After the war, Wagner was the first of many German scientists brought to America as part of
Operation Paperclip, arriving at Frederick, Maryland on 18 May 1945 with seven large cases of blueprints and other technical data. Wagner and his team were moved to the Special Devices Center, a U.S.-Navy run research unit housed at the Castle Gould and Hempstead House, the former estate of
Daniel and Florence Guggenheim at Sands Point, Long Island. There he supported U.S. efforts to deploy glide bombs against Japan. Wagner then moved to the new
Naval Air Missile Test Center in Point Mugu, California, the centerpiece of the U.S. Navy's research into guided missiles. There he helped develop the control mechanisms for advanced missiles, several of which remain (in upgraded forms) in service today. A formerly classified FBI counterintelligence report describes his approach to his work: An excellent German scientist of good character and who is not interested in politics... He has given no evidence of being either pro-Nazi or pro-Communist and is disinterested politically... Once belonged to the German SS for a four week’s instruction course but dropped out of same on his own volition... Is an opportunist who is interested only in science and does not subscribe to any political ideology... Since the death of his wife, Wagner has been drinking considerably but is not a drunkard. Wagner left US government service and formed his own technical consulting firm, HA Wagner Company. He sold this company to
Curtiss-Wright in 1957 and returned to Germany to take up a position as professor of Technical Mechanics and Space Technology at the
RWTH Aachen University. He continued to serve as technical advisor to several U.S. defense companies during this period. Wagner was awarded the
Ludwig-Prandtl-Ring from the
Deutsche Gesellschaft für Luft- und Raumfahrt (German Society for Aeronautics and Astronautics) for "outstanding contribution in the field of aerospace engineering" in 1980. He died aged 82 on 28 May 1982 in
Newport Beach, California. ==See also==
