Which company opened the first fast food hamburger chain in 1921?

White Castle opened the first fast-food hamburger chain in 1921. The first restaurant opened in Wichita, Kansas, through the partnership of cook Walter Anderson and businessman Billy Ingram.

White Castle’s innovation was not simply selling hamburgers quickly. It developed a repeatable system: a limited menu, small square burgers, standardized preparation, compact restaurant designs, and centralized supplies. The original hamburger cost five cents, making it an inexpensive meal for urban workers and travelers.

The company also worked to overcome the hamburger’s poor reputation after public concerns about meatpacking and sanitation. Bright white buildings, stainless-steel interiors, spotless uniforms, and visible cooking helped signal cleanliness. White Castle is often confused with McDonald’s because McDonald’s later became far more globally prominent, but McDonald’s began decades afterward. White Castle’s system helped establish the model later chains expanded through franchising and mass marketing.
