Seymour Martin Lipset was an American sociologist and political scientist. His major work was in the fields of political sociology, trade union organization, social stratification, public opinion, and the sociology of intellectual life. He also wrote extensively about the conditions for democracy in comparative perspective. He was president of both the American Political Science Association (1979–1980) and the American Sociological Association (1992–1993). A socialist in his early life, Lipset later moved to the right, and was considered to be one of the first neoconservatives.
