Telediagraph, The, an apparatus by which pictures can be reproduced by telegraph at long distances. It was used for the first time in January, 1898, in the New York "Herald" office, when a picture of Mayor Van Wyck was sent over a 6-mile circuit. Later pictures were sent to the "Herald" from Camden, N. J., and Key West, Fla. In the early part of 1899 a picture of the first gun fired at Manila was telegraphed from New York to Chicago, St. Louis, Philadelphia, and Boston simultaneously over a single wire.
