Abstract: Papers of Staughton Lynd, a leftist historian and labor lawyer who was prominent in both the civil rights and the anti-war movements. The majority of the papers cover the mid-1960s to the early 1970s, with the emphasis on the varied social movements and radical activities with which he was affiliated rather than on Lynd himself. Articles and writings, correspondence, and clippings and other printed matter refer to campus protests of the 1960s; civil rights; the Vietnam War; tax reform; the Kennedy assassination; Jobs or Income Now (JOIN), a group which sought to organize the poor in Chicago; union organizing, especially among public employees in the Chicago and Gary, Indiana, area; the Mass Party Organizing Committee, a group which attempted to formulate a mass, Leninist, working-class party; and the New American Movement, a group which sought to build a mass-based democratic socialist movement in the United States. There are also files on Lynd's attempt to bring a leftist perspective to the historical profession and to the American Historical Association.
