He willingly entered the Warsaw Ghetto and a concentration camp, in order to bear witness. He risked his life to carry the terrible news across occupied Europe. He personally told Anthony Eden and Franklin D. Roosevelt what was happening to the Jews in Poland. Jan Karski’s heroism does not belong to a single nation. It is written in the Talmud: “He who saves one life saves the entire world.”

Karski: How One Man Tried to Stop the Holocaust is the only biography published with the full cooperation of Jan Karski, who died in 2000. Thoroughly documented, it is based on years of research in the archives of five different countries as well as numerous interviews with Professor Karski.
