Czesław Mordowicz (2 Aug. 1919 – 28 Oct. 2001) was a Polish Jew incarcerated at the Auschwitz Camp. He managed to escape on 27 May 1944 together with Arnošt Rosin. They both wrote a report about their alleged experiences at Auschwitz, which was included in the War Refugee Board Report. (For more details, see the entries on Arnošt Rosin and the War Refugee Board Report.) After his escape, Mordowicz participated in a partisan uprising against the Slovak wartime government. He was arrested and again sent to Auschwitz, where he survived.
