Li Dazhao
Chen Duxiu (; October 8, 1879 – May 27, 1942) was a Chinese revolutionary socialist, educator, philosopher and author, who co-founded the Communist Party of China (with Li Dazhao) in 1921. From 1921 to 1927, he served as the Communist Party's first General Secretary. Chen was a leading figure in both the Xinhai Revolution that overthrew the Qing dynasty and the May Fourth Movement for scientific and democratic developments in the early Republic of China. After his expulsion from the Communist Party in 1929, Chen was for a time the leader of China's Trotskyist movement.
