Jan Karski (1914 - 2000), Polish resistance fighter and professor.
“Although he had not saved individual Jews, The Commission for the Designation of the Righteous decided that he had risked his life in order to alert the world to the murder. He had incurred enormous risk in penetrating into the Warsaw ghetto and a camp, and then committed himself wholly to the case of rescuing the Jews. Karski’s case is quite exceptional in many ways. While other rescuers had taken the difficult decision to leave the side of the bystanders, not to remain silent and to stand up and act, Karski, after he reached the West, brought this dilemma to the doorstep of the free world’s leaders.”
