Lewis A. Coser papers document the personal, political, and professional endeavors of a German-American sociologist. The bulk of the collection is correspondence, but course materials, documents, manuscripts, newspaper clippings, periodicals, photographs, and publishing files are also included. Some family letters, photographs, and manuscripts, as well as the French Resistance publications, predate his immigration to the United States in 1941, while the remainder of the collection chronicles his scholarly career as a professor and author. Coser’s community involvement in a Quaker organization known as the American Friends Service Committee (AFSC) and his role as founding editor of Dissent magazine are also covered.
