The 15-Cent Hamburger That Conquered the World
On April 15, 1955, milkshake-mixer salesman Ray Kroc opened his first McDonald's franchise in Des Plaines, Illinois — launching the template for the modern fast-food world.
The most important restaurant opening of the 20th century sold hamburgers for fifteen cents.
On April 15, 1955, in the Chicago suburb of Des Plaines, Illinois, a 52-year-old milkshake-mixer salesman named Ray Kroc opened the doors of his first McDonald's franchise. The red-and-white tiled building at 400 North Lee Street, with its golden arches and a sign boasting "Over 1 Million" hamburgers sold, would become the template for the modern fast-food world — the restaurant McDonald's itself calls its original, though it was actually the ninth.
Kroc hadn't invented McDonald's. That belonged to brothers Richard and Maurice McDonald, whose drive-in in San Bernardino, California, had been running since 1940. Kroc sold them milkshake machines — and when they ordered eight of his Multimixers in 1954, he drove out to see what kind of operation needed that many. What he found was a marvel of streamlined efficiency: a tiny menu, an assembly-line kitchen, food that was fast, cheap, and identical every time. He talked the brothers into making him their franchising agent and founded McDonald's System, Inc. to sell the concept nationwide.
The Des Plaines store was his showcase. Fifteen-cent hamburgers — 1.6-ounce beef patties, ten to a pound. No carhops, no dishes: self-service, eat in your car or on your feet. And behind it all, Kroc's real invention — not the burger, but the system. He kept franchise fees low so ordinary operators could buy in, then enforced ruthless uniformity through detailed manuals: how thick the patties, how the potatoes were stored and fried, how the restaurant was cleaned. Sloppy franchises were the reason early expansion stalled; Kroc's genius was making every store the same store. In 1961 he formalized the training in Hamburger University, first run out of a store basement.
The numbers tell the rest. By 1961 there were 230 McDonald's franchises; that year Kroc bought out the McDonald brothers for what amounted to $2.7 million, sales hit $37 million, and the march to ubiquity was on. The original Des Plaines building closed in March 1984 and was demolished; McDonald's built a replica museum on the site in 1985, which stood until flooding forced its demolition in 2018. (The oldest McDonald's still flipping burgers is the third one ever built, in Downey, California, from 1953.)
Fast food had existed before Kroc. But the franchise as an industry — the standardized, replicable, everywhere-identical chain — was his creation, and it reshaped how America eats, works, and drives. All from a fifteen-cent hamburger in a Chicago suburb, on April 15, 1955.
