Potato chips are thin slices of potato, fried quickly in oil and then salted. According to snack food folklore, the potato chip was invented in 1853 by a chef named George Crum at a restaurant called Moon's Lake House in Saratoga Spring, New York.
Making potato chips was a lot of work, since the potatoes had to be peeled and sliced by hand. That all changed in the 1920s, though, with the invention of the mechanical potato peeler.
