The History of the Burger
Insurance salesman Edgar Ingram and cook Walter Anderson open the first White Castle hamburger stand in Wichita, Kansas. Their burgers, that sold for 5 cents, consisted of thin ground-beef patties cooked on a griddle, caramelized onions piled on top, and served on a spongy yeast bun. They later developed a smaller version about 2 ½ inches in diameter called a “slider” that was sold by the bag.
