Hirschbruch Family Collection

Identifier: AR 25720

Scope and Content Note

This collection is primarily the result of an intensive family research of Josef Hadar (né Hirschbruch), the son of Ludwig and Elsa Hirschbruch, about the Hirschbruch family. It contains several letters between him and a professional genealogist and between him and friends and family members helping him to extend the family tree. He also collected different articles related to his family. Besides microfilm records, which were used for the genealogy, it also includes family trees of, for example, the Hirschbruch family and the Pulvermacher family.

The second part of this collection deals with the parents of Josef Hirschbruch: Elsa Graetz and Ludwig Hirschbruch. It consists of diaries, notebooks, a family register, and poetry books.
