This is maybe one of the most powerful pictures I have ever seen. The numbers on the arms are from prisoners of Nazi concentration camps. The numbers replaced their names while at the camps and they were tattooed on so that they could be easily tracked by the Germans. This is why we study history. So this never happens again.
Robert Capa - Chartres, France, August 18th, 1944: Just after the liberation of the town, this French woman who had had a baby with a German soldier has her head shaved as punishment. During the middle ages, this mark of shame, denuding a woman of what was supposed to be her most seductive feature, was commonly a punishment for adultery. Shaving women's heads as a mark of retribution and humiliation was reintroduced in the 20th century and was widespread post WW2.
