CHEESEBURGER: PASADENA, CA - 1926
Hamburgers were based on meat patties eaten by nomadic Mongols under Genghis Khan in the 12th century. The humble cheeseburger, however, owes its inception to a cheeky, 16-year-old kid in Pasadena. Back in 1926, Lionel Sternberger, the son of the owner of a little sandwich joint called The Rite Spot, decided to slap a piece of American cheese on top of a burger patty as it was frying. Thus, the cheeseburger was born (although they called it a "cheese hamburger"), and Genghis Khan's spirit could be at peace, knowing that his work was finally complete.
