Apparently, fellow artist Paul Gauguin did.  In the latest art news, there was a dual and Gauguin, who was an expert fencer cut off the ear. But in order to protect Gauguin, they both agreed to tell the police that it was Gogh himself that cut off his own ear.  There’s even a book released entitled Van Gogh’s Ear that has been heavily researched.  For all you art fans out there, I’m sure this is one sure to please.
