In spring 1944, after losing nearly his entire family on the day they arrived at Auschwitz II-Birkenau, 22-year-old Dario Gabbai was assigned to one of the special units of Jewish prisoners required to work in the gas chambers and crematoria: the Sonderkommando.

Brandeis University Professor Dawn Skorczewski examines the differences between the testimonies of two sonderkommando survivors, Dario Gabbai and his cousin Morris Venezia.

Hungarian TV station RTL Klub will air the 2015 film Son of Saul for the first time this Saturday, September 24. The IWitness activity Sonderkommandó, Birkenau was designed as a companion activity to the film for Hungarian students.
