Originally in English it was a piece of meat between two slices of bread. The name is an eponymous (Spanish only with an accent) by John Montagu, Count of Sandwich (England, 1718 - 1792); that according to the bad tongues was a ludopath who not to abandon his card games carried meat cooked between breads for his lunches, because he could eat it with one hand while playing with the other. Today any "ingredient between breads" is called sandwich. See sandwich , English/sandwich .
