Lucien Wolf (1857-1930) was a diplomat, foreign affairs expert, journalist, and historian. As the secretary of the Joint Foreign Committee of the Board of Deputies of British Jews and the Anglo-Jewish Association (earlier the Conjoint Foreign Committee), Lucien Wolf took a leading role in the efforts of Western Jewry to aid persecuted Jews in Eastern Europe. He was also a delegate to the Paris Peace Conference (1919), where he helped to draft the minorities treaties guaranteeing the rights of Jews and other ethnic and religious minority groups. David Mowshowitch (1887-1957) was Lucien Wolf's secretary and aide at the Joint Foreign Committee for many years and continued to work for the Joint Foreign Committee until the 1950s. The collection consists of the papers of Lucien Wolf and David Mowshowitch, as well as fragmentary records of the Joint Foreign Committee. The material includes personal papers, correspondence, reports, memoranda, minutes of meetings, copies of articles, and press clippings. The documents pertain to the situation of persecuted Jews throughout the world, most notably the efforts of the Joint Foreign Committee of the Board of Deputies of British Jews and the Anglo-Jewish Association to aid the Jews of Eastern Europe, and to the Peace Conference at Paris in 1919 and the minorities treaties. There is also material on Lucien Wolf's and David Mowshowitch's other activities, most importantly Lucien Wolf's career as a journalist and as a historian of the Jewish community in Britain.

The collection documents the National Jewish Welfare Board's (JWB) evolution from an organization founded in 1917 to provide support for soldiers in times of war to an agency involved in all aspects of Jewish life both in the United States and abroad. In 1990 JWB recreated itself as the Jewish Community Centers Association of North America.

University professor, historian, and scholar Oscar I. Janowsky sought to understand Jewish culture and human rights in light of modern anti-Semitism, imperialism, and pluralistic states. Throughout his robust career he was a professor of history at the City College of New York, he also served as an advisor to League of Nations High Commissioner James G. McDonald, directed and authored major studies in the fields of Jewish community centers and education. The papers in this collection include his correspondence with colleagues and friends, research notes and article drafts, and his unpublished memoirs.

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. In 1942, Waldman was promoted to executive vice-president, a position he held until his retirement in 1945. The Morris Waldman Files relate to all of Waldman's activities as acting executive secretary and vice-president of the AJC.
