This collection consists primarily of official, legal and financial documents that were collected to secure restitution for the estate of the Cohn family that ran hosiery factories in Saxony (Görlitz and Meerane).

This family collection primarily focuses on the immigration of Werner and Vera Gamby from Hamburg to New York. In addition, it documents the immigration of Vera Gamby's parents and the attempted immigration and later deportation of Werner's mother, aunt, and other family members. The collection also contains documentation and research on family genealogy and photographs of family members. The collection includes correspondence, photographs and photo albums, official documents, family trees, and unpublished manuscripts by family members.

The Werner Cohn Collection contains papers of members of the Cohn and related families.

The collection encompasses personal correspondence and papers, including official documents of family members, photographs, notes and notebooks, and a few newspaper clippings and other articles. About half the collection consists of restitution correspondence and documentation.
