Morse telegraphs (1838 AD)In the United States, the telegraph was developed by Samuel Morse andAlfred Vail. Samuel F. B. Morse independently developed an electrical telegraph in 1836, an alternative design that was capable of transmitting over long distances using poor quality wire. His assistant, Alfred Vail developed theMorse code signalingalphabet with Morse. This was a practical electrical telegraph system, and subsequently electrical telegraphcame to refer to a signaling telegram - a system where an operator makes and breaks an electrical contact with a telegraph key, which results in an audible signal at the other end produced by atelegraph sounder,which is interpreted and transcribed by a human.
