The telegraph transmitted electrical signals through a wire placed between two stations. Samuel Morse, from Washington, D.C., invented the telegraph along with an alphabet of dots and lines called “Morse Code”. The first telegraph transmitted message came from Washington, D.C. and went all the way to Baltimore, Maryland. By 1866, a telegraph line was placed in the Atlantic Ocean, spreading from the United States to Europe. The telegraph was revolutionary for long distance communication and became the base invention for the telephone, the fax machine and the internet.
