Nathan and Heintje were religious Jews who raised their six children (two of whom died young) in Jewish traditions. Active members of the Jewish community in Lochem, Nathan chaired the Gewre Talmoed Thora, a Bible study association, while Heintje collected funds in 1922 for victims of pogroms in Ukraine and was president of Bigdei Koudesj, managing ritual items at the Lochem synagogue. Beyond the Jewish community, Heintje was involved in the Municipal Committee for Preventing School Truancy from 1923 to 1935. In April 1942, Nathan and Heintje moved to Zwolle to live with a daughter and son-in-law, but were forced to relocate to Amsterdam eight months later. Despite their work for the Jewish Council, they were deported to Westerbork on May 25, 1943, and then to Sobibor, where they were killed upon arrival on July 23, 1943. Their sons Manuel and Simon Philip suffered the same fate that day, while son Salomon was murdered earlier in July. Their children Aaltje, Alexander, Rika, and Rosette survived the war in hiding.
