[size=18]Sandwich[/size]
The dish was named after John Montagu, 4th Earl of Sandwich, an English aristocrat, in the 18th century, although it is unlikely to have been invented by him. It is said that Lord Sandwich was fond of this form of food because it allowed him to continue gambling while eating.
But his biographer Rodger points out that the sole source of this rumour was gossip mentioned in a travel book by Grosley, and that at the period in question (1765) Lord Sandwich was known to be very busy and this food was for the purpose of eating at his desk.
Thank you, Ferngully.
