John Montagu, the 4th Earl of Sandwich, is credited with popularizing and giving his name to the sandwich. However, he was not credited with inventing the concept of placing ingredients between bread slices. The story goes that John Montagu, an 18th-century English nobleman, was a passionate gambler who didn't want to leave the gaming table to have a proper meal. To avoid greasy fingers from interfering with the cards, he requested his servants to bring him some meat placed between two slices of bread. This convenient meal option became popular among others, and it was eventually named after him as the "sandwich." While the exact historical accuracy of this account is debated, the term "sandwich" did indeed become associated with this food preparation method.
