Fritz Fischer (physicist)

Fritz Fischer ( born February 9, 1898 in Signau BE, † December 28, 1947 in Zurich ) was a Swiss electrical engineer. He was married to Maud Schaetti since 30 July 1936.

He studied from 1917 to 1924 electrical engineering at the ETH Zurich and completed his studies with a dissertation Theoretical studies of high-value resistors for measurement purposes in the high voltage alternating current technology from. The phone works Albisrieden he improved in 1924/25 the quality of voice transmission, after which he was appointed to the Central Laboratory of the parent company Siemens & Halske in Berlin. There he created, among other first remote-controlled ships and aircraft and conducted research on the physical basis of color film. From 1928 he was a member of the leadership of the Central Laboratory. During this time he was also a lecturer at the Technical University Berlin.

In 1932 he took up an appointment at the ETH Zurich, where he established the Institute for Technical Physics and the Eidophor method developed to transfer the television pictures in movie screen size allowed. Yet his chief assistant Edgar Gretener supported him, who later in his own company, Edgar AG Gretener the Eidophorsystem further developed. After Greteners death it was the Gretag, which successfully commercialized the invention fisherman.

One of the first scientific staff and PhD students of Fischer included from 1935 Gustav Guanella, Max Lattmann and Werner Lindecker, 1937 Erna Hamburger, which was established in 1957 as the first woman full professor at a Swiss university ( EPUL ), and from 1939 Hugo Thiemann, which in has played a significant role in the development of Eidophor and the transfer of the project in the company Gretener.

Fischer was also Head of the Department for Industrial Research at the ETH ( Afif ). As part of a collaboration with the firm of Brown, Boveri & Cie, Baden ( BBC ) Fritz Lüdi worked as Envoy of the BBC from 1936 to 1939 at the Afif led by fishermen on the high-frequency engineering projects. Lüdi invented 1938 Vielschlitzmagnetron called Turbator, which came as a transmitter tube of BBC radio relays used.

Fischer founded together with his first doctoral Max Lattmann the company Contraves AG in Zurich, initially starting in 1936 a study society in the field of air defense equipment, and later a major Swiss high -tech industrial company with over 2000 employees, the military business is now managed by Rheinmetall Air Defence AG.
