Chaim, an artist and sign painter, and his wife Chejne Eingelster came from Lithuania. In 1906, the couple moved to Munich together with Esther Lea Wainstein, Chejne Eingelster's daughter from her first marriage. From 1912, they lived in the house at what is now Fasangartenstraße 124. They were granted German citizenship in 1930. Esther Lea ran a tobacconist's shop in St.-Anna-Straße.
Immediately after the National Socialists came to power, the family's German citizenship was revoked and Esther Lea had to close her business in 1938. In 1939, she married Jakob Paul Sondhelm, who also had to give up his business, a metal wholesaler, due to pressure from the National Socialists. In April 1941, the Gestapo deported Chejne and Chaim Eingelster to Pilaski, where they were murdered. Esther Lea and Jakob Paul Sondhelm were deported to Auschwitz in July 1942 and presumably murdered there immediately upon arrival.
A memorial service for Jakob Paul and Esther Lea Sondhelm and for Chaim and Chejne Eingelster was held at the European School on 11 May 2022. Pupils from the S6 classes researched the biographies and presented the results of their project in an exhibition. Afterwards, Memorial Signs for the Eingelster and Sondhelm couples were placed at their former place of residence at Fasangartenstraße 124.
