Their sons escaped to the U.S. and U.K. In 1940, Walter and Lucy were forced to leave Rotterdam and moved to Bilthoven. In 1942, they were deported to Amsterdam and shortly after to Westerbork. On 4 May 1943, they were transported to Sobibor, where they were murdered upon arrival on 7 May. Walter was 64, Lucy 57.
