According to Enchanted Learning, a site that charts inventions, the potato chip was invented in 1853 by George Crum.
Crum was a Native American/African American chef at the Moon Lake Lodge resort in Saratoga Springs, New York.
French fries were popular at the restaurant during that time, and one day a diner complained that the fries were too thick. Although Crum made a thinner batch, the customer was still unsatisfied. The chef kept slicing them thinner, then fried them to a crisp, and seasoned them heavily with salt. By then, they were too thin to eat with a fork. Crum expected the fussy customer to dislike them, but the man praised them highly. So the potato chips were invented by accident. The chips became popular and subsequently became known as “Saratoga chips” or “potato crunches.”
