On April 22, 1967, a McDonald’s franchisee in Uniontown, Pennsylvania,
debuted 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.” McDonald’s
took the Big Mac national in 1968.
