The annals of English history report that John Montagu was the 4th Earl of Sandwich.
Montagu often spent many long hours in London's gambling parlors. In 1762, he created the sandwich, by putting meat between two pieces of bread that allowed him to remain at the gambling table for long periods of time. The sandwich got its name from him.
It is no coincidence that November 3 is also the birthday of John Montagu, the fourth Earl of Sandwich.
