Geismar family

The Hans David Blum Research Collection documents his research on the Jews of Breisach and his ancestors that culminated in a book entitled Juden in Breisach, that was published in 1998. The collection includes Hans David Blums’s research materials such as printed materials, documents (mostly copies), correspondence with archives and individuals, genealogical charts and tables, lists, and a large amount of notes.

This collection consists primarily of the research material underlying Werner Frank's genealogical work, "Legacy: the saga of a German-Jewish German family across time and circumstance" (2003, Avotaynu Foundation). It contains correspondence with distant relatives and genealogical researchers, copies of archival documents, and family trees relating to the following German-Jewish families from Baden: Frank, Regensburger, Heinsheimer, Oppenheimer, Furth, Wimpfheimer, Eppinger, Ottenheimer, Wolf (paternal) and Weingartner, Gutmann, Herz, Blum, Geismar, Auerbach, Auerbacher, Uffenheimer, Günzberger, Weil (maternal).
