John Montagu's family name rings no bells today, but his title does.
The fourth Earl of Sandwich was an impatient man who loved to gamble at cards.
He was so impatient,that when he got hungry, he refused to call time out; instead, he would order a servant to bring him two slices of bread with some meat in between them. That way he could play cards with one hand, and eat with the other.
Some scholars theorize that the sandwich, simple, tasty, and quick, helped fuel the Industrial Revolution, and the growth of the British Empire.
I wonder if he ever won his card games?
