About Qian Xuesen
Qian Xuesen (Chinese: 钱学森; December 11, 1911 – October 31, 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 being deported to China in 1955. This occurred after having been accused of Communist sympathies — without evidence — during the Red Scare. Qian received his undergraduate education in mechanical engineering at National Chiao Tung University in Shanghai in 1934. He traveled 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. While at Caltech, he co-founded NASA's Jet Propulsion Laboratory. He was recruited by the United States Department of Defense and the Department of War to serve in various positions, including as an expert consultant with a rank of colonel in 1945. He became an associate professor at MIT in 1946, a full professor at MIT in 1947, and a full professor at Caltech in 1949. During the Second Red Scare in the 1950s, the United States federal government accused him of communist sympathies. In 1950, despite protests by his colleagues and without any evidence of the allegations, he was stripped of his security clearance. He was given a deferred deportation order by the Immigration and Naturalization Service, and for the following five years, he and his family were subjected to partial house arrest and government surveillance in an effort to gradually make his technical knowledge obsolete. After spending five years under house arrest, he was released in 1955 in exchange for the repatriation of American pilots who had been captured during the Korean War. He left the United States in September 1955 on the American President Lines passenger liner SS President Cleveland, arriving in mainland China via Hong Kong. Upon his return, he helped lead development of the Dongfeng ballistic missile and the Chinese space program. He also played a significant part in the construction and development of China's defense industry, higher education and research system, rocket force, and a key technology university. For his contributions, he became known as the "Father of Chinese Rocketry" and was nicknamed the "King of Rocketry". He is recognized as one of the founding fathers of Two Bombs, One Satellite. In 1957, Qian was elected an academician of the Chinese Academy of Sciences. He served as a Vice Chairman of the National Committee of the Chinese People's Political Consultative Conference from 1987 to 1998. He was the cousin of engineer Hsue-Chu Tsien, who was involved in the aerospace industries of both China and the United States. He is a cousin of the father of Roger Y. Tsien, the 2008 winner of the Nobel Prize in Chemistry.
