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.

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.

McDonald, directed and authored major studies in the fields of Jewish community centers and education.

In 1942, Waldman was promoted to executive vice-president, a position he held until his retirement in 1945.

The Baron de Hirsch Fund Records document the organization's involvement in the planning of agricultural communities across the United States and to some extent in South America; the founding and administrative dealings of agricultural and trade schools; the establishment of the Jewish Agricultural Society; and the business records of the Fund itself.

In this respect, the collection is of major interest for Jewish genealogists as it documents a number of individual immigrants. In addition, the collection contains documentation on the administration and organization of the fund, documentation on Jewish farming colonies such as the Jewish Agricultural Society, Woodbine Colony and Agricultural School, and documentation on the Baron de Hirsch Trade School. In addition, the collection contains blueprints and photographs of facilities.
