and 1970s during the Harvard Revolution, as well as the 1980s and 1990s at Columbia during the New York School of relational sociology. White's student and teaching assistant, Michael Schwartz, took notes in the spring of 1965, known as Notes on the Constituents of Social Structure, of White's undergraduate Introduction to Social Relations course (Soc Rel 10). These notes were circulated among network analysis students and aficionados, until finally published in 2008 in Sociologica. As popular social science blog Orgtheory.net explains, "in contemporary American sociology, there are no set of student-taken notes that have had as much underground influence as those from Harrison White’s introductory Soc Rel 10 seminar at Harvard." The first generation of Harvard graduate students that trained with White during the 1960s went on to be a formidable cohort of network analytically inclined sociologists. His first graduate student at Harvard was Edward Laumann who went onto develop one of the most widely used methods of studying personal networks known as ego-network surveys (developed with one of Laumann's students at the University of Chicago, Ronald Burt). Several of them went on to contribute to the "Toronto school" of structural analysis. Barry Wellman, for instance, contributed heavily to the cross fertilization of network analysis and community studies, later contributing to the earliest studies of online communities. Another of White's earliest students at Harvard was Nancy Lee (now Nancy Howell) who used social network analysis in her groundbreaking study of how women seeking an abortion found willing doctors before Roe v. Wade. She found that women found doctors through links of friends and acquaintances and was four degrees separated from the doctor on average. White also trained later additions to the Toronto school, Harriet Friedmann ('77) and Bonnie Erickson ('73). One of White's most well-known graduate students was Mark Granovetter, who attended Harvard as a phd student from 1965 to 1970. Granovetter studied how people got jobs, discovered they were more likely to get them through acquaintances than through friends. Recounting the development of his widely cited 1973 article, The Strength of Weak Ties, Granovetter credits White's lectures and specifically White's description of sociometric work by Anatol Rapaport and William Horrath that gave him the idea. This, tied with earlier work by Stanley Milgram (who was also in the Harvard Department of Social Relations 1963–1967, though not one of White's students), gave scientists a better sense of how the social
