According to the Sterbebücher of Auschwitz Ludwig Stern died on 24 August 1942. It is possible this date is different from the official day of death as established after the war by the Department of Justice.
I ask you to correct Stern's date of death: Stern died on August 26th 1942. I'm sure that this date is the right one because I got Stern's document of death from the ITS in Bad Arolsen.
Stern was deported on July15th 1942 from Westerbork to Auschwitz together with his wife Jansje Vorst.
