It is said that Sandwich was invented by John Montagu, 4th Earl of Sandwich in England. He was a card player. He enjoyed playing card games all day long and had reached the point of forgetting to eat and sleep. It was difficult for the servant to serve him any meals, so the servant put some vegetables, eggs and sausages between two pieces of bread and let him eat while playing cards.
