On August 24, 2024, Stolpersteine ("stumbling stones") were laid in Łódź in the presence of Leon Weintraub for his sister Rajzla (Ruska), who was murdered in Stutthof, and his mother Nacha (Natalia), who was murdered in Auschwitz-Birkenau.
The Weintraub family had to live in the Litzmannstadt ghetto from the winter of 1939/40 and were deported to Auschwitz-Birkenau in August 1944. Leon Weintraub escaped death by gassing by joining a prisoner transport to the Groß-Rosen concentration camp. In February 1945, he was transferred to Flossenbürg and shortly afterwards to Natzweiler-Struthof concentration camp. After escaping from another transport, he was liberated in Donaueschingen. Three older sisters survived imprisonment in Bergen-Belsen concentration camp.
The laying of the stumbling stones was initiated by Marcus Valder, who accompanied the event together with a Cologne school class and the children's choir of the city of Łódź.
