Erich Habann

from Wikipedia, the free encyclopedia

Erich Habann (born August 6, 1892 in Soldau, East Prussia , † March 24, 1968 ) was a German physicist and communications engineer .

Life

He began his scientific career in the First World War as an assistant to Prof. Heinrich Fassbender . In 1918 they demonstrated a high-frequency carrier-frequency telephone traffic from three simultaneous telephone connections between Berlin and Potsdam. Half a year later, a public postal carrier frequency telegraphy traffic between Berlin and Weimar (seat of the National Assembly) could be set up. Fassbenders and Habanns bear the names of almost 100 patents and patent applications from the early days of carrier frequency technology.

After his doctorate at the physics institute of the University of Jena under the direction of Max Wien with the thesis A new generator tube (1924) on a two-slot magnetron with an external oscillating circuit, he received his habilitation in 1928 at the TH Braunschweig and later an associate Professor for circuit theory in telecommunications. Hans Erich Hollmann worked with this magnetron.

At the outbreak of World War II he was among the scientists who Erich Schuhmann to WAF (Research Department of the Army Ordnance Department , emerged from the Center for Army Physics and army chemistry , from 1933 under the name Wa testing 11 , 1938 renamed WAF ) was convened and there on news technical Area researched. In March 1942 he helped Erich Bagge with the patent application for his isotope lock. He also applied for a patent with which "the transistor in its original form was first specified by Erich Habann".

From 1945 he worked at the Soviet Institute in Berlin for the reconstruction of German missile technology. In 1947 he was hired as a specialist in the Soviet Union, where he worked in his field and was released to the GDR in 1951.
