Chen-Ning Franklin Yang, also known as Yang Zhenning (simplified Chinese: 杨振宁; traditional Chinese: 楊振寧; pinyin: Yáng Zhènníng; born October 1, 1922), is a Chinese physicist who works on statistical mechanics and particle physics. He and Tsung-dao Lee received the 1957 Nobel Prize in Physics for their work on parity nonconservation of weak interaction. The two proved theoretically that one of the basic quantum-mechanics laws, the conservation of parity, is violated in the so-called weak nuclear reactions, those nuclear processes that result in the emission of beta or alpha particles.

Yang was born in Hefei, Anhui, China; his father, Yang Wu-Chih (楊武之) (1896–1973), was a mathematician, and his mother, Luo Meng-hua (羅孟華), was a housewife. Yang attended elementary school and high school in Beijing, and in the autumn of 1937 his family moved to Hefei after the Japanese invaded China. In 1938 they moved to Kunming, Yunnan, where the National Southwestern Associated University, Lianda, was located. In the same year, as a second year student, Yang passed the entrance examination and studied at Lianda. He received his bachelor's degree in 1942, with his thesis on the application of group theory to molecular spectra, under the supervision of Ta-You Wu. He continued to study graduate courses there for two years under the supervision of Wang Zhuxi, working on statistical mechanics. In 1944 he received his master's degree from Tsinghua University, which had moved to Kunming during the Sino-Japanese War (1937-1945). Yang was then awarded a scholarship from the Boxer Indemnity Scholarship Program, set up by the United States government using part of the money China had been forced to pay following the Boxer Rebellion. His departure for the United States was delayed for one year, during which time he taught in a middle school as a teacher and studied field theory.
