Zhou Tongqing
Zhou Tongqing (Chinese: 周同庆; 21 December 1907 – 13 February 1989), also known as Tung-Ching Chow, was a Chinese optical physicist. After earning his Ph.D. from Princeton University, he taught at Peking University, National Central University, Shanghai Jiao Tong University, and Fudan University. He led the development of China's first X-ray tube in 1953 and was elected a founding member of the Chinese Academy of Sciences in 1955. His research was disrupted when he was subject to severe persecution during the Anti-Rightist Campaign and the Cultural Revolution. Although later politically rehabilitated, he was plagued by poor health for the rest of his life.
