Pringles were invented by Alexander Liepa and patented by Procter & Gamble in 1969.
Unlike conventional potato chips, Pringles are made from a dough containing dehydrated potatoes, corn, rice, and wheat. The dough is rolled into thin sheets, cut into uniform shapes, and fried. This process gives the crisps their distinctive saddle-like form and consistent size.
Procter & Gamble introduced the product nationally in the United States in 1968, initially calling it Pringles Newfangled Potato Chips. The brand later became associated with its cylindrical can, which helps protect the crisps from breaking. In 2012, Kellogg's acquired the Pringles brand from Procter & Gamble.
