Harrison White

White trained sociologists to study patterned relationships rather than treating individuals as isolated units. His students and collaborators at Harvard helped turn network analysis into a major sociological research program during the 1960s and 1970s.

Identity and Control argues that social identities emerge through attempts to manage uncertain relationships and networks. First published in 1992, it links network structure with culture, stories, and social action.

White described markets as social structures in which producers watch one another and occupy differentiated niches. His 1981 article "Where Do Markets Come From?" challenged models that explain markets only through anonymous exchanges between buyers and sellers.

White influenced a generation of network scholars that included Mark Granovetter and Barry Wellman. Granovetter's work on weak ties became one of the most widely recognized results associated with the network tradition White helped build.
