Telefunken
Telefunken was a German radio and television producer, founded in Berlin in 1903 as a joint venture between Siemens & Halske and the ''AEG (German company), Allgemeine Elektrizitäts-Gesellschaft'' (AEG) ("General electricity company"). Prior to World War I, the company set up the first world-wide network of communications and was the first in the world to sell electronic televisions with cathode-ray tubes, in Germany in 1934. The brand had several incarnations: * ''Gesellschaft für drahtlose Telegraphie Gesellschaft mit beschränkter Haftung, m.b.H., System Telefunken'', founded in 1903 as a joint venture between AEG and Siemens & Halske * ''Telefunken, Gesellschaft für drahtlose Telegraphie m.b.H.'', in 1923; since 1941 as subsidiary of AEG alone * ''Telefunken Gesellschaft mit beschränkter Haftung, GmbH'', in 1955 * ''Telefunken Aktiengesellschaft (AG)'', in 1963 * ''Allgemeine Elektrizitäts-Gesellschaft AEG-Telefunken'', created in 1967 through a merger between Telefunken ...

AEG (German Company)
; AEG) was a German producer of electrical equipment. It was established in 1883 by Emil Rathenau as the ''Deutsche Edison-Gesellschaft für angewandte Elektricität'' in Berlin. The company's initial focus was driven by electrical lighting, as in 1881, Rathenau had acquired the rights to the electric light bulb at the International Exposition of Electricity in Paris. Using small power stations, his company introduced electrical lighting to cafés, restaurants, and theaters, despite the high costs and limitations. By the end of the 19th century, AEG had constructed 248 power stations, providing a total of 210,000 hp of electricity for lighting, tramways, and household devices. During the World War II, Second World War, AEG worked with the Nazi Party and benefited from forced labour from concentration camps. After the war, its headquarters moved to Frankfurt am Main. In 1967, AEG joined with its subsidiary Telefunken, Telefunken AG, creating ''Allgemeine Elektricitäts-Ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karl Ferdinand Braun
Karl Ferdinand Braun (; ; 6 June 1850 – 20 April 1918) was a German physicist, electrical engineer, and inventor. Braun contributed significantly to the development of radio with his 2 circuit system, which made long range radio transmissions and modern telecommunications possible, and with his invention of the phased array antenna in 1905, which led to the development of radar, smart antennas, and MIMO. Before that, he built the first cathode-ray tube in 1897, which led to the development of television, and the first semiconductor device in 1874, which co-started the development of electronics and electronics engineering. Braun shared the 1909 Nobel Prize in Physics with Guglielmo Marconi "for their contributions to the development of wireless telegraphy". He was a founder of Telefunken, one of the pioneering communications and television companies, and has been called the "father of television" (shared with inventors like Paul Gottlieb Nipkow), the "great grandfather o ...

Georg Von Arco
Georg Wilhelm Alexander Hans Graf von Arco (30 August 1869 in Gorzyce, Silesian Voivodeship, Großgorschütz – 5 May 1940 in Berlin) was a German physicist, radio pioneer, and one of the joint founders of the "''Society for Wireless Telegraphy''" which became the Telefunken company. He was an engineer and the technical director of Telefunken. He was crucial in the development of wireless technology in Europe. Arco served for a time as an assistant to Adolf Slaby, who was close to William II, German Emperor. Until 1930, Arco was one of the two managing directors of the company. He participated in the development of high performance vacuum tube, tube transmitters. Together with his teacher, Slaby, he was considerably involved in the study and development of high-frequency engineering in Germany. He was a Monist and a pacifist. Between 1921 and 1922, he was a chairman of the German Monist Federation. Early years Arco was born on the estate of his father, Count Alexander Kar ...

Cathode-ray Tube
A cathode-ray tube (CRT) is a vacuum tube containing one or more electron guns, which emit electron beams that are manipulated to display images on a phosphorescent screen. The images may represent electrical waveforms on an oscilloscope, a Film frame, frame of video on an Analog television, analog television set (TV), Digital imaging, digital raster graphics on a computer monitor, or other phenomena like radar targets. A CRT in a TV is commonly called a picture tube. CRTs have also been Williams tube, used as memory devices, in which case the screen is not intended to be visible to an observer. The term ''cathode ray'' was used to describe electron beams when they were first discovered, before it was understood that what was emitted from the cathode was a beam of electrons. In CRT TVs and computer monitors, the entire front area of the tube is scanned repeatedly and systematically in a fixed pattern called a raster scan, raster. In color devices, an image is produced by con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adolf Slaby
Adolf Karl Heinrich Slaby (18 April 1849 – 6 April 1913) was a German electronics pioneer and the first Professor of electro-technology at ''Technische Hochschule Charlottenburg'' (today Technische Universität Berlin, 1886). Education Slaby was born in Berlin, the son of a bookbinder. He studied at ''Berliner Gewerbeakademie'', the predecessor of ''Technische Hochschule Charlottenburg'' to study mechanical engineering and mathematics under Franz Reuleaux. He was employed as a housekeeper with the machine manufacturer Louis Schwartzkopff, leading to an interest in mechanical engineering. Slaby continued his studies at the University of Jena, and received his doctorate in mathematics. Early research Slaby taught mathematics and mechanics at a vocational school at Potsdam, where he conducted experiments on steam engines and petrol engines. He wrote his book ''Theorie der Gasmaschinen'' (Theory of Gas Engines), which had an important part in the development of Internal combu ...
