Chen Duxiu (1879-1942), is without question one of the most significant figures in modern Chinese history. Yet his early life has been curiously neglected in Western scholarship. In this dissertation I examine the political, social and intellectual networks that played such an important role in his early career---a career that witnessed his transformation from a classical scholar in the Qing dynasty (1644-1912), to a reformer, to a revolutionary, to a renowned writer and editor, to a university dean, to a founder of the Chinese Communist Party, all in the space of about two decades.
