Brief description: * 16 November 1906 in Cologne † 14 January 1995 in Darmstadt-Eberstadt. 1913 to 1926 he attended the Realgymnasium in Siegen. Already at the age of 17 he built his first radio receiver, which, except for the audio tube, was completely "homemade". The battery part of this receiver can be seen in the Technology Museum, Communications Engineering section. From 1926 to 1932 he studied electrical telecommunications, photography and cinematography at the Technische Hochschule Berlin. From 1926 to 1927, he completed an internship at Siemens

Foreword: * 1903 † 14 February 1986 Wolfgang Ferdermann was employed from 1926 to 1946 as a graduate engineer in Department F 3 of the Telefunken Gesellschaft für drahtlose Telegraphie m.b.H. under the direction of Prof. Fritz Schröter. This department dealt with visual telegraphy and the development of television. Federmann himself worked as a television technician and cameraman for Telefunken. He was involved in the design of the FE series of television receivers, at least the FE I, a cabinet-shaped device first presented to the public at the Radio Exhibition in 1932. He was awarded a gold medal for television at the 1937 World Exhibition in Paris. In 1940 the Telefunken group "Studiotechnik" was dissolved. Only a small part of the group continued to construct television sets for military use, the largest part (probably Federmann) was assigned radio measurement technology (night hunter displays, radar and panoramic observation equipment) as a new area of responsibility. Further biographical information on the professional career can be found in document I. NL 095/162 can be taken. The main duration of the estate of Wolfgang Federmann is 1926-1956, with a focus on the late 1920s (picture telegraphy) and mid-1930s (1936 Olympic Games in Berlin, 1937 World Exhibition in Paris, radio exhibitions, opening of the programme service by the Reichs-Rundfunkanstalt). Thematically, technically oriented documents predominate, the estate contains little personal information. The main focus is on the development of television, the development of tubes and picture telegraphy. Most frequently, photos (and glass slide positives, as these often show identical motifs) and printed journal articles appear in Nachlaß Federmann. The estate was donated to the archive in 1994. It has a scope of 639 units of distortion with a duration of 1917-1994.
