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.
The Aufseherinnen were female guards in Nazi concentration camps during The Holocaust. Of the 55,000 guards who served in Nazi concentration camps, about 3,700 were women. In 1942, the first female guards arrived at Auschwitz and Majdanek from Ravensbrück. The year after, the Nazis began conscripting women because of a guard shortage. The German title for this position, Aufseherin (plural Aufseherinnen) means female overseer or attendant.
