David Nencel was born into a religious Jewish family in Rypin (Poland) in 1916. In December 1942, he was deported to Auschwitz. He survived and was liberated from the Mauthausen satellite camp Ebensee in spring 1945. In Auschwitz, the SS put him into the Special Squad (Sonderkommando): prisoners who were forced to work at the crematoria and gas chambers. Speaking in 1996, he describes his deportation from the ghetto Maków Mazowiecki, the process of mass murder in Auschwitz-Birkenau and the anguish of Special Squad prisoners.
