Ernst Pincus Collection

Identifier: AR 25873

Scope and Contents

The Ernst Pincus Collection largely comprises papers and correspondence of Ernst and his wife Käte Pincus, along with some papers of the larger extended family. It also includes several folders of family trees.

The focus of this collection is on Ernst Pincus and his wife Käte (also spelled Käthe, née Zorek), whose papers are located in Series I. Their personal papers and correspondence form over half of the collection's first series, with one folder of correspondence sent to them. Although there are a few letters sent prior to the 1930s, the bulk of the correspondence is letters sent to them, primarily from their parents, during the 1930s and 1940s after Ernst and Käte were already living in the United States. Their papers largely focus on their education and Ernst's early professional work as a lawyer; such papers include many school documents of Käte's, university documents of Ernst, and official notifications from the court in Berlin regarding potential positions for Ernst there.

Series I additionally holds papers and a small amount of correspondence of other family members. The family papers include school writing of Theodor Pincus, as well as documents relating to his death. In addition, the series contains some photographs of family members.

Series II contains a number of family trees, with a focus on the Pincus and Silberstein branches of the family. One tree pertains to the Zorek branch of the family.
