Salomon Siegfried Lievendag was a son of David Lievendag and Karoline Rothschild. He was married to his cousin Rosetha Lievendag, a daughter of Willem Lievendag and Mientjen van Gelder. As far as known they had no children. They lived at Frank van Borselenstraat 18a in Rotterdam.
The nazi’s started the deportations in Rotterdam 30 July 1942. A few days earlier, 2000 Jews received therefore a call to report for “provision of additional work in Germany under police supervision”. Packed and loaded, 1120 people have reported at “Loods 24”, among them also Salomon Siegfried Lievendag and his wife Rosetha Lievendag. They received a call, reported themselves and were transferred to- and registered in Westerbork 31 July 1942. With another 1011 deportees they were put on transport 3 August to Auschwitz. On arrival there, presumably 6 August, they haven’t been killed immediately; it is likely that they were forced to work in Auschwitz before both were killed in Birkenau 1 September 1942.
