Foreword: * May 22, 1926 in Berlin † September 29, 2006 in Princeton Peter M. Grosz was born in Berlin as the son of the famous painter George Grosz. After his parents emigrated to the USA in 1932, he lived for another year with his aunt at Belle Alliance Strasse 1, where he had a good view of the flight operations at Tempelhof Airport from the fifth floor. These impressions fascinated him to such an extent that his childlike enthusiasm for aircraft turned into a lifelong hobby. In 1933 he moved to his parents in New York. He studied physics at Harvard and in 1952 moved with his wife Lilian to Princeton, which became their new home. There he worked in various research laboratories and several companies. After the death of his father in 1959, Peter Grosz administered and processed his estate. His hobby, however, remained aviation and with more than 220 published technical-historical articles, including standard works such as "The German Giants", "Austro-Hungarian Aircraft of World War I", "Die Fokker-Flugzeugwerke in Deutschland 1912-1921", he was the internationally recognized expert in the field of German aviation development up to the end of the First World War. Peter M. Grosz's well-organised, systematically structured archive of technical history comprises around 30,000 photographs, 160 Leitz files with technical documents, 104 manuals and operating instructions, more than 1500 books and over 220 publications published since the mid-1950s. The folders were dissolved during the new distortion, whereby the existing order structure was largely retained. In addition to the technical-historical documents on the individual aircraft manufacturers, the documents on the establishment of the German aviation troops during the First World War and Peter M. Grosz's extensive correspondence with other aviation historians are also of importance. The manuals and operating instructions were transferred to the collection of company documents, and the books were handed over to the library. The extensive photo collection will be listed separately at a later date, but can already be used with restrictions. The estate was presented to the German Museum of Technology on 2 October 2007 by Lilian Grosz. It has a scope of 1139 units of registration with a duration of 1889-2006.
