Qian Xuesen

Early Life and Study in the United States

Qian Xuesen, whose ancestral home was Hangzhou, Zhejiang, was born in Shanghai on 11 December 1911. He studied mechanical engineering at Shanghai Jiao Tong University from 1929 to 1934, won a Tsinghua government scholarship for study in the United States in 1934, and went to America in 1935, studying aeronautical engineering at MIT before moving to the California Institute of Technology, where he received his PhD in aeronautics in 1939. He stayed on to work on aerodynamics and jet propulsion; according to a 2009 People's Daily Overseas Edition article, around the end of the Second World War he accompanied a US Air Force advisory group to Germany to examine its missile technology and was given the rank of colonel. In the late 1940s he returned to China to marry the singer Jiang Ying. By 1950 he was Caltech's Robert H. Goddard Professor of Jet Propulsion.

1950–1955: Held in the United States

In 1950 Qian's security clearance was revoked. According to Chinese official media, when he prepared to return home with his family, US customs seized his luggage and the immigration service told him he could not leave; that September the FBI detained him on Terminal Island, and after release he remained under surveillance. Chinese media widely quote a US Navy under-secretary as saying Qian was "worth five divisions wherever he is". His Caltech colleague Frank Marble recalled in a 1997 oral history for the Caltech Archives that Qian was accused of having joined the Communist Party and of failing to declare it when re-entering the country after marrying in China in 1946; the Immigration and Naturalization Service held a hearing and issued a deportation order to be carried out five years later, during which he was to lose contact with classified work. Many people with security clearances avoided him, and his landlady asked the family to move. In this period Qian turned to engineering cybernetics, publishing "Engineering Cybernetics" in English in the United States in 1954.

In June 1955 Qian hid a letter to Chen Shutong, vice-chairman of the NPC Standing Committee, inside a family letter to relatives in Belgium, asking for help to return and saying that "the Americans are lying again, claiming that all Chinese students who wish to return have been released". The letter reached Zhou Enlai. The Sino-US ambassadorial talks opened in Geneva on 1 August, and according to Chinese accounts the Chinese representative cited the letter in demanding that Qian and others be allowed to leave. On 17 September Qian's family sailed from the United States aboard the SS President Cleveland, reaching China on 8 October.

Leading Missile and Space Development

When the Chinese Academy of Sciences' Institute of Mechanics was founded in January 1956, Qian became its first director; in April he was appointed to the Aviation Industry Commission chaired by Nie Rongzhen. On 18 February 1957 Zhou Enlai signed the order appointing him first president of the Fifth Academy of the Ministry of National Defence. In 1958 the Academy of Sciences set up a satellite planning group (code-named "581") with Qian as head. China's first domestically built short-range missile was successfully test-flown in November 1960. On 8 January 1965 Qian formally proposed a national satellite research plan, and that year he became Vice-Minister of the Seventh Ministry of Machine Building. On 27 October 1966 he assisted Nie Rongzhen in directing the "two bombs combined" test at Jiuquan, in which a medium-range missile carried an atomic warhead. During the Cultural Revolution he was assigned in 1967 to rebuild the satellite team and in 1968 became president of the newly founded China Academy of Space Technology, which developed Dongfanghong-1, launched on 24 April 1970.

The 1958 Crop-Yield Article

During the Great Leap Forward, Qian published "How High Can Grain Yields Per Mu Go?" in China Youth Daily on 16 June 1958, calculating from the utilisation of solar energy that rice and wheat yields could reach "more than 20 times" the then figure of over 2,000 jin per mu; he had expressed similar views in People's Daily on 29 April. Qian Jiang, a former People's Daily editor, wrote in a retrospective on the "satellite" yield reports that the scientist "enjoyed very high prestige, and his judgement led many people, including the leader, to believe it".

Later Life and Assessments

Qian was vice-chairman of the China Association for Science and Technology from 1970 to 1982 and later its honorary chairman, and was a vice-chairman of the 6th, 7th and 8th National Committees of the CPPCC. On 16 October 1991 the State Council and Central Military Commission named him a "State Scientist of Outstanding Contribution" with a First-Class Hero Model medal, and on 18 September 1999 he received the "Two Bombs, One Satellite" Meritorious Medal. He died in Beijing on 31 October 2009, aged 98.

Chinese official accounts have long called him the founder of China's missile and space programmes. Historians Alexander Geppert and Lu Liu, writing in the British Journal for the History of Science in 2025, examine how he was transformed from an engineer known only within expert circles into China's public "face of space", a process they see as especially marked after the 1989 Tiananmen crackdown, arguing that the resulting persona became largely an "empty signifier".
