Were there any potato chips invented in the 1920s?

Yes, potato chips were popularized in the 1920s, particularly with the founding of the Lay's brand in 1932 by Herman Lay, who began selling them in the southern United States. However, the concept of frying thin slices of potatoes into chips dates back to the mid-19th century. The 1920s saw significant growth in the commercial production and marketing of potato chips, leading to their widespread popularity as a snack food.
