Chen Jingrun (simplified Chinese: 陈景润; traditional Chinese: 陳景潤; pinyin: Chén Jǐngrùn; Wade–Giles: Ch'en Ching-jun; Foochow Romanized: Dìng Gīng-ê̤ṳng, May 22, 1933 – March 19, 1996) was a Chinese mathematician who made significant contributions to number theory.
Chen was the third son in a large family from Fuzhou, Fujian, China. His father was a postal worker. Chen Jingrun graduated from the Mathematics Department of Xiamen University in 1953. His advisor at Chinese Academy of Sciences was Hua Luogeng.
His work on the twin prime conjecture, Waring's problem, Goldbach's conjecture and Legendre's conjecture led to progress in analytic number theory. In a 1966 paper he proved what is now called Chen's theorem: every sufficiently large even number can be written as the sum of a prime and a semiprime (the product of two primes) — e.g., 100 = 23 + 7·11.
