James McLamore and David Edgerton

James McLamore and David Edgerton founded Burger King in 1954, developing the 'Insta-Machine' conveyor-belt broiler and the iconic Whopper, establishing the foundation for the company's most globally recognized burger brand.

James McLamore and David Edgerton, two college friends, founded Burger King in Miami, Florida, in 1954. Recognizing the potential of the fast-food model, they sought to differentiate their concept through culinary innovation. They developed the 'Insta-Machine,' a revolutionary conveyor-belt broiler that allowed for the continuous, rapid flame-grilling of beef patties, leading to the creation of the Whopper in 1957. The Whopper’s larger size and flame-grilled flavor profile resonated deeply with consumers, allowing Burger King to rapidly expand and eventually go public in 1971. Their vision of a differentiated, flame-grilled burger experience remains the core identity of the brand today.
