Dairy Queen began in Joliet, Illinois.
The first store opened on June 22, 1940, revolutionizing ice cream with its soft-serve formula.

Origin Story

In 1938, near Moline, Illinois, John Fremont "J.F." McCullough and his son Alex invented a creamy soft-serve recipe. They tested it at friend Sherb Noble's ice cream shop in Kankakee, Illinois, selling over 1,600 servings on the first day—proof of its instant appeal. Convinced of its potential, they launched the inaugural Dairy Queen at 501 N. Chicago Street in Joliet, offering cones, sundaes, pints, and quarts.

That modest storefront sparked a franchise empire, growing from one shop to over 5,700 locations worldwide by blending nostalgia with innovation.

The Soft-Serve Secret

Unlike hard-packed scoops of the era, Dairy Queen's mix—curvier, lighter, and dispensed fresh—earned it the nickname "Queen of Dairy." Early menus stayed simple, focusing on that signature curl-on-top cone, letting the treat shine without distractions.

Legacy Today

From its Illinois roots, Dairy Queen now spans the U.S., Canada, Europe, and beyond, blending ice cream with burgers at Brazier locations. Fans still pilgrimage to Joliet's landmark site, celebrating how one family's hunch created a soft-serve dynasty.
