Though he didn’t start the idea of putting filling between two slices of bread, John Mantagu, the 4th Earl of Sandwich, got the name to stick. Supposedly, in 1762, the frequently-gambling earl wanted something to eat without having to leave the card table, and likely got the idea through similarly-stacked morsels he’d seen on Mediterranean travels. Once he started eating these regularly, they took off in popularity, with people ordering “the same as Sandwich” which got shortened to “sandwich.”
Grapevine stems are naturally twisted and convoluted, quite the opposite of straight and direct telegraph wires. The connection is that to describe something which was “heard through the grapevine” actually descends of the older term “The Grape Vine Telegraph Line.” This reference, which came about soon after telegraph technology grew, referred to information transmitted through the often-meandering and indirect person-to-person channels as opposed to straight-from-the-source communications. Nonetheless, these “grapevine” channels via African-Americans proved useful to Union leaders during the American Civil War in obtaining clandestine military information, and likely in many other military efforts since.
