III. Jacob Potofsky correspondence, 1913-1929.

Much of the correspondence deals with the ACWA's organizing efforts throughout the United States and Canada and Potofsky's role in coordinating these organizing drives. There is also a good deal of information about the ACWA's sensitivity to ethnic issues within the union. Much attention is devoted to conflicts between and among Jewish, Italian, Polish and other workers. There is also documentation of the political conflicts which often threatened union solidarity.

Individuals represented in the collection include: August Bellanca; Dorothy Jacobs Bellanca; Clarence Darrow; Bessie Hillman; Sidney Hillman; Fiorello LaGuardia; Frank Rosenblum; Joseph Schlossberg; and B.C. Vladek.

Major organizations represented include local unions and joint boards of the ACWA; Hart, Schaffner, and Marx; the periodicals Jewish Daily Forward and the Nation; the Women's Bureau of the U.S. Dept. of Labor; and the Women's Trade Union League. Topics covered include union organizing in the U.S. and Canada, ethnic relations within the ACWA, and politics and the union in the U.S.
