Pringles

Pringles is an American brand of stackable potato-based chips invented by Procter & Gamble (P&G) in 1968 and marketed as "Pringle's Newfangled Potato Chips". The brand was sold in 2012 to Kellogg's. Pringles were sold in more than 140 countries. In 2012, Pringles were the fourth most popular snack brand after Lay's, Doritos and Cheetos (all manufactured by Frito-Lay), with 2.2% market share globally. History In 1956, Procter & Gamble assigned a task to chemist Fredric J. Baur (1918–2008): to develop a new kind of potato chip to address consumer complaints about broken, greasy, and stale chips, as well as air in the bags. Baur spent two years developing saddle-shaped chips from fried dough, and selected a tubular can as the chips' container. The saddle-shape of Pringles chips is mathematically known as a hyperbolic paraboloid. However, Baur could not figure out how to make the chips palatable, and was pulled off the task to work on another brand. In the mid-1960s another P&G researcher, Alexander Liepa of Montgomery, Ohio, restarted Baur's work and succeeded in improving the taste. Although Baur designed the shape of the Pringles chip, Liepa's name is on the patent. Gene Wolfe, a mechanical engineer and author known for science fiction and fantasy novels, helped develop the machine that cooked them.
