Tuesday November 3rd is National Sandwich Day, and according to National Day Calendar, the sandwich is believed to be the namesake of John Mantagu, 4th Earl of Sandwich, following the claim that he was inventor of the sandwich. Before being known as a "sandwich," the food seemed to have simply been known as bread and meat or bread and cheese.
