On April 22, 1967, a McDonald’s franchisee in Uniontown, Pennsylvania, debuts a double-decker burger that would soon be known around the world as the Big Mac. The price: 45 cents.

“The Big Mac resulted from our need for a larger sandwich to compete against Burger King and a variety of specialty shop concoctions,” noted McDonald's mastermind Ray Kroc in his 1977 autobiography Grinding It Out. “The idea...was originated by Jim Delligatti in Pittsburgh.”

Kroc would make a fortune from it, but first he stood in its way. Beginning in 1965, Delligatti had lobbied the company for a bigger burger and was repeatedly rebuffed. McDonald’s did allow him to experiment, but on one condition: Use only ingredients already on hand. He bent the rules anyway by ordering a three-part bun to better hold it all together.

The gamble worked. McDonald's took the Big Mac national in 1968.

By 1974, its build was immortalized in an advertising jingle many can still recite: “Two all-beef patties, special sauce, lettuce, cheese, pickles, onions, on a sesame-seed bun.”

By 1986, the Big Mac was so ubiquitous that The Economist introduced the Big Mac Index, using its price to compare currencies worldwide.

When Delligatti died at 98, obituaries celebrated the burger he created—and noted he reportedly ate at least one a week for decades.

All but lost to history, however, was another Delligatti invention recalled by Kroc: the Farkelberry Snickerdoodle, a cookie that never caught on. Maybe it just needed a better jingle.
