Blösche became known to the world because he was photographed five times with SS forces that suppressed the Warsaw Ghetto Uprising, as published in the "Stroop Report". The most famous photograph portrays a boy surrendering in the foreground, and Blösche as the SS man who is facing the boy with a sub-machine gun in hand. The Report was used in prosecution of former Nazis for war crimes. For his war crimes, Blösche was convicted and sentenced to death; he was executed in Leipzig by East Germany on 29 July 1969.
