The first form of sandwich is attributed to the ancient Jewish sage Hillel the Elder, who is said to have put meat from the Paschal lamb and bitter herbs inside matzo (or flat,unleavened bread) during Passover. The filling between the matzos served as a reminder to Israelites of their forced labor constructing Egyptian buildings. The first written usage of the English word appeared in Edward Gibbon's journal, in longhand, referring to "bits of cold meat" as a 'Sandwich'. It was named after John Montagu, 4th Earl of Sandwich, an 18th-century English aristocrat, although he was neither the inventor nor sustainer of the food. It is said that Lord Sandwich was fond of this form of food because it allowed him to continue playing cards, particularly cribbage, while eating without getting his cards greasy from eating meat with his bare hands.
