Some prisoners kept diaries, recording life inside the camp, so that the world would one day know the story of what happened to them. Others collected evidence of the killings and events within the camp, burying it in the hope that one day someone would find the evidence of the atrocities. Prisoners had to be careful to make sure these form of indirect resistance went undiscovered by the SS guards and kapos.
Oskar Schindler (28 April 1908 – 9 October 1974) was a German industrialist and a member of the Nazi Party who is credited with saving the lives of 1,200 Jews during the Holocaust by employing them in his enamelware and ammunitions factories in occupied Poland and the Protectorate of Bohemia and Moravia. He is the subject of the 1982 novel Schindler's Ark and its 1993 film adaptation, Schindler's List, which reflected his life as an opportunist initially motivated by profit, who came to show extraordinary initiative, tenacity, courage, and dedication to save the lives of his Jewish employees.
