Abstract Francis Heisler practiced law, representing numerous labor unions, conscientious objectors and draft resisters, and handled many civil rights and civil liberties cases in both Chicago, IL and California. His papers reflect his legal career with primary emphasis on labor-related cases.

Abstract This collection of correspondence, press releases, newspaper clippings, speeches, trial briefs and transcripts, and published pamphlets and leaflets, thoroughly documents the Worker's Defense League's efforts to obtain justice for labor organizers, government critics, victims of racial and economic discrimination, and conscientious objectors, through established, legal processes.
