Deutsche Gesellschaft für Kristallographie honored Gerhard Borrmann pioneering work in X-ray diffraction with the first Carl-Hermann Medal.
