While educating international students is celebrated as a means of promoting mutual understanding among nations, American higher education has always been entangled with geopolitics. This essay focuses on Tang Tsou, the Chinese scholar who came to the United States as a student in 1941, eventually becoming the nation's leading China expert and producing knowledge about China for the United States during the Cold War. It analyzes how Tsou navigated a complex political terrain in which his Chinese identity was both a professional asset and a liability. Examining Tsou's personal and professional decisions as well as his response to the politicization of his Chinese identity reveals the (geo)politicization of higher education more broadly.
