This collection documents the Prölsdorfer and Lederman families. A narrative summary of the materials by the donor is found in folder 1.

Prölsdorfer family materials include modern reproductions of family photographs from the 1930s; Irma Proll's naturalization certificate; color photocopies of the inscription in a 1919 prayer book; the cover of a military passbook; photocopies of family documents such as passports, photos, and correspondence, primarily about the 1933 preventive detention of Ignaz Prösldorfer, Hermann Krämer, and Fritz Krämer (some with handwritten English translations); and a genealogy of the Krämer, Fleischmann, and Wilmersdörfer families.

Documents relating to Fred Lederman include birth, naturalization, and marriage certificates, photographs from the 1920s through the 1950s, a Mosbacher family genealogy, and other family history documents. Lederman's military documents include identification cards, separation letters, his letter of commendation for his Bronze Star, a photograph and a sketch of him in uniform, and other military records from his service in the United States Army. A large photograph of his unit, Company A, 56th Signal Battalion at Fort Jackson, South Carolina, is found in the oversize folder.

The Roth family folder contains a genealogy originally written in Hungarian in 1953 by Hermin Roth Iszak, and translated into English in 1988 by her daughter Madeleine Stern.

Biographical Note

Ignaz Prölsdorfer (later Jack Proll, 1895-1974), his wife Irma née Kramer (1904-2007), and his son Gert (George, 1931- ) left Gerolzhofen, Germany for the United States in 1936. After her husband died, Irma Proll married Fred Lederman (born Manfred Ledermann, 1918-2003). Lederman was a baker by trade. After he fled Neckarsteinach, Germany for the United States, he was drafted into the Army and returned to Europe in 1944, where he earned a Bronze Star in France for convincing a German unit to surrender. He married Frida née Eben in 1954. George Proll married Rita Rado (1932- ).
