Harvard Department of Social Relations—the same department founded by Talcott Parsons and still heavily influenced by the structural-functionalist paradigm of Parsons. As White previously only taught graduate courses at Carnegie and Chicago, his first undergraduate course was An Introduction to Social Relations (see Influence) at Harvard, which became infamous among network analysts. As he "thought existing textbooks were grotesquely unscientific," the syllabus of the class was noted for including few readings by sociologists, and comparatively more readings by anthropologists, social psychologists, and historians. White was also a vocal critic of what he called the "attributes and attitudes" approach of Parsonsian sociology, and came to be the leader of what has been variously known as the “Harvard Revolution," the "Harvard breakthrough," or the "Harvard renaissance" in social networks. He worked closely with small group researchers George C. Homans and Robert F. Bales, which was largely compatible with his prior work in organizational research and his efforts to formalize network analysis. Overlapping White's early years, Charles Tilly, a graduate of the Harvard Department of Social Relations, was a visiting professor at Harvard and attended some of White's lectures - network thinking heavily influenced Tilly's work. White remained at Harvard until 1986. In addition to a divorce from his wife, Cynthia, (with whom he published several works) and wanting a change, the sociology department at the University of Arizona offer him the position as department chair. He remained at Arizona for two years. Columbia University In 1988, White joined Columbia University as a professor of sociology and was the director of the Paul F. Lazarsfeld Center for the Social Sciences. This was at the early stages of what is perhaps the second major revolution in network analysis, the so-called "New York School of relational sociology." This invisible college included Columbia as well as the New School for Social Research and New York University. While the Harvard Revolution involved substantial advances in methods for measuring and modeling social structure, the New York School involved the merging of cultural sociology with network-structural sociology, two traditions which had previously been antagonistic. White stood at the heart of this, and his magnum opus Identity and Control was a testament to this new relational sociology. In 1992, White received the named position of Giddings Professor of Sociology and was the chair of the department of sociology for various years until his retirement. He now resides in Tucson, Arizona.
