History

Image:Triode REN904.jpg from 1930, used in early German radios.]] Image:Telefunken Digitale 45.jpg ]] Around the turn of the 20th century, two groups of German researchers worked on the development of techniques for wireless communication. The one group at AEG, led by Adolf Slaby and Georg von Arco developed systems for the German navy; the other one, under Karl Ferdinand Braun, at Siemens, for the German army. When a dispute concerning patent arose between the two companies, Kaiser Wilhelm II decided that the two companies were to be joined, creating on 27 May 1903 the company Gesellschaft für drahtlose Telegraphie System Telefunken "The Company for Wireless Telegraphy Ltd."), and the disputed patents and techniques were invested in it. This was then renamed on 17 April 1923 as Telefunken, The Company for Wireless Telegraphy Telefunken was the companys telegraph address. The first technical director of Telefunken was George Graf von Arco. Starting in 1923, Telefunken built broadcast transmitters and radio sets. In 1928, Telefunken made history by designing the V-41 amplifier for the German Radio Network. This was the very first two stage, "Hi-Fi" amplifier which began a chapter in recording history. Over time, Telefunken perfected their designs and in 1950 the V-72 amplifier was born. The TAB (a manufacturing subcontractor to Telefunken) V-72 soon became popular with other radio stations and recording facilities and would eventually come to help define the sound of most European recordings. The V-72S was the only type of amplifier found in the legendary REDD-37 console used by the Beatles at Abbey Road Studios on every recording prior to Rubber Soul Today the V-72 is still the most sought after example of Telefunkens design and over 50 years later continues to be the benchmark by which all other tube based microphone preamplifiers are measured. In 1932, record players were added to the product line. In 1941 Siemens transferred its Telefunken shares to AEG as part of the agreements known as the "Telefunken settlement", and AEG thus became the sole owner and continued to lead Telefunken as a subsidiary (starting in 1955 as "Telefunken GmbH and from 1963 as "Telefunken AG"). During the Second World War Telefunken was a supplier of vacuum tubes, transmitters and radio relay systems, and developed radar facilities and directional finders, aiding the war efforts of the Third Reich. During the war, manufacturing plants were shifted to and developed in West Germany or relocated. Thus, Telefunken, under AEG, turned into the smaller subsidiary, with the three divisions realigning and data processing technology, elements as well as broadcast, television and phono. Telefunken had substantial successes in these markets during the time of self-sufficiency and also later in the AEG company. Telefunken was also the originator of the FM radio broadcast system. Telefunken, through the subsidiary company Teldec (a joint venture with Decca Records , was for many decades one of the largest German record companies, until Teldec was sold to Warner Music Group in 1988. In 1959, Telefunken established a modern semiconductor works in Heilbronn where in April 1960 production began. The works was expanded several times, and in 1970 a new 6-storey building was built at the northern edge of the area. At the beginning of the 1970s it housed approximately 2,500 employees. In 1967, Telefunken was merged with AEG, which was then renamed to AEG-Telefunken. During this era, Walter Bruch developed the PAL color television for the company, in use by most countries outside the Americas today (i.e. Television in the UK - PAL-I), and by Brazil (PAL-M) and Argentina (PAL-N) in South America. The mainframe computer TR 4 was developed at Telefunken in Backnang, and the TR 440 model was developed at Telefunken in Konstanz. They were in use at many German university computing centres from the 1970s to around 1985. The development and manufacture of large computers was separated in 1974 to the Konstanz Computer Company (CGK). The production of mini- and process computers was integrated into the automatic control engineering division of AEG. When AEG was bought by Daimler AG in 1985, "Telefunken" was dropped from the company name. In 2005, Telefunken Sender Systeme Berlin changed its name to [[Transradio]] SenderSysteme Berlin AG The name "Transradio" dates back to 1918, when Transradio was founded as a subsidiary of Telefunken. A year later, in 1919, Transradio made history by introducing duplex transmission. Transradio has specialized in research, development and design of modern AM broadcasting Very high frequency Frequency modulation and Digital Radio Mondiale broadcasting systems. In August 2006, it acquired the Turkish company Profilo Telra, one of the largest European manufacturers of TV-devices, with Telefunken GmbH granting a license for the Telefunken trademark rights and producing televisions under that name. In 2000, Toni Roger Fishman acquired The Diamond Shaped Logo & The Telefunken Brand Name for use in North America. The company "Telefunken USA" http://www.telefunkenusa.com] was incorporated in early 2001 to provide restoration services and build reproductions of vintage Telefunken microphones. In 2003, Telefunken USA won a TEC Awards for Studio Microphone Technology for their exact reproduction of the original Ela M 250 / 251 Microphone system. Telefunken USA has since received several TEC Awards nominations for the following microphone systems: the Telefunken USA M12 or C12 (originally developed by AKG), the R-F-T M16 MkII, and the AK47. The Historic Telefunken Ela M251 microphone system entered the MIX foundations Hall of fame in 2006. In 2008, Telefunken USA won a second TEC Award for its new Ela M 260 microphone. As a result of a conference held in Frankfurt in May 2009, Telefunken USA has been renamed Telefunken Elektroakustik ("Electrical Acoustics") Division of Telefunken and awarded the exclusive rights to manufacture a wide variety of professional audio products and vacuum tubes bearing the Telefunken Trade Mark, in over 27 countries worldwide. Telefunken Elektroakustik now uses the Telefunken trademark for Professional Audio Equipment & Component Based Electronics, such as Capacitors, Transformers, Vacuum Tubes in North America, South America, Europe, Asia and Australia.

Locations and manufacturing plants

Into the 1930s years, production was made after a distributor in the workshops of the two parent companies. The company headquarters was in Berlin Kreuzberg, Hallesches Ufer 30 (1918–37). Starting from 1938, manufacturing and developing plants were concentrated at the new headquarter (until 1945) in Berlin Zehlendorf, Goerzallee. During the Second World War, there were further manufacturing plants in the Berlin area, in Thuringia, Saxonia, Mähren, Schlesien, on Rügen. In addition, in occupied areas of the Baltic and in Poland at Tallinn, Riga, Krakau, floats and Łódź works were established also with forced laborers. The tube mill Łódź was shifted in 1944 with the staff from Ulm. After the Second World War, new firm locations for development and production were established. The company headquarters was located first in Berlin-Schöneberg (1945–48), then in Berlin-Kreuzberg (1948–52), Berlin-Moabit (1952–60), Berlin Charlottenburg (1960–67). Production plants were located in: * Backnang Long-distance communications and cable technology * Berlin Moabit Sickingenstr. 20-26: Broadcast and television transmitters, mobile communications * Berlin Moabit Sickingenstr. 71: Tubes * Berlin Reinickendorf Schwedenstr.: Phono and tape decks * Nohfelden High-frequency engineering * Hanover Göttinger Chaussee 76: Broadcast and television sets * Heilbronn Semiconductor, circuits, solar cells, infrared modules * Konstanz Computer technology, letter sorting systems, character recognition technology, air traffic control systems, Studio tape decks, cash dispensing machines * Offenburg Long-distance communications technology * Ulm Danube valley: Television picture tubes * Ulm, Elisabethenstrasse: Radar, Radiolocation, detection equipment, speech and radio data transmission systems, Research Centre * Ulm, Söflinger Strasse: Tubes * Wolfenbüttel Electroacoustics
