Bogdan Bartnikowski was born in Warsaw in 1932. During the Warsaw Uprising, he and his mother were expelled from their home. The Germans initially sent them to a transit camp in Pruszków, and then deported them to Auschwitz where they were separated. On January 11, 1945, both were evacuated to Berlin-Blankenburg, where they were imprisoned until their liberation on April 22, 1945. After this, they returned to Warsaw. Bogdan Bartnikowski is the author of memoirs, including "Childhood Behind Barbed Wire.” In the „On Auschwitz" podcast, we invite you to listen to an interview with Bogdan Bartnikowski about his wartime experiences.
