"Although ancient people ate slices of bread on either side of some type of filling, the sandwich as we know it was born on Aug. 6, 1762, according to The Henry Holt Encyclopedia of Word and PhraseOrigins.
Englishman John Montagu was embroiled in one of his all-night card games when, around 5 a.m., he decided he was hungry. He didn't want to leave his cards untended, so he sent a servant to fetch him cold roast beef between two slices of toasted bread. A portable feast was born.
That explains the structure, but what about the name? It seems that Montagu, the inventor of this contribution to quick cuisine, was the fourth earl of Sandwich."
This is a very important lesson.
