(From Wikipedia) Qian Xuesen, (11 December 1911 – 31 October 2009), was a prominent Chinese aerodynamicist, cyberneticist and politician who contributed to rocket science and established engineering cybernetics. Recruited from MIT, he joined Theodore von Karman’s group at Caltech.[1] Later, he returned to China and made important contributions to China’s missile and space program.
During the Second Red Scare, in the 1950s, the US federal government accused him of communist sympathies. In 1950, despite protests by his colleagues, he was stripped of his security clearance.[2] He decided to return to China, but he was detained at Terminal Island, near Los Angeles.[3]
After spending five years under house arrest,[4] 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 China via Hong Kong.[5]
Upon his return, he helped lead the Chinese nuclear weapons program. This effort ultimately led to China’s first successful atomic bomb test and hydrogen bomb test, making China the fifth nuclear weapons state, and achieving the fastest fission-to-fusion development in history. Additionally, Qian’s work led to the development of the Dongfeng ballistic missile and the Chinese space program. For his contributions, he became known as the “Father of Chinese Rocketry”, nicknamed the “King of Rocketry”.[6][7]. He was known as one of the founding fathers of Two Bombs, One Satellite
