Qian Xuesen

Chinese rocket scientist (1911–2009)

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.
