The sandwich name suggested by Esther Glickstein Rose in 1967 was Big Mac.
Rose worked as a 21-year-old advertising secretary at McDonald's corporate headquarters when she suggested the name for the chain's new double-decker hamburger. An earlier proposed name, “The Aristocrat,” was rejected, and “Blue Ribbon Burger” was also considered before Big Mac was selected.
The Big Mac was created by franchisee Jim Delligatti and introduced nationally in the United States in 1968. It used two beef patties, a sesame-seed bun with a middle section, lettuce, cheese, pickles, onions, and sauce.
Rose did not receive public recognition for many years, which helped create confusion about the name's origin. The product was developed in 1967 and nationally launched in 1968, so those dates describe different stages of the sandwich's branding history.
