Joseph Lonardo, also known as "Big Joe", was an Italian mobster in the United States, who became the first crime boss of the Cleveland crime family, which he structured from a number of competing organized crime gangs. When national Prohibition began in 1920, Lonardo became a dealer in corn sugar, an essential ingredient in the manufacture of corn whiskey. Lonardo became a "sugar baron" by driving other legitimate corn sugar merchants out of business, encouraging home distillation, and using intimidation, murder, and theft to eliminate or drive his criminal competitors out of business.
