You probably haven't heard his name, but you likely have devoured his creation: two all-beef patties, special sauce, lettuce, cheese, pickles, onions, on a sesame seed bun.
Michael James "Jim" Delligatti, the McDonald's franchisee who created the Big Mac nearly 50 years ago, died Monday at home in Pittsburgh surrounded by his family, family spokeswoman Kerry Ford said Wednesday. Delligatti was 98.
Until his health trailed off the last couple of years, Delligatti ate at least one 540-calorie Big Mac a week, his son Michael said.
Delligatti's franchise was based in Uniontown, not far from Pittsburgh, when he invented the chain's signature burger in 1967 after deciding customers wanted a bigger sandwich.
Michael Delligatti said McDonald's executives told his father he could experiment with a bigger burger but only using products the restaurant already stocked.
"He was often asked why he named it the Big Mac, and he said because Big Mc sounded too funny," Delligatti said.
