Whose idea was it to add cheese to the hamburger?

Adding cheese to hamburgers became popular in the late-1920s to mid-1930s, and there are several competing claims as to who created the first cheeseburger. Lionel Sternberger is reputed to have invented the cheeseburger in 1926 at the age of 16 when he was working as a fry cook at his father’s Pasadena, California sandwich shop, “The Rite Spot,” and “experimentally dropped a slab of American cheese on a sizzling hamburger.”

An early example of the cheeseburger appearing on a menu is a 1928 menu for the Los Angeles restaurant O’Dell’s which listed a cheeseburger smothered with chili for 25 cents. According to a report published by the independent public television station KCET, a person would have had the additional option to added spaghetti as an additional topping to their chili smothered cheeseburger for a total cost of 40 cents at this same eatery.

Other restaurants say they invented the cheeseburger. For example, Kaelin’s Restaurant in Louisville, Kentucky, said it invented the cheeseburger in 1934. One year later, a trademark for the name “cheeseburger” was awarded to Louis Ballast of the Humpty Dumpty Drive-In in Denver, Colorado. According to Steak ‘n Shake archives, the restaurant’s founder, Gus Belt, applied for a trademark on the word in the 1930s.

And here’s why the French have so much trouble with the word hamburger!
