Hamburger & Cheeseburger

The origin of hamburger is unknown, but the hamburger patty and sandwich were probably brought by 19th-century German immigrants to the United States, where in a matter of decades it came to be considered an archetypal American food.

The trademark for the name "cheeseburger" was awarded in 1935 to Louis Ballast of the Humpty Dumpty Drive-In, in Denver, Colorado.
