The beginning of cheeseburgers

The beginning of cheeseburgers dates back to the 1920s.

A story suggests that Lione Sternberger invented the cheeseburger in 1926 while working at his father's Pasadena, a California sandwich soap, The Rite Spot.

It was during an experiment that he dropped a slice of American cheese on a sizzling hamburger and created the cheesy genius.

However, there is no food whose origin isn't debated and so is the same with cheeseburgers.

In another story a restaurant in Los Angeles, O'Dell's claims the first to place cheeseburgers on its menu in 1928.

Kaelin' Restaurant in Louisville claims they invented the slice of heaven in 1934.

Interestingly, the Humpty Dumpty Drive-In in Denver received a trademark for the name “cheeseburger” in 1935.

While food lovers have been celebrating the day by eating this cheesy goodness, many took to Twitter to share their joy.
