Vernichtungslager Kulmhof
Szymon (Shimon, Simon) Srebrnik (April 10, 1930 – August 16, 2006) was a Polish Jew and Holocaust survivor of the Chełmno extermination camp – a German Nazi death camp established in occupied Poland during World War II. Srebnik escaped after being shot in the back of his head at close range, two days before the Russians arrived in 1945. His testimony along with that of the few other witnesses was critical to prosecution of camp personnel and other Nazi officials, because of the destruction of evidence by the Germans of their mass extermination of Jews in Chełmno.
