Section of the First Transatlantic Cable, 1858

Telegraphs could be sent wherever wires could be hung in the 1850s, but hardwiring signals between transoceanic continents required a feat of engineering. In 1858, a team laid underwater cable across the Atlantic and sent a successful telegram. Though the cable soon failed, pieces were sold as souvenirs in Charles Tiffany's renowned jewelry store as symbols of speed and progress.
