John DiFronzo (born December 13, 1928), known as John "No Nose" DiFronzo is an American mobster and the boss of the Chicago Outfit. DiFronzo, a former enforcer and caporegime, first appeared in the criminal record in 1949. He got the nickname "No Nose" because he sliced off part of his nose while jumping through a window during a 1949 clothing store burglary. Reportedly, the police gave him back the missing part which was almost perfectly restored. Wikipedia
