Jim Delligatti

Michael James Delligatti was born in Uniontown, Pennsylvania, on August 2, 1918, the son of James Delligatti, a farrier, cobbler and candy maker, and his wife, Lucille Dandrea. He was educated there and at Fairmont Senior High School in Fairmont, West Virginia. He served in Europe during World War II with the United States Army, where he was discharged after suffering from trench foot.[2][3][4][5]

After the war, Delligatti owned a drive-through restaurant in Newport Beach, California. After meeting Ray Kroc at a restaurant fair in 1955, Delligatti started as a McDonald's franchisee in 1957.[5][6] His franchise was based in Uniontown, Pennsylvania, about 40 miles (64 km) south of Pittsburgh, and his holdings grew to 48 stores.[1][2]

Delligatti conceived the Big Mac in 1965 in the kitchen of his first McDonald's franchise, on McKnight Road in suburban Ross Township. He started serving it at his Uniontown McDonald's in April 1967 for 45 cents.[2][3] By 1968, the Big Mac was on the menu of every American McDonald's, and in 1969, it accounted for 19% of total sales.[2] According to a 1970s jingle the burger contains: "two all-beef patties, special sauce, lettuce, cheese, pickles, onions on a sesame-seed bun."[2]

Interviewed by the Los Angeles Times in 1993, Delligatti agreed that he was not the inventor of the double-decker burger: "This wasn't like discovering the lightbulb. The bulb was already there. All I did was screw it in the socket."[3] In an interview with a Pittsburgh television station, Delligatti said that he had received no royalty payments for the creation of the Big Mac, but had received a plaque.[7] According to his son Michael, Jim ate a Big Mac every week.[8]

In 2007, Delligatti opened the Big Mac Museum, home to the "world's largest Big Mac", which is more than 13 feet (4 meters) across.[6] As of 2016, McDonald's sells about 550 million Big Macs in the U.S. every year.[2]

Delligatti was married twice, with his first marriage to Ann Vunora ending in divorce. They had one son. He and his second wife, Eleanor "Ellie" Carmody, had one son, five grandchildren, and eight great-grandchildren.[3][5] He died on November 28, 2016, at his home in Fox Chapel, Pennsylvania, at age 98.[3][4]
