Hughes Telegraph
Mid-19th Century
Unlike the Morse telegraph, which used a key and a code of dots and dashes to represent alphabetic characters, the Hughes design operated by pressing a key for each letter of the alphabet, and the received message was printed on a strip of paper, using the actual characters of the message. This example was operated on the Paris - Milan line.
Very few survive today. Signed “Dumoulin - Froment a Paris.” French.
