Joseph Vacher (November 16, 1869 – December 31, 1898) was a French serial killer, sometimes known as "The French Ripper" or "L'éventreur du Sud-Est" ("The South-East Ripper") due to comparisons to the more famous Jack the Ripper murderer of London, England in 1888. His scarred face, accordion, and plain, white, handmade rabbit-fur hat became his trademark appearance.
