Oskar Schindler – one of the most famous rescuers of Jews during the Holocaust;

Georg Elser – a German carpenter who planned and carried out an elaborate assassination attempt on Adolf Hitler and other high-ranking Nazi leaders on 8 November 1939 at the Bürgerbräukeller in Munich. Unfortunately it didn't work and he was killed in a nazi concentration camp.

Pope John XXIII, born Angelo Giuseppe Roncalli, served as the 261st pope from 1958 to 1963 and is best known for initiating the Second Vatican Council, which brought significant reforms to the Catholic Church. The man who changed the church forever.
