Preface: Karl Mey * 16 March 1879 in Wandersleben near Gotha, Thuringia; † unknown, after May 1945 Mey studied mathematics and physics at the Humboldt University Berlin. He received his doctorate in 1902 with his work "On the cathode gradient of alkali metals". After completing his studies, Mey worked at the Tegel Military Experimental Station and then at the General Electricity Company (AEG), where he specialized in the improvement of incandescent lamps. In 1909 he became the head of the AEG bulb factory. During the First World War, Mey served in the infantry on the Western Front from 1914 to 1917. After the war, Mey resumed his employment at AEG and, following the spin-off of the light bulb production of AEG, Deutsche Gasglühlicht AG (Auergesellschaft) and 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.

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

Brief description: The transfer of the AEG Telefunken Archive from Frankfurt a. M. to the care of the German Museum of Technology in Berlin began in 1996. The large volume of material (the first delivery alone consisted of more than 250 Euro pallets) made it necessary to divide this total stock into individual sub-stocks. The basis for this division was the diversity of the respective archives, which include files, company fonts, photographs, etc.. The following is a list of the individual available partial collections (whereby the inventory abbreviation "I.2.060" always represents the AEG Telefunken archive): A - AEG file collection, term (1854) 1883 to 1951, ;
