Certo Dollina III camera: "F. Deckel - Munich"

The Friedrich cover AG was one of Germany's largest manufacturer of camera shutters and machine tools . The company was based in Munich Sendling at 150 Plinganserstraße.

Company history

The precision mechanic from Jungingen , Friedrich Deckel, worked as a laboratory mechanic at the Zeiss company in Jena from 1889 under the personal guidance of Ernst Abbe , one of the founders of the Zeiss company. At the end of 1898, Deckel went into business for himself with a mechanic's workshop and in 1903 founded the company "Bruns & Deckel" in Munich together with the inventor Christian Bruns . Bruns developed the compound - shutter , which the company in 1904 produced and marketed. Bruns left the company as early as 1905, but continued to develop closures for cameras. Friedrich Deckel thus became the sole owner of the company now trading as "Friedrich Deckel GmbH" .

The companies Carl Zeiss , Bausch & Lomb and Alfred Gauthier became co-partners in 1910. In 1911, Carl Zeiss acquired the patents for the new Compur lock from Christian Bruns . Zeiss had the closure of the lid manufactured under license. The Compur lock had a newly developed wheel escapement for slow shutter speeds.

Friedrich Deckel's own need for high-precision machine tools for precision mechanics and mold making was largely covered by Lid himself. Such special machines could hardly be bought at that time and were therefore designed and manufactured by Deckel itself. This led to the decision of the company in 1911 to offer the self-made machines to the companies of the camera and optics industry in Munich, which are interwoven with a lid. Lid increasingly supplied machines and closures to other well-known camera manufacturers, such as the Agfa Camerawerk in Munich. Over the years, the subsidiary business of special machine construction became the company's core business.

In 1912, the Deckel company was the first company in Munich to introduce the eight-hour day, and in 1914 the company already had 500 employees.

From 1924, Deckel also manufactured injection pumps for diesel and gasoline engines , as well as for the BMW 801 aircraft engine built from 1940 .

At the beginning of the 1950s, Deckel designed the concept of the Light Value Scale (LVS), also known as the Exposure Value Scale (EVS), and propagated light-value-coupled closures as a general standard. Such closures were used from 1954 by Rollei , Hasselblad , Voigtländer , Braun , Kodak and others, e.g. Sometimes in connection with a lens quick -change mount , which is also based on a cover, the so-called cover or DKL bayonet in different mechanically slightly incompatible variants. The light value principle was also taken up by the American APEX system in 1960 .

In 1953 the company had 3,000 employees and from the late 1950s onwards increasingly concentrated on machine tool construction. Especially the milling machines of the FP series, especially the FP1, achieved world fame as universal, high-precision and excellently finished machines. The more than comprehensive range of accessories and the open design of the FP1, which made it possible to adapt it to almost all production tasks, contributed to the widespread use of this milling machine in test and tool construction as well as in production.

In 1961, the company was renamed “Compur-Werk GmbH & Co.” .

Until 1972, the company now operating as "Friedrich Deckel Präzisionsmechanik und Maschinenbau KG" was the fourth largest manufacturer of machine tools in West Germany. In the same year the company was transformed into "Friedrich Deckel Aktiengesellschaft" .

With the exception of a few variants for Hasselblad cameras with Zeiss lenses, the production of camera shutters was discontinued in 1973, and finally in 1976. The Prontor factory of Alfred Gauthier in Calw took over the production of the closures .

In 1993, Deckel AG merged with Maho AG to form Deckel Maho AG , which, however, filed for bankruptcy just one year later, in 1994. In 1994 Gildemeister took over Deckel Maho AG, which had got into trouble, continued its milling machine concept and then operated under the name DMG (Deckel Maho Gildemeister). Today DMG is part of DMG Mori AG .
