April 19 marks the 70th anniversary of the Warsaw Ghetto Uprising, in which a small number of armed Jews resisted the German Army as it attempted to clear out the ghetto for a month before being crushed. These photos were taken by Joe J. Heydecker, a German author and journalist who served as a simple soldier in the German Army. Using a Kine Exakta camera, he recorded many scenes that he saw during the war, including a series of photographs from the Warsaw Ghetto taken between November 11, 1941, and April 16, 1942. He continued to take photographs in spite of the ban issued in 1941 on independent photographers. (18 PHOTOS)
