Simon Srebnik (Łódź, April 10, 1930 – Tel Aviv, August 16, 2006) was a Polish-Israeli Holocaust survivor, known for his testimony in the film 'Shoah'. Deported to the Chełmno extermination camp at the age of thirteen, he was forced to work in the Sonderkommando, managing the corpses. His young age and his voice earned him the nickname 'Spinne' (spinning top), and he was made to sing German military songs for his captors. Shortly before the camp's liberation, he was gravely wounded by a gunshot to the head during a mass execution but survived by pretending to be dead, becoming one of the very few survivors of Chełmno. After the war, he moved to Israel. His work as a historical witness culminated in his participation in Claude Lanzmann's 1985 documentary 'Shoah'. The iconic scene in which Srebnik returns to the Ner River, singing the same melody he sang as a prisoner, is considered one of the most powerful moments in cinema on the memory of the Shoah and represents his primary source of worldwide recognition.
