This McDonald’s franchisee in Uniontown, Pa., was said to have eaten one 540-calorie Big Mac (two all-beef patties, special sauce, lettuce, cheese, pickles, onions, on a sesame seed bun) a week for decades after coming up with the fast-food sandwich in 1967, according to this USA Today obit. The popularity of the sandwich, initially priced at 45 cents, fueled its availability in the rest of Delligatti’s Pennsylvania stores as well as nationwide in 1968. Billions have since been sold.
What's more, as one Network World reader wrote to us, Delligatti was actually something of an engineer, making him a good fit for this list of notables mainly from the tech world: "The Big Mac apparently had a problem with the top burger sliding off the stack. After experimenting, he found that adding the middle piece of bread stabilized the stack to preventing the self-disassembly."
