Qian Xuesen: The man the US deported – who then helped China into space

A Chinese scientist, Qian Xuesen, helped two superpowers reach the moon, writes Kavita Puri, but his story is remembered in only one of them.

In Shanghai there is an entire museum containing 70,000 artefacts dedicated to Qian, “the people’s scientist”.

However, in the US, where he studied and worked for more than a decade, his significant contributions to space exploration are rarely remembered at all.

Qian was a Chinese citizen, but the Republic of China was an ally of the US, so there was “no massive suspicion about a Chinese scientist at the heart of American space endeavour”, says Fraser Macdonald.

Qian was given security clearance to work on classified weapons research, and even served on the US government’s Science Advisory Board.By the end of the war he was one of the world’s foremost experts on jet propulsion, and was sent with Theodore von Karman on an extraordinary mission to Germany, holding the temporary rank of lieutenant colonel. Their goal was to interview Nazi engineers, including Wernher von Braun, Germany’s leading rocket scientist; America wanted to find out exactly what the Germans knew.

But by the end of the decade Qian’s glittering career in the US came to a sudden halt, and his life there began to unravel.
