Libero Grassi (July 19, 1924 – August 29, 1991) was an
Italian clothing manufacturer from
Palermo,
Sicily, who was killed by the
Mafia after taking a solitary stand against their
extortion demands. The businessman wrote an open letter to the local newspaper informing the extortionists that he was no longer willing to pay "
pizzo", a
Sicilian term for
protection money. Despite his brave stance against the Mafia, other business owners and shop keepers in Palermo refused to join his campaign. Grassi was gunned down in the street near his home eight months after writing the letter.
