The Jewish lawyer Carel Zadoks was the owner of the building Bovenkerkerkade 3 in Amstelveen. Carel Zadoks went into hiding with his family in Amsterdam in June 1941. He was executed in Camp Amersfoort on 7 November 1942. His widow survived the war.
Bovenkerkerkade 3 was taken over as Jewish real estate in 1942 by the Niederländische Grundstücksverwaltung (NGV). The NGV sold the building to NSB member Johannes Franciscus Spoor. He sold the building as an intermediary the same day (14 October) to NSB mayor Westendorff of Nieuwer-Amstel. The intention was that the municipality of Nieuwer-Amstel would buy the building, but this was rejected by the province. Westendorff bought it and sold it to the municipality at the end of 1943 as an official residence to make it an official official residence. The purchase was not final until August 1944. The municipality of Amstelveen owned an expropriated Jewish building, which it used as an emergency hospital at the end of the war. After the war, the municipality had to settle the purchase in the context of legal restitution of Jewish expropriated property with Zadoks' widow. The settlement on compensation between the municipality and Mrs. Zadoks lasted until 1949. A lawsuit between former mayor Westendorff and the municipality also dragged on for years about the recovery of financial damages, which the municipality won. The former mayor, as the first war buyer of the building, had to pay the municipality's costs.
