Wu Wenjun

Along with Yuan Longping, he was awarded the State Preeminent Science and Technology Award by President Jiang Zemin in 2000, when this highest scientific and technological prize in China began to be awarded. He also received the TWAS Prize in 1990 and the Shaw Prize in 2006. He was the President of the Chinese society of mathematics. He died on May 7, 2017, 5 days before his 98th birthday.

In 1957, he was elected as an academician of the Chinese Academy of Sciences. In 1986 he was an Invited Speaker of the ICM in Berkeley. In 1990, he was elected as an academician of The World Academy of Sciences (TWAS).

In 1947, he went to France for further study at the University of Strasbourg. In 1949, he received his PhD, for his thesis Sur les classes caractéristiques des structures fibrées sphériques, written under the direction of Charles Ehresmann. Afterwards, he did some work in Paris with René Thom and discovered the Wu class and Wu formula in algebraic topology. In 1951 he was appointed to a post at Peking University. However, Wu may have been among a wave of recalls of Chinese academics working in the West following Chiang Kai-shek's ouster from the mainland in 1949, according to eyewitness testimony by Marcel Berger, as he disappeared from France one day, without saying a word to anyone.

Wu's ancestral hometown was Jiashan, Zhejiang. He was born in Shanghai and graduated from Shanghai Jiao Tong University in 1940. In 1945, Wu taught several months at Hangchow University (later merged into Zhejiang University) in Hangzhou.
