Plaque commemorating invention of the cheeseburger in Pasadena dedicated at LA Financial Credit Union

In 1924, teenaged Lionel Sternberger put cheese on a hamburger and sold it to a delighted customer at his father’s roadside stand, The Rite Spot, at 1500 West Colorado Boulevard in Pasadena. “The Aristocratic Burger” at the Rite Spot is the first recorded instance of a hamburger with cheese being cooked and served to a customer. The Rite Spot is long gone. The site where it stood is now home to the LA Financial Credit Union. On January 5, 2017, the Pasadena Chamber of Commerce and LA Financial Credit Union unveiled a plaque commemorating the invention of the cheeseburger by young Mr. Sternberger. LA Financial Credit Union is on the site fo the original Rite Spot

Pasadena Mayor Terry Tornek was on hand to welcome guests and take part in the dedication ceremony. LA Financial Credit Union Vice President Amanda O'Brien and Pasadena Chamber CEO Paul Little also were part of the dedication.

The Pie ‘n Burger truck was on hand serving cheeseburgers to those in attendance. 20% of the proceeds from the sale of burgers was donated to Ronald McDonald House Pasadena.

The plaque unveiling kicked off Cheeseburger Week® in Pasadena.

We are very pleased that LA Financial Credit Union is allowing us to memorialize the invention of the cheeseburger on the site of the original Rite Spot in Pasadena. In the city where Julia Child was born and the world’s attention is focused on New Year’s Day, we thought it appropriate to commemorate the invention of the cheeseburger, as well.

The invention of the cheeseburger at the Rite Spot has been documented by the Los Angeles TimesTime magazine, cheese-burger.netHamburger Heaven: the Illustrated History of the Hamburger and The San Gabriel Valley Tribune. In2011, CNN carried the story of sixteen-year-old Lionel Sternberger and the creation of a culinary sensation. “The Aristocratic Burger: A Hamburger with Cheese” originally sold for fifteen cents at The Rite Spot in Pasadena.
