Robert T. Oliver was a towering figure in rhetoric and communication, a pioneer in Asiacentric approach to intercultural communication, and an important figure in the early development of Korea in the 40’s and 50’s. This essay focuses on four major intercultural contributions of Professor Oliver’s research – all prescient at the time and highly influential in the evolution of the field: (1) Critiquing the Eurocentric bias of rhetoric/communication, (2) offering an Asiacentric alternative to the study of rhetoric/communication, (3) utilizing an intraculural perspective to frame rhetoric/communication research, and (4) envisioning international diplomacy as a site for examining rhetoric/ communication.
