sandwich: [18] John Montagu, the fourth Earl of Sandwich (1718–92), is said to have been so addicted to the gambling table that in order to sustain him through an entire 24-hour session uninterrupted, he had a portable meal of cold beef between slices of toast brought to him. The basic idea was nothing new, of course, but the Earl’s patronage ensured it a vogue, and by the early 1760s we have the first evidence of his name being attached to it: the historian Edward Gibbon in 1762 recorded in his diary how he dined at the Cocoa Tree and saw ‘twenty or thirty of the best men in the kingdom … supping at little tables … upon a bit of cold meat, or a Sandwich’.
