The collection represents the papers of Morris David Waldman (1879-1963), a rabbi, social worker and communal leader, who was appointed executive secretary of one of the main Jewish defense organizations, the American Jewish Committee (AJC), in 1928. The executive secretary had top executive function at the organization and was in charge of working out and implementing the organization’s projects and policies regarding monitoring the civil and human rights of the Jews, and intervening on behalf of the Jews both in the U.S. and abroad.
