$Gerhard Borrmann (Born: April 30, 1908 deceased: April 12, 2006) was a German physicist. He was born in Diedenhofen, then part of Germany, and received his early education there. He continued his secondary school at Gießen, where he apprenticed at a steel mill. After studying at the Technische Universität München and Technische Hochschule Danzig, he wrote his Ph.D. thesis on the Kossel effect while working at the laboratory of Walther Kossel in Danzig. Following his doctorate, he continued to work at the laboratory as an assistant to Kossel, where he studied X-ray transmission through thin crystal foils. Due to his refusal to join the Nazi Party, he was forced to leave the laboratory in 1938, upon which he went to work with Max von Laue at the Kaiser-Wilhelm-Institut für Physikalische Chemie und Elektrochemie (KWI). There he discovered a phenomenon regarding the anomalous low absorption of X-rays that became known as the ‘Borrmann effect’ (or ‘Borrmann-Campbell effect’, for Herbert N. Campbell.) Following the war, in 1951 Bormann was offered the Kristalloptik der Röntgenstrahlen department of the KWI. He became a Scientific Fellow in 1956. He was appointed Professor at the Technische Universität Berlin, retiring in 1970. In 1996, the Deutsche Gesellschaft für Kristallographie honored Gerhard Borrmann pioneering work in X-ray diffraction with the first Carl-Hermann Medal.$ Gerhard Borrmann	$The Borrmann effect (or Borrmann–Campbell effect after Gerhard Borrmann and Herbert N. Campbell) is the anomalous increase in the intensity of X-rays transmitted through a crystal when it is being set up for Bragg reflection. The Borrmann effect—a dramatic increase in transparency to X-ray beams—is observed when X-rays satisfying Bragg's law diffract through a perfect crystal. The minimization of absorption seen in the Borrmann effect has been explained by noting that the electric field of the X-ray beam approaches zero amplitude at the crystal planes, thus avoiding the atoms.$ Borrmann Effect	Giuseppe Borsalino	Borsalino	Borstal, Rochester	Borstal
