Eventually communication reached an electronic state, and the telegraph was invented. Harrison Dyar, who sent electrical sparks through chemically treated paper tape to burn dots and dashes, invented the first telegraph in the USA. The telegraph was the first piece of equipment that allowed users to send electronic messages. A more developed version came from Samuel Morse, whose telegraph printed code on tape and was operated using a keypad and an earpiece. The pattern of communication soon became known as Morse code.
Edward Alfred Cowper
In 1879, Cowper invented the writing-telegraph; a device which allowed hand-written messages to be transmitted by telegraph. The exact position of the pencil of the operator at the sending-station was communicated to the writing-pen at the receiving-station through two wires, one giving the vertical and the other the horizontal position of the pencil.
