Edgar Gretener
Edgar Gretener (2 March 1902 in Lucerne – 21 October 1958 in Zurich) was a Swiss electrical engineer. Gretener was the twelfth of 14 siblings. He studied electrical engineering at Swiss Federal Institute of Technology (ETH Zurich), where he received his Ph.D. in 1929. He then became head of development at the Albiswerk factory in Zurich. In 1930, he worked as head of the telegraph laboratory of Siemens & Halske in Berlin. There he got in contact with Fritz Fischer (physicist), another Swiss engineer, working as a manager at the central research labs of Siemens. When Fritz Fischer got the call to become professor at the ETH Zurich in 1932, he made Gretener his chief assistant a few years later. Fischer invented the Eidophor video projection system. Gretener was in charge of its implementation. When World War II started, the Swiss authorities asked Gretener to develop an encryption device for teleprinters. For this purpose the Dr. Edgar Gretener AG was set up as a company in 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Siemens & Halske
Siemens & Halske AG (or Siemens-Halske) was a German electrical engineering company that later became part of Siemens. It was founded on 12 October 1847 as ''Telegraphen-Bauanstalt von Siemens & Halske'' by Werner von Siemens and Johann Georg Halske. The company, located in Berlin-Kreuzberg, specialised in manufacturing electrical telegraphs according to Charles Wheatstone's patent of 1837. In 1848, the company constructed one of the first European telegraph lines from Berlin to Frankfurt am Main. Siemens & Halske was not alone in the realm of electrical engineering. In 1887, Emil Rathenau had established ''Allgemeine Elektrizitäts-Gesellschaft'' (AEG), which became a long-time rival. In 1881, Siemens & Halske built the Gross-Lichterfelde Tramway, the world's first electric streetcar line, in the southwestern Lichterfelde suburb of Berlin, followed by the Mödling and Hinterbrühl Tram near Vienna, the first electrical interurban tram in Austria-Hungary. 1882 saw the openi ...

Berlin
Berlin ( , ) is the capital and largest city of Germany by both area and population. Its 3.7 million inhabitants make it the European Union's most populous city, according to population within city limits. One of Germany's sixteen constituent states, Berlin is surrounded by the State of Brandenburg and contiguous with Potsdam, Brandenburg's capital. Berlin's urban area, which has a population of around 4.5 million, is the second most populous urban area in Germany after the Ruhr. The Berlin-Brandenburg capital region has around 6.2 million inhabitants and is Germany's third-largest metropolitan region after the Rhine-Ruhr and Rhine-Main regions. Berlin straddles the banks of the Spree, which flows into the Havel (a tributary of the Elbe) in the western borough of Spandau. Among the city's main topographical features are the many lakes in the western and southeastern boroughs formed by the Spree, Havel and Dahme, the largest of which is Lake Müggelsee. Due to its l ...

Fritz Fischer (physicist)
Fritz Fischer (9 February 1898, Oberdiessbach im Emmenthal BE, Switzerland – 28 December 1947, Zurich, Switzerland) was a technical physicist, engineer and inventor. He was married to Maud Schätti.Borgnis, Fritz''Fischer, Fritz''.In: ''Neue Deutsche Biographie'' 5 (1961), p. 185. Retrieved 2020-04-13. Fritz Fischer studied electrical engineering at the ETH Zurich from 1917 till 1921 and graduated as Dr. sc. tech in 1924. Working at the ''Telephonwerke Albisrieden'' he improved the transmission quality of speech, whereupon he was called to the central laboratories of the mother company Siemens & Halske in Berlin. There he built the first remotely controlled ships and airplanes and investigated the physical properties of colour film. Over 70 patent applications resulted from his work at Siemens. He was lecturer at the Technical University of Berlin. 1932 he received a call to the ETH Zurich, where he became professor and founded the Institute of Technical Physics. He ...

Eidophor
An Eidophor was a video projector used to create theater-sized images from an analog video signal. The name Eidophor is derived from the Greek word-roots ''eido'' and ''phor'' meaning 'image' and 'bearer' (carrier). Its basic technology was the use of electrostatic charges to deform an oil surface. Origins and use The idea for the original Eidophor was conceived in 1939 in Zurich by Swiss physicist Fritz Fischer, professor at the ''Labor für technische Physik'' of the Swiss Federal Institute of Technology, with the first prototype being unveiled in 1943. A basic patent was filed on November 8, 1939, in SwitzerlandMonika Burri''Der Eidophor-Projektor.''ETH History 1855 - 2005.

Hugo Thiemann
Hugo Thiemann (February 2, 1917 – June 10, 2012) was a Swiss R&D manager and visionary. He was a founding member of the ''Club of Rome''. Life Hugo Ernst Thiemann was born in Heiden, Switzerland, then educated in nearby St. Gallen, Switzerland. He studied electrical engineering at the Swiss Federal Institute of Technology in Zurich (ETH Zurich), graduated in 1939 and got his PhD in 1947. There, he was assistant to Professor Fritz Fischer (physicist), known as the inventor of the Eidophor large-screen video projection system, at the Institute of Technical Physics. Thiemann was leading the Eidophor project from 1941 onwards. He lost an eye during his education according to his autobiography (unpublished). In 1946 he married Marianne Beatrice Sturzenegger. When the Eidophor project was transferred from the ETH to Dr. Edgar Gretener AG, a small Swiss company, he joined this company, which was founded by his former colleague Gretener.
