Anselm Franz

Dr. Anselm Franz (January 21, 1900—November 18, 1994) was a pioneering Austrian jet engine engineer known for the development of the Jumo 004, the world's first mass-produced turbojet engine by Nazi Germany during World War II, and his work on turboshaft designs in the U.S. after the war as part of Operation Paperclip, including the T53, the world's first helicopter turboshaft engine, the T55, the AGT-1500, and the PLFIA-2, the world's first high-bypass turbofan engine.

Born in Schladming, Austria, on January 21, 1900, Franz studied mechanical engineering at the Graz University of Technology and earned a doctoral degree from the Humboldt University of Berlin. Franz worked as a design engineer at a company in Berlin, where he developed hydraulic torque converters.

In 1936, he joined Junkers, and during much of the 1930s he was in charge of supercharger and turbocharger development.

Meanwhile, Hans von Ohain's first jet engines were being run at Heinkel, although there was little official interest. Helmut Schelp and Hans Mauch, at the Reichsluftfahrtministerium (RLM), tried to keep development moving through the "back door", attempting to interest existing engine companies in jet development. On one such visit in early 1939 Otto Mader at Junkers said that even if the idea was worth looking at, he had no one to run such an effort. Schelp suggested that Franz would be perfect for the job, given his experience in turbocompressor work.
