History behind the term 'Cheeseburger'


The Birth of the Hamburger

In 1926, the term 'cheeseburger' had yet to be coined, but the iconic American hamburger was already making waves. The hamburger, a ground beef patty sandwiched between two pieces of bread, was becoming increasingly popular in fast-food joints and diners across the United States. It was a symbol of American culture and the rise of the fast-food industry.


Adding Cheese to the Hamburger

Two years prior, in 1924, a 16-year-old Lionel Sternberger revolutionized the hamburger world by adding a slice of cheese to a burger at the Rite Spot, his father's sandwich shop in Pasadena, California. This became the first recorded instance of someone adding cheese to a hamburger, laying the foundation for the future creation of the cheeseburger.


The First Printed Mention of 'Cheeseburger'

The term 'cheeseburger' first appeared in print in an advertisement in the Los Angeles Times on December 5, 1928. A restaurant called O'Dell's in Los Angeles advertised, 'O'Dell's Restaurant - Cheeseburgers - 10 cents.' This marked the first documented usage of the term, cementing its place in culinary history.


The Cheeseburger Gains Popularity

By the mid-1930s, the cheeseburger had gained significant popularity. It began appearing on menus in diners and restaurants across the country. The addition of cheese to the hamburger not only enhanced its flavor, but it also added a new level of indulgence and deliciousness that quickly captured the taste buds of Americans.


Cheeseburger Becomes a Staple American Food

During the 1940s, the cheeseburger solidified its position as a staple American food. The post-World War II era saw a surge in fast-food culture, with the cheeseburger at the forefront. The widespread popularity of fast-food chains like McDonald's, Burger King, and Wendy's during this time helped propel the cheeseburger into the hearts and stomachs of millions.


National Cheeseburger Day is Established

National Cheeseburger Day was established in 1987 by Lionel Sternberger's son, Charlie Sternberger. He wanted to honor his father's contribution to the world of hamburgers and cheeseburgers by designating a special day to celebrate this beloved culinary delight. Since then, every September 18th is celebrated as National Cheeseburger Day, a day when people indulge in their favorite cheeseburger creations.
