Who gave the Big Mac its name after McDonald’s introduced the burger in 1967?

Esther Glickstein Rose gave the Big Mac its name after McDonald’s introduced the burger in 1967.

Rose was a McDonald’s advertising secretary who suggested the name while she was a child. Her idea was selected for the company’s new larger hamburger, which had been developed by franchisee Jim Delligatti in the Pittsburgh area.

The name helped position the sandwich as a distinctive branded product rather than merely a bigger hamburger. Its two beef patties, middle bun, special sauce, lettuce, cheese, pickles, and onions gave McDonald’s a signature menu item that could be marketed consistently across restaurants.

Delligatti is sometimes incorrectly credited with naming the sandwich because he created the recipe. Ray Kroc also appears in many accounts because he led the corporation, but the naming credit belongs to Rose. The sandwich initially had regional testing before broader promotion.
