Leap Into Freedom, Peter Leibing, 1961

In order to stop the East Germans from fleeing the Soviet section of Germany post Second World War, East German leader Walter Ulbricht had a barbed-wire-and-cinder-block barrier thrown up in early August 1961. Peter Leibing was tipped off that someone was going to defect, and he and other cameramen gathered and watched as a West Berlin crowd enticed 19-year-old border guard Hans Conrad Schumann, yelling to him, “Come on over!” Schumann was the first reported East German soldier to flee.
