Käthe Klara Sitzmann (nickname “Klara”) is the mother of Peter Sitzmann and the sister of Irene Sitzmann, who are also listed in this memorial book. Käthe Klara Sitzmann was born in Unterriedenberg (situated in Bavaria) in 1919. Her father was the merchant Isidor Sitzmann; her mother was Betty Sitzmann née Hirschberg. Klara had two younger sisters, the one-year-younger Irene and the 1926-born Lidia. The father ran a manufactured goods shop in Unterriedenberg as well as a peddler's shop where also the mother worked. The family was well-to-do, lived in a six-bedroom apartment and could employ a domestic worker. Up to 1933, the family seemed to be well integrated in Unterriedenberg. But then the family was increasingly exposed to enmity. During the November pogrom of 1938, the father's business was devastated and looted. A few weeks later, Isidor Sitzmann had to give up his store. The family fled to Frankfurt am Main in the alleged protection of the city and the large Jewish community. Her last address in Frankfurt was a two-room apartment in Quinkestr. 7, today Königswarter Street.

Klara Sitzmann already lived in Frankfurt am Main from 1936. In the early summer of July 1938 she gave birth to her son Peter at the Jewish Hospital in Frankfurt am Main, Gagernstraße 36. She lived with him until 30 August 1938 in the home "Isenburg" of the Jewish Women's Association. Then she returned to Frankfurt am Main. Peter stayed in Neu-Isenburg. In May 1939 Klara succeeded to escape to England where she died in January 2004.
