John Montagu, 4th Earl of Sandwich

John Montagu, the 4th Earl of Sandwich, was an 18th-century British nobleman famous for his influence in politics and society. He is best known for popularizing the "sandwich," a food item consisting of meat or other fillings between slices of bread, which he reportedly ordered during long hours of gambling to eat without interrupting his activity. His name became synonymous with this convenient meal, which remains a staple today. Beyond this, he held various important positions, including First Lord of the Admiralty, helping shape British naval and political history.
