This is the history of the most significant translator, publisher, and distributor of left-wing literature in the United States. Based in Chicago and still publishing, Charles H. Kerr & Company began in 1886 as a publisher of Unitarian tracts. The company’s focus changed after its founder became a socialist at the turn of the century. Tracing Kerr’s political development and commitment to radical social change, “We Called Each Other Comrade” also tells the story of the difficulties of exercising the First Amendment in an often hostile business and political climate. A fascinating exploration in left-wing culture, this revealing chronicle of Charles H. Kerr and his revolutionary publishing company looks at the remarkable list of books, periodicals, and pamphlets that the firm produced and traces the strands of a rich tradition of dissent in America.
