The second part of the collection focuses more strongly on Henry Bauer and his life, elucidating the time he spent in Germany as well as the time after his immigration to the United States.

This collection contains the records of the National Refugee Service (NRS), a refugee aid organization founded in New York City in 1939 to assist refugees fleeing Nazi persecution. A successor agency to the National Coordinating Committee for Aid to Refugees and Emigrants Coming from Germany, which had operated as an umbrella organization of refugee aid agencies since 1934, the NRS remained in existence until 1946, when it was merged into the new organization United Service for New Americans. The NRS program encompassed a migration service that assisted with affidavits, visas and other legal aspects of the immigration process; temporary relief and casework services; job placement, retraining, and small business loans; help in resettling to localities throughout the country; and social and cultural adjustment to American life. The records include minutes, correspondence, memoranda, and reports related to the board of directors; the executive director; lay advisory committees; the various departments within the NRS; special committees assisting professional groups, including physicians, musicians, rabbis, social workers, and scholars; and cooperating refugee-assistance committees and organizations across the United States.

Founded in 1969, the American Association for Ethiopian Jews (AAEJ) was instrumental in the international effort to promote recognition of the Beta Israel (known among non-Jewish Ethiopians as "Falashas") by Israeli authorities, and to assist Jewish emigration from Ethiopia to Israel. The extensive files of the AAEJ include case work files, research materials and Jewish artifacts collected in Ethiopia by AAEJ workers. In the wake of the successful evacuation of Ethiopian Jewry to Israel in 1993, the AAEJ decided to disband and voted to deposit its records at the American Jewish Historical Society. Included are correspondence, office files, photographs, slides, videotapes, audiocassettes and other materials which pertain to AAEJ's efforts to raise the consciousness of the American Jewish community about this unique Jewish subculture. The organization's papers supplement those of its founder, Graenum Berger, which are also held at the American Jewish Historical Society.

Included in the collection are the administrative records of the Foundation (minutes, financial records, bylaws), publications produced by the Foundation including manuscript submissions for the influential publication The Reconstructionist, correspondence, sermons, prayer books produced by the Foundation, syllabi, sheet music, photographs, and speeches, among other material. In the correspondence are letters from Martin Buber, J. Edgar Hoover, and Albert Schweitzer.
