The Men Who Laid The Cable That Shrank The World

Transatlantic telegraph cable history: the dangerous voyages, cable hands, and Great Eastern expedition that shrank the world. Before the Atlantic cable, a message from London to New York moved at the speed of steam. News, markets, military orders, and private grief crossed the ocean in roughly ten days. Then Victorian engineers, sailors, investors, factory workers, and telegraphists tried to pull those ten days down to minutes with one fragile copper nerve laid across two miles of black water. This Trade Theory industrial documentary follows the first transatlantic telegraph cable from dream to disaster to lasting success: Cyrus West Field's obsession, gutta-percha cable factories, USS Niagara, HMS Agamemnon, the failed 1857 and 1858 attempts, the dead line on the seabed, Lord Kelvin's instruments, Great Eastern's cable tanks, the 1865 break, the 1866 success, and the cable hands who turned the deep ocean into a workplace.
