Pennsylvania McDonald's franchisee who created Big Mac dies
Delligatti's franchise was based in Uniontown, about 40 miles south of Pittsburgh, when he invented the chain's signature burger with two all-beef patties, "special sauce," lettuce, cheese, pickles, onions on a sesame seed bun.
Delligatti told The Associated Press in 2006 that Oak Brook, Illinois-based McDonald's resisted the idea at first, because its simple lineup of hamburgers, cheeseburgers, fries and shakes were selling well.
