Erving Goffman

From Wikipedia:

Erving Goffman, a Canadian-born sociologist and writer, was considered "the most influential American sociologist of the twentieth century". In 2007 he was listed by The Times Higher Education Guide as the sixth most-cited author in the humanities and social sciences, behind Anthony Giddens and ahead of Jürgen Habermas.

Goffman was the 73rd president of the American Sociological Association. His best-known contribution to social theory is his study of symbolic interaction. This took the form of dramaturgical analysis, beginning with his 1959 book, The Presentation of Self in Everyday Life. Goffman's other major works include Asylums (1961), Stigma (1963), Interaction Ritual (1967), Frame Analysis (1974), and Forms of Talk (1981). His major areas of study included the sociology of everyday life, social interaction, the social construction of self, social organization (framing) of experience, and particular elements of social life such as total institutions and stigmas.
