At Buchenwald, nearby citizens of Weimar were forced to walk 4 miles to the camp to witness pre-prepared staged props. Among these were "shrunken heads", "strips of tattooed human skin", "a pelvis bone ashtray" and "a human skin lampshade". The problem was that the sun shone through the lampshade, proving it was not human skin. There were no tattoos on the lampshade, or stitching seams. This lamp has since conveniently disappeared. Prisoners' heads were all entirely shaved due to issues with lice, thus the shrunken heads would not have had hair. Among those at Buchenwald was Billy Wilder, the famous American film director who was born Samuel Wilder in 1906 to a Polish/Jewish family. He wrote scripts for many German films until Adolf Hitler came to power in 1933. Wilder immediately realized his Jewish ancestry would cause problems, so he emigrated to Paris, then the U.S. After the National Socialists were defeated, he conveniently came back to Germany, to Buchenwald, with that grudge and a plot hatched.
