The thickness of an ordinary potato chip is 55/1000 of an inch. Ridged chips are 4 times thicker, 210/1000 of an inch.
The month and day are uncertain (probably August 24), but the year 1853 is certain. Native American Chef George Crum invented potato chips at Moon's Lake House in Saratoga Springs, New York.
Supposedly a particularly fussy customer kept sending his french fries back to the kitchen as being too thick. Finally, Chef Crum decided to cut the potatoes paper thin; and to his ultimate surprise, the customer loved them! Saratoga Chips, later called Potato Chips, were born.
Pringles Potato Chips were introduced in 1969 by Procter & Gamble. Pringles are made from potatoes that have been cooked, mashed, dehydrated and then reconstituted into a dough. Pringles are cut into a uniform size and shape, then packaged in air-tight canisters designed to extend their shelf life.
