Qian Xuesen ( 錢學森) (11 December 1911 – 31 October 2009) was a scientist who made important contributions to the missile and space programs of both the United States of America and People's Republic of China. Historical documents in the U. S. commonly refer to him with the earlier family-name last spelling, Hsue-Shen Tsien or H.S. Tsien.
During the 1940s Qian was one of the founders of the Jet Propulsion Laboratory at the California Institute of Technology. During the Red Scare in the 50s, he was accused of being a communist, and he was stripped of his security clearance. Qian then decided to return to China and after waiting 5 years Qian was released in 1955, in exchange for the repatriation of American pilots captured during the Korean War. He returned to lead the Chinese rocket program, and became known as the "Father of Chinese Rocketry" (or "King of Rocketry").
During the China Crises Qian chose to stay in China when many other scientist were secretly leaving, this was due to his anger at the United States and despite personal appeals from former friends at the JPL. Qian was pressed by the Chinese government to continue work with rockets and in 1987 help modify a Soviet re-useable craft. This effort would help the PRC join the Space Race.
In 2008, China Central Television named Qian as one of the most inspiring people in China. He died at the age of 97 on October 31, 2009 in Beijing.
