Telegraph

Samuel Morse

Claude Chappe invented the non-electric telegraph in 1794
This was called the optical telegraph
In 1809 Sammuel Sommering invented a crude telegraph he invented this in Bavaria
The first telegraph in the USA was invented by Harrison Dyar in 1828
In 1825 British inventor William Sturgeon invented the electromagnet
Joseph Henry demonstrated the potential of William Sturegons electromagnet for long distance communication,in 1830
British physicists,William Cooke and Charles Wheatstone created a telegraph using the same principle of electromagnetism,in 1837
It was Samuel Morse who bettered Joseph Henry's invention
Samuel Morse's telegraph system that was a practical and commercial success
He proved that signals could be transmitted by wire
Samuel used pulses of current to deflect an electromagnet,that moved a marker to produce written codes on a strip of paper,This is called "The Morse Code"
