Polish police have reported that the infamous iron sign from the entrance to Auschwitz, a Nazi concentration camp where more than a million people perished during World War II, has been stolen. The wrought iron sign reading "Arbeit Macht Frei", meaning "Work Sets You Free," was made by Polish prisoners and first erected in 1940. Hundreds of thousands of prisoners passed under the sign as they entered the camp during the Holocaust; most were either murdered or worked to death. The sign's theft comes just days after the German government pledged 86 million dollars (60 million euros) to an endowment fund to help preserve the camp.
