Developed in the 1830s and 1840s by Samuel Morse (1791-1872) and other inventors, the telegraph revolutionized long-distance communication. It worked by transmitting electrical signals over a wire laid between stations.
When was the single wire telegraph invented?
The archetype of this category was the Morse system, invented by Samuel Morse in 1838, using a single wire. At the sending station, an operator would tap on a switch called a telegraph key, spelling out text messages in Morse code.
Who invented non electrical telegraph?
This system was further improved by the American inventor Thomas Alva Edison, who patented a quadraplex telegraph system in 1874 that permitted the simultaneous transmission of two signals in each direction on a single line.
