The man who invented the McDonald's Big Mac burger has died, aged 98.
Michael "Jim" Delligatti
In 1967, Michael "Jim" Delligatti came up with the formula of having two lots of everything - beef patties, lettuce, cheese, pickles, onions and special sauce - in one burger.
He was one of the company's first franchisees, running stores in the US in the 1950s.
McDonald's has described him as a "legendary" person, who "made a lasting impression on our brand".
After inventing the burger, Jim Delligatti went on to run 48 McDonald's branches, making him one of the biggest franchisees in the company's history.
In 2007 he opened the Big Mac Museum, where visitors can be photographed in front of the world's largest Big Mac - which is more than four metres wide.
He passed away on Monday night in Pittsburgh, surrounded by his family.
