KZ Plaszow
Through this connection to Schindler, Pfefferberg was employed in Schindler's factory near the Kraków-Płaszów concentration camp outside Kraków. This enabled him to survive the extermination of 3 million Polish Jews, during which his parents, sister, brother-in-law and many other relatives were murdered. Pfefferberg described Schindler as "a modern Noah," who was able to save a number of Kraków Jews from deportation to the nearby extermination camp at Auschwitz. Those he saved became known as "Schindlerjuden" or "Schindler's Jews".
