The Telefunken Gesellschaft für wireless Telegraphie mbH (from 1955 Telefunken GmbH ) was a German radio and communications technology company . Telefunken and his successor companies built transmitters and receivers for radio telegraphy , broadcasting and wireless and wired transmission technology . The company, which was jointly founded in 1903 by the two electrical companies Siemens & Halske (S & H) and AEG ( Allgemeine Elektricitäts-Gesellschaft ), held over 20,000 patents , was a leader in the development of radar technology and was the inventor of color television based on the PAL system .

From 1941 Telefunken was a wholly owned AEG subsidiary . After the conversion to TELEFUNKEN AG in 1963, the general electricity company AEG-TELEFUNKEN was created through the merger with the parent company in early 1967 . The company was changed to AEG-Telefunken Aktiengesellschaft in 1979 . After the takeover by Daimler-Benz in 1985, its name changed to AEG Aktiengesellschaft and the remaining Telefunken divisions were transferred to various new companies. AEG AG has ceased to exist in 1996, the year it was deleted from the Frankfurt am Main commercial register .

Until about 2005, former AEG-Telefunken company divisions, which were in the tradition of the earlier Telefunken company, were represented on the market with this name as part of the company. Today the rights to the brand are owned by Telefunken Licenses GmbH , which grants licenses for the use of the term “Telefunken”.

Meanwhile, under the brand name "Telefunken" electrical items are almost available in each category, including clock radios , car radios , chargers , smart phones , washing machines and automated external defibrillators (AED).

At the turn of the century , the two leading electrical companies in the German Reich each had their own laboratories for research into spark telegraphy for wireless communication. One group around Adolf Slaby and Georg Graf von Arco developed for the Imperial Navy at AEG , the other under Karl Ferdinand Braun at Siemens & Halske for the German Army .

When the two large corporations began to dispute over the patents, Kaiser Wilhelm II settled the matter : At his insistence, Siemens & Halske and AEG founded the company for wireless telegraphy, System Telefunken, as a joint venture in Berlin on May 27, 1903 with a share capital of 300,000 marks . The first technical director was Georg Graf von Arco . Telefunken , the company's telegram address , was registered as a trademark on November 11, 1903 at the Imperial Patent Office . When the company was founded, at the beginning of the age of radio and communications technology, the companies S & H and AEG pooled their knowledge and activities to develop and market radio and receiving systems for civil shipping, the military and intercontinental communications. Telefunken was in competition with the Berlin-based C. Lorenz AG and, in the area of merchant shipping, also with the Compagnie de Télégraphie sans Fil (Society for wireless telegraphy) in Brussels, a company founded in 1900 by the British Marconi Company that operates merchant ships in almost all European countries equipped. Radio stations on British ships, on the other hand, were operated by the Marconi subsidiary Marconi International Marine Communication Company , which was also created in 1900 .

For the Seefunkverkehr subsidiary Marconi founded in 1911 Siemens, AEG and Telefunken together with the Brussels Compagnie de telegraphy sans Fil , the German operating company for wireless telegraphy mbH ( DEBEG ), which could use the radio stations of the four companies involved worldwide. With the extinguishing spark transmitters (sound spark transmitters) introduced by Telefunken in 1908 with a range three times greater than the old pop-spark transmitters , the company, together with Marconi, soon assumed a leading role in the operation of marine radio stations. The importance of maritime radio became particularly clear after the sinking of the Titanic in 1912: DEBEG and with it Telefunken had a noticeable increase in sales.

In April 1923 the company was changed to Telefunken Gesellschaft für wireless Telegraphie mbH and maintained for over 30 years until 1955. From 1923 Telefunken started building radio transmitters and receivers. With the advent of broadcasting , the years from 1924 to the Great Depression in 1929 were particularly strong in sales.

At the 5th Great German Radio Exhibition in Berlin in 1928, the company exhibited television sets working according to the projection method . In 1930, the Telefunken employee Fritz Schröter invented the interlacing process for flicker-free images. From 1932 experimental television broadcasts were carried out together with the Reichspost . With the subsidiary Telefunken-Platte GmbH founded in 1932 (from 1950 Teldec until its sale to the Time Warner Group in 1987 ), Telefunken was also one of the largest German companies in the record industry . From 1933, the company produced in collaboration with Oskar Sala the Trautonium , an electronic musical instrument . It was advertised for house music , but did not catch on. With the young jazz musician Heinz Wehner , the record company built an international star from 1935 and, regardless of the measures imposed by the Reichsmusikkammer , played an American-style big band with Wehner's “Telefunken Swing Orchestra” .

The "target flight devices" developed by Telefunken from 1934, together with the Lorenz landing system introduced by the Berlin company C. Lorenz AG, are the forerunners of today's instrument landing systems (ILS).

The German standard television receiver equipped with a new type of rectangular picture tube from Telefunken was developed together with other companies in the broadcasting industry and presented in 1939 at the 16th German Radio and Television Exhibition in Berlin. In the same year, the company took over the Osram plant A (like AEG; the former AEG incandescent lamp factory) in Sickingenstrasse 71 (Berlin-Moabit) in order to continue producing the technologically important electron tubes under its own management. Osram had manufactured the tubes for Telefunken there since 1920. In this largest tube factory in Europe alone, including ancillary companies, around 8,000 people were employed in 1939, producing up to 12 million electron tubes annually, which represented three quarters of German demand.

At the end of the 1930s, the total workforce was 23,500 and increased to 40,000 in the course of the Second World War ; including, as in almost all large German companies, many forced and " Eastern workers ". In 1941, AEG took over the Telefunken shares from S & H (Siemens & Halske) and continued to run the company as a wholly owned subsidiary. S & H got permission to continue using the Telefunken patents until the end of the war .

Before and during the war, the Telefunken Society was the leading German company in the field of electronic warfare, especially radio measurement technology , as the Wehrmacht called the newly introduced radar devices for camouflage. In addition to various direction finders for targeting, the " Knickebein " beacon system and the " Bernhard " radio beacon for general flight navigation were developed for the Air Force . Telefunken introduced fixed radars ( " Würzburg " and " Würzburg-Riese "), decimeter - radio relay systems ( "Michael" device) and the first passive radar " Klein Heidelberg " her. The company developed the first German aircraft on-board radar "Lichtenstein" for night hunting . In order to warn the submarines of the Kriegsmarine about the Allied submarine fighters equipped with centimeter wave radar ( H2S ), Telefunken delivered the radio monitoring device "Naxos" . The short-signal procedure "courier" made it almost impossible for the enemy to locate radio stations that sent messages.

After the Second World War - merger with AEG in 1967

After the war, three important locations in Berlin had failed: the "Telefunken house" at the hall Ufer  30 burned during the fighting in the city and in the Allied air raids was the building Belle-Alliance-Str. 7–10 (today Mehringdamm 32/34) in Kreuzberg was badly damaged, as was the main factory in Zehlendorf . The latter was completely dismantled and used by the US Army as a barracks ( McNair Barracks ) for the Berlin Brigade until 1994 . Only the electron tube plant in Moabit and the Schwedenstrasse device plant in Wedding were still available. The factories located in Thuringia, Saxony and Silesia came under Soviet ( SMAD ) and Polish administration. In autumn 1945, tube receivers began to be manufactured in the renovated barracks of the former Dachau concentration camp under the name Apparatewerke Bayern, Dachau . From autumn 1946 onwards, Telefunken gradually relocated this production to Hannover-Ricklingen in the building of the Huth-Apparatefabrik at Göttinger Chaussee 76, which was built in 1940/41 according to plans by Ernst Zinsser for the production of radio technology for the Wehrmacht. From 1951, Telefunken also produced the first FE 8 television set newly developed after the war there .

At the beginning of the 1950s, various business areas were relocated from West Berlin to West Germany ( Ulm and Backnang ) and existing production facilities were taken over, expanded or newly established in order to a. to be active again in the newly emerging business of civil and military radar technology . According to the occupation statute , these activities were prohibited in Berlin. Telefunken developed under the “heavy current parent” AEG into the “low current subsidiary” with the three business areas of news and data technology ( analog / digital computers ), components as well as radio , television and phono . Telefunken had considerable success in these markets during the period of independence and later in the AEG group.

The company's name was changed to Telefunken GmbH in 1955 because wired technology had also been added to wireless technology. In 1963 the company was converted to Telefunken Aktiengesellschaft .

With a special permit from the English control authority, license production of Decca navigation systems for shipping was started in 1951. From 1955 onwards, after a ten-year break due to the Paris agreements , the company was able to operate again without restrictions in radar technology and built the GCA technology ( ASR surveillance systems and PAR systems ) under license from the US for civil aviation on behalf of the Federal Agency for Air Traffic Control. Company Bendix Corporation . Later, medium-range radar systems followed as in-house developments until this line of business was discontinued in 1984 (see also: SRE-M ). The port of Hamburg radar system was set up for shipping between 1958 and 1962 . Further systems on the Elbe, Jade, Weser and on Helgoland followed. As a license- produced Telefunken in Ulm also NASARR-radar (North American Search and Ranging Radar) for the Lockheed F-104 "Starfighter" the Bundeswehr .

At the Essen police fair in September 1956, Telefunken presented the VRG (traffic radar device ), a device that was required to monitor the newly introduced speed limits (initially 50 km / h in localities from September 1, 1957).

In 1956, Telefunken's long-distance systems division (AW) began developing the mainframe computer TR 4 in Backnang , which was presented to the public in 1962 at the Hanover Fair . The first series system was put into operation in 1962 at the Institute for Applied Mathematics at the University of Hamburg . The TR 4 and its successor TR 440 (read: four-forty), developed in the mid-1960s at the Information Technology Department in Konstanz , were in use at many German university computer centers until around 1985. In cooperation with Nixdorf Computer AG , the new Telefunken Computer GmbH (TC) based in Constance took over the AEG-Telefunken mainframe development and production in 1971. In 1974 the TC became the Computer Gesellschaft Konstanz (CGK). The area of ​​medium-sized computers and process computers became part of AEG's automation technology division.

In 1959 Telefunken built a modern semiconductor factory in Heilbronn , where production began in April 1960. The plant was expanded several times, for example in 1970 with a six-story new building on the northern edge of the site. Around 2500 people worked there at the beginning of the 1970s.

For the production of color television receivers, a factory was opened in the Hehlentor district of Celle in 1966 , where up to 2,800 people found work in the 1970s. In contrast to the NTSC color system introduced in the USA in 1953, the analog PAL color television system, developed in the company's own basic television laboratory in Hanover under the leadership of Walter Bruch and registered for a patent in 1962, contains a technology for automatic error correction of color distortions. The color coding of the PAL system is still used in all digital televisions that support this standard.

The independent existence of Telefunken ended at the beginning of 1967: The parent company AEG merged with Telefunken AG, Berlin and Ulm under the name Allgemeine Elektricitäts-Gesellschaft AEG-TELEFUNKEN , based in Frankfurt / Main. Around 34,600 Telefunken employees moved with the last Telefunken CEO, Felix Herriger, to the new group headed by Hans Bühler (1903–1997). Until the company changed to AEG-Aktiengesellschaft, Telefunken and AEG remained on the buildings for another 18 years.

The entertainment electronics division (radio and television equipment) was spun off in 1972 into the independent TELEFUNKEN Fernseh und Rundfunk GmbH based in Hanover. The French state-owned Thomson Group took over this in 1983/84 and the subsidiaries Thomson Consumer electronics and Thomson multimedia subsequently used the Telefunken brand as a trade name .

The Allgemeine Elektricitäts-Gesellschaft AEG-TELEFUNKEN became AEG-TELEFUNKEN Aktiengesellschaft in 1979 . For reasons of EC law , the company form AG had to be added. At the same time the name Allgemeine Elektricitäts-Gesellschaft , which had existed since 1888, was dropped .

Economic difficulties of the AEG group forced the outsourcing of business areas, the participation of third parties in business areas or the later sale from around 1970. An extraordinary general meeting in January 1980 initially resolved a capital reduction of the existing shares by 3: 1 with a subsequent capital inflow of 1,682 million DM of new funds. Walter Cipa's successor (AEG Chairman since 1976) was succeeded by Heinz Dürr .

High losses in individual areas, etc. a. in the television and radio business, forced sales of entire business areas or shares in distress as early as 1981, such as at AEG-Telefunken Nachrichtenentechnik GmbH (ATN) in Backnang, of which a consortium of Thomson , Bosch , Mannesmann and Allianz -versicherung took over a part . In the following year 1982 the Telefunken shares of Teldec (until 1950 "Telefunken-Platte") were sold to a Swiss holding company. The semiconductor business in Heilbronn was operated from 1982 with a 51 percent majority by the US group United Technologies Corporation as a joint venture company, initially as Telefunken electronic GmbH, and since 2001 has belonged to Conti temic microelectronic based in Nuremberg. ATN in Backnang was completely taken over by the other shareholders in 1983 and continued under the name ANT until 1995 (from 1995 Bosch Telecom ; from February 1, 2000 Marconi Communications GmbH; from 2006 Ericsson and telent GmbH).

In the course of the settlement proceedings of the AEG from August 1982 to October 1984, further essential core areas were transferred. The loss-making TELEFUNKEN Fernseh und Rundfunk GmbH was bought by the French Thomson-Brandt group in 1983/84 . A reorganization plan that provided for federal guarantees of 600 million DM and new bank loans of 275 million DM failed due to the disagreement of the banks. A consortium of banks granted the AEG group an administrator loan of DM 1.1 billion until June 1983. Of this amount, DM 700 million was immediately available and DM 400 million after a guarantee by the federal government. The settlement administrator was the lawyer Wilhelm Schaaf.

In 1985 the group changed its name to AEG Aktiengesellschaft and in the same year the majority was taken over by Daimler-Benz AG . From 1987 the new Daimler board member Edzard Reuter merged the two companies into an "integrated technology group" and operated the sale or outsourcing of several AEG and Telefunken divisions.

The high-frequency division of AEG in Ulm, which belonged to Telefunken until 1966, as well as the shipbuilding and special technology sector (defense technology) in Hamburg and Wedel and Telefunken microelectronics GmbH in Heilbronn, became Deutsche Aerospace AG ( DASA ) in Munich in 1989 with Dornier , MTU and MBB merged by Jürgen Schrempp .

In the same year, the former Telefunken High Frequency Technology Ulm division became part of the DASA Defense Technology division under the name Telefunken Systemtechnik GmbH , together with Telefunken Sendertechnik GmbH Berlin . The voice and data radio business in Ulm was initially operated as a 100 percent AEG subsidiary, AEG Mobile Communication GmbH , which in May 2002 became part of EADS Racoms (Radio Communication System), which was founded in 2000 . In 2004, EADS Radio Communication System GmbH & Co. KG was taken over by Elbit Systems and renamed TELEFUNKEN Radio Communication Systems GmbH & Co. KG (Telefunken Racoms) .

The mobile communications division of AEG Mobile Communication was initially transferred under the name Matra Communication Cellular Terminals to a joint venture between Matra and later also Nortel . The development department in Ulm on the Obere Eselsberg was taken over by Nokia in 1998 . The development of mobile radio devices under the brand name AEG was ended and for the new owner Nokia, GSM fixed-mounted telephones and telematics terminals were initially developed for almost all leading car manufacturers (Ford, Volkswagen, Mercedes, Opel). These products were bundled in the Smart Traffic Products division . The development took place together with the Nokia location in Bochum, the production also in the Nokia factory in Bochum. After a reassessment of the market priorities, the development of Smart Traffic Products terminals in Ulm was terminated in 2002 and the development of Nokia cell phones was started, which continued until the site was closed in 2012.

16 years earlier, on September 20, 1996, the company of the traditional, former parent company AEG was deleted from the commercial register.

At the Heilbronn location, the semiconductor production taken over by Atmel was sold to Tejas Silicon Germany GmbH & Co KG , which acquired the rights to the Telefunken name on January 1, 2009, and integrated circuits at this location under the Telefunken Semiconductors GmbH & Co. KG company as a foundry . The company filed for insolvency in April 2013 due to over-indebtedness. After the second application in August 2014, the insolvency administrator could not find an investor to continue the company and operations ceased on the last working day on February 27, 2015.

The name Telefunken is used today

Some of Telefunken's areas of work were continued in successor companies, most of which have since been completely discontinued. The term “Telefunken” was used until 2005 as part of the company that was outsourced or sold by the former AEG. In 2005, Telefunken SenderSysteme Berlin AG , which had been in existence since 2000 and initially operated as Telefunken Sendertechnik GmbH from 1989, changed its name to TRANSRADIO SenderSysteme Berlin AG . The name “Transradio” can be traced back to 1918 - with the introduction of duplex traffic for radio links in 1919, Transradio-Aktiengesellschaft for wireless overseas traffic gained worldwide recognition. TRANSRADIO SenderSysteme Berlin AG specializes in research, development and construction of AM , VHF / FM and DRM transmitters, as well as commercial and military communication transmitters for long and long wave .

In 1995, Daimler-Benz AG transferred the remaining assets of the AEG-Telefunken group to EHG Electroholding GmbH , thus ending the history of both companies. As a brand , "Telefunken" is still present with over 50 partners in over 120 countries; the products offered under this name only have the name in common with the original company. The use of the term “Telefunken” by various companies is based on license agreements. The Daimler AG sold the Telefunken brand rights in December 2007 to the Live Holding AG in Berlin. The CEO of Live Holding is the former Lufthansa and Deutsche Bahn board member Hemjö Klein, who is also chairman of the supervisory board of the subsidiary Telefunken Licenses GmbH in Frankfurt am Main, which was founded in 2008 . Since then, the company has been granting the trademark and license rights associated with the term "Telefunken". Telefunken Licenses is a subsidiary of Telefunken Holding AG .

In August 2006 the Turkish company Profilo-Telra, one of the largest European manufacturers of TV sets, received a license from the French Thomson AG to sell TV sets in various European countries under the TELEFUNKEN brand. Thomson AG had the license to use the brand name for its part from Telefunken Licenses GmbH , Frankfurt a. M. received. Until December 2007, this was part of Daimler AG as a subsidiary of EHG Elektroholding GmbH , Frankfurt am Main . In April 2008 the collaboration with Profilio-Telra was ended. Telefunken televisions are currently (2011) mostly manufactured by Vestel in Turkey .

Since 2008 offers Telefunken AutoTainment in replacement demand market entertainment center specially for vehicles of the Volkswagen Group at. Telefunken Solar markets photovoltaic systems in the German market .

Telefunken Elektroakustik in the USA manufactures replicas of high-quality microphones that were previously sold under the Telefunken brand, as well as its own new developments. These included microphones from the brands AKG (Austria), Neumann (FRG) and Neumann Gefell (GDR).

Telefunken Racoms has been a wholly owned subsidiary of Elbit Systems since 2004 and offers technical systems for communication and reconnaissance in the armaments and security sector.

Business areas

From 1903 to 1996, a wide range of components, devices and systems was developed and produced in the Telefunken factories and in the departments that were transferred to AEG-TELEFUNKEN. The common hallmark was the competence for high frequency and communication technology and the necessary infrastructure in the area of ​​component production. Amongst other things:

The company headquarters was initially Besselstrasse. 21 in Berlin-Kreuzberg ; in the following period until 1918 the building at Tempelhofer Ufer 9 in Berlin-Kreuzberg. Until the 1930s, the two parent companies manufactured the Telefunken products in their own factories according to a distribution formula. Telefunken did not develop its own electronic tubes until 1914 under the direction of Hans Rukop ; In  1917, a dedicated production facility was set up for this purpose in the Friedrichstrasse 235 building in Berlin-Kreuzberg. This was closed again in 1920 and Osram GmbH KG , a joint venture between Siemens & Halske , AEG and Deutsche Gasglühlicht AG , built the electron tubes for Telefunken in their incandescent lamp factory in Sickingenstrasse in Berlin-Moabit . From 1918 to 1937 the Telefunken company headquarters was in the "Telefunkenhaus", Hallesches Ufer 30 in Berlin-Kreuzberg, which from 1932 to 1937 was also the seat of the subsidiary Telefunken-Platte .

From 1938 37 Berlin locations were combined in the Telefunkenwerk Zehlendorf in Zehlendorf (postal address at that time: Vierter Ring / Osteweg , today's area between Goerzallee and Platz des 4. Juli in Lichterfelde ). The plant, which was built from 1937 to 1940 according to plans by the architect Hans Hertlein , last had 90,000 m² of floor space and was the company's headquarters until 1945.

Before and during the Second World War there were other factories in addition to Berlin, some under the direction of the parent company AEG, in Neuhaus am Rennweg (1936, electron tubes), two in Erfurt (1937 device factory, 1939 electron tubes), Saxony, Moravia, Silesia (Breslau, Liegnitz and Reichenbach in the Owl Mountains ) and on Rügen. In many cases, Telefunken devices were also manufactured for the Wehrmacht by other companies such as the Sachsenwerk in Radeberg . In the occupied areas of the Baltic and Poland, such as Reval, Riga ( AEG "Ostlandwerk" ), Posen, Krakow (radio equipment ) and Łódź (then Litzmannstadt ) there were also production facilities. Forced workers or " Eastern workers " were employed in many of these plants . The Litzmannstadt pipe works was moved together with the workforce to Ulm ( Wilhelmsburg Fortress ) in August 1944 .

The Zehlendorf plant was confiscated by the American occupation forces in 1945, was US headquarters until 1949 and US barracks ( McNair Barracks ) until 1994 , later redesigned as a residential complex. In April 1945 the Hallesches Ufer 30 building ("Telefunkenhaus") burned down completely and was not used again later. The company headquarters was therefore initially in Maxstr. 8 (receiving laboratory in Schöneberg / today Kärntener Str.) And in 1948, after the war damage had been repaired, moved to the company's own house in Mehringdamm 32/34 (until 1947: Belle-Alliance-Str. 7-10) in Kreuzberg. This building was sold after 1955.

1952–1960 the company headquarters was the factory for electron tubes in Sickingenstrasse. 71 ( Berlin-Moabit ). In 1960, the Telefunken skyscraper on Ernst-Reuter-Platz in Berlin-Charlottenburg was used as the new headquarters and remained so until the merger with AEG in 1967. From the beginning of the 1950s, new development and production sites were increasingly built or built in West Germany. adopted because the Allied Control Council Act No. 25 continued to contain a strict ban on all military research for Berlin. This also included activities in the field of radar and high frequency research, which were to be resumed at Telefunken.
