The company Lorenz exists since 1870. In that year Carl Lorenz started a mechanical workshop in Berlin. In 1880 a company named Telegraphenbauanstalt, Fabrik für elektrisches Licht, elektrische Eisenbahnen, Kunst und Industrie was founded.

In 1938 the production of DKE38 People's Receivers starts, after Lorenz has won the competition for a cheap radio.

In 1940 Lorenz takes over company G. Schaub Apparatebau GmbH.

After the war Lorenz starts anew and in 1948 the company headquarters move from Berlin to Stuttgart-Zuffenhausen. There are several braches by that time: Berlin-Tempelhof (wireless- and broadcasting technique), Esslingen (valves), Landshut (electrical machines, broadcasting equipment and signal technique), Pforzheim I (development laboratory and model workshop for different forms of small-scale transmitting equipment), Pforzheim II (telex factory) and Schaub Pforzheim (radio- and television receivers). In the eastern part of Germany the production of radios goes on for some time, but ceases in 1947.

In the beginning of the fifties, Lorenz starts making wire recorders, mostly integrated into radios. In 1954 the brand name of radios and televisions is changed to Schaub-Lorenz. In 1958 Lorenz teams up with Standard Elektrik AG as Standard Elektrik Lorenz AG (SEL). In 1961 the company also becomes the major shareholder of radio firm Graetz.

In 1975 some sectors experience losses and Alcatel, that has the majority of shares, moves part of the activities to Nokia in the 1980's. Nokia still uses the brand names Schaub-Lorenz and Graez.

After his death in 1890 the company was bought by textile salesman Robert Held. After the takeover of the company Telegraphen-Bauanstalt C.F. Lewert in 1906, the name of the firm was changed in C. Lorenz A.G. From that time on the company was allowed to use the Poulsen arc transmitter system. In order to optimise these activities a wireless telegraphy department was formed.

In 1920 Lorenz started the first radio broadcasting in Germany with a Lorenz-Poulsen-transmitter. Lorenz also gives amateurs and employees the possibility to receive and transmit.

In 1923 the first receiver is introduced: the Liebhaber-Empfänger.

In 1924 Robert Held dies. The company employs more than 3000 worker and is active in a number of fields. In 1929 Lorenz makes radios for Philips for a short while, but has to stop in 1930, because of a conflict with Telefunken. In the same year company Tefag is taken over. The brand name Tefag is used until the Second World War. Valve making stops for a while in 1932.

In 1935 Lorenz patents the ferrite sounding antenna; this invention is widely used in radios later on. In 1937 Lorenz starts producing radio valves again for the German Army.

ITT Schaub-Lorenz

Company history

G. Schaub Apparatebau - Gesellschaft mbH was founded in 1925 in Berlin-Charlottenburg and initially manufactured detector and valve receivers. In 1934, the production was moved to Pforzheim. In 1941, the company is integrated into Conrad Lorenz AG, Berlin, and adapted to wartime production; after a bombing raid, the factory burned out in February 1945.

In 1946, production was resumed. During the years of the Berlin blockade, the production was transferred entirely to Pforzheim and in 1956 the name was changed to Schaub-Lorenz. ITT wook over some of the export tasks.

In 1958, Schaub-Lorenz was merged with other companies to form Standard Elektrik Lorenz AG (SEL), and a new production plant started operations in Rastatt in 1959, with production there continuing until 1978.

The ITT Schaub-Lorenz division, founded in 1979, was sold by ITT in 1986 to the French CGE, which sold it to Nokia in 1988, shortly after, production came to an end.
