1932 near Göttingen

Chiungtze C. Tsen (Chinese: 曾炯之; pinyin: Zēng Jiǒngzhī; Wade–Giles: Tseng Chiung-chih, April 2, 1898 – October 1, 1940[1]) was a Chinese mathematician born in Nanchang, Jiangxi, who proved Tsen's theorem. He was one of Emmy Noether's students at the University of Göttingen. He returned to China in 1935. After the full-scale Japanese invasion of China in 1937, he fled and eventually settled in Xikang, where he became a professor at the newly-founded National Xikang Institute of Technology. He died of a stomach ulcer in Xichang, Xikang on October 1, 1940, and a memorial service was held on November 18, 1940.[2] (Many Chinese sources mistakenly give his date of death as November 1940.)

Zeng's death reported by the journal Xin Ningyuan Yuekang, Vol. 1, No. 3.

One of his research interests was quasi-algebraic closure. In that area he proved the theorem that took his name (Tsen's theorem).
