Qian Xuesen
Qian Xuesen (Chinese: 钱学森; 11 December 1911 – 31 October 2009; also spelled as Tsien Hsue-shen) was a Chinese aerospace engineer and cyberneticist who made significant contributions to the field of aerodynamics and established engineering cybernetics. He achieved recognition as one of America's leading experts in rockets and high-speed flight theory prior to his returning to China in 1955. Qian received his undergraduate education in mechanical engineering at National Chiao Tung University in Shanghai in 1934. He travelled to the United States in 1935 and attained a master's degree in aeronautical engineering at the Massachusetts Institute of Technology in 1936. Afterward, he joined Theodore von Kármán's group at the California Institute of Technology in 1936, received a doctorate in aeronautics and mathematics there in 1939, and became an associate professor at Caltech in 1943.
