Cooke and Wheatstone telegraph
The Cooke and Wheatstone telegraph was an early electrical telegraph system dating from the 1830s invented by English inventor William Fothergill Cooke and English scientist Charles Wheatstone. It was the first telegraph system to be put into commercial service. The receiver consisted of a number of needles which could be moved by electromagnetic coils to point to letters on a board. This feature was liked by early users who were unwilling to learn codes, and employers who did not want to invest in staff training.

Edgar Allan Poe, Herman Melville, Walt Whitman lived and taught and privately lectured there, Winslow Homer painted there, and architects Alexander Jackson Davis and Richard Morris Hunt had offices there.
