Human hair

12 of 13
The Nazis went to sinister lengths to profit from the extermination of millions, and no possible resource was wasted. Human hair shorn from victims' scalps was gathered and sold to German factories to make cloth. At the time of the camp's liberation in January 1945, seven tons of hair were discovered ready to be transported for sale. In Block 4, mounds of human hair are preserved behind a glass case more than 67 feet long.
