Von KГЎrmГЎn (center) during his work at the Jet Propulsion Laboratory in 1940ДЄpprehensive about developments in Europe regarding Nazism, in 1930 KГЎrmГЎn accepted the directorship of the Guggenheim Aeronautical Laboratory at the California Institute of Technology (GALCIT). KГЎrmГЎn left his post at RWTH Aachen in 1930. Subsequent conferences were organized as the International Union of Theoretical and Applied Mechanics. They organized the first international conference in mechanics held in September 1922 in Innsbruck. Josephine encouraged her brother Theodore to expand his science beyond national boundaries. KГЎrmГЎn engaged Wolfgang Klemperer to design a competitive glider. Some of his students took an interest in gliding and saw the competitions of the RhГ¶n-Rossitten Gesellschaft as an opportunity to advance in aeronautics. His time at RWTH Aachen was interrupted by service in the Austro-Hungarian Army from 1915 to 1918, when he designed the PetrГіczy-KГЎrmГЎn-ЕЅurovec, an early helicopter.ДЄfter the war he returned to Aachen with his mother and sister Josephine de Karman. In 1912 he accepted a position as director of the Aeronautical Institute at RWTH Aachen University, a leading German university. After graduating in 1902 he moved to the German Empire and joined Ludwig Prandtl at the University of GГ¶ttingen, where he received his doctorate in 1908. He studied engineering at the city's Royal Joseph Technical University, known today as Budapest University of Technology and Economics. One of his ancestors was Rabbi Judah Loew ben Bezalel. Theodore von KГЎrmГЎn was born into a Jewish family in Budapest, Austria-Hungary, as KГЎrmГЎn TГіdor, the son of Helen (Kohn, Hungarian: Kohn Ilka ) and MГіr KГЎrmГЎn. He is regarded as an outstanding aerodynamic theoretician of the 20th century. He was responsible for many key advances in aerodynamics, notably on supersonic and hypersonic airflow characterization.
