The Cooke and Wheatstone telegraph was an early electrical telegraph system dating from the 1830s invented by English inventor William Fothergill Cooke and English scientist Charles Wheatstone. It was a form of needle telegraph, and the first telegraph system to be put into commercial service. The receiver consisted of a number of needles that ...
The electric telegraph was slower to develop in France due to the established optical telegraph system, but an electrical telegraph was put into use with a code compatible with the Chappe optical telegraph. The Morse system was adopted as the international standard in 1865, using a modified Morse code developed in Germany in 1848. [1]
The timeline of North American telegraphy is a chronology of notable events in the history of the electric telegraphy in the United States and Canada, including the rapid spread of telegraphic communications starting from 1844 and completion of the first transcontinental telegraph line in 1861.
At the Speedwell Ironworks in Morristown, New Jersey on January 11, 1838, Morse and Vail made the first public demonstration of the electric telegraph. Although Morse and Alfred Vail had done most of the research and development in the ironworks facilities, they chose a nearby factory house as the demonstration site.
The Electric Telegraph Company (ETC) was a British telegraph company founded in 1846 by William Fothergill Cooke and John Ricardo. It was the world's first public telegraph company.

Sir Francis Ronalds FRS (21 February 1788 – 8 August 1873) was an English scientist and inventor, and arguably the first electrical engineer. [1] He was knighted for creating the first working electric telegraph over a substantial distance. [2]
Francis Ronalds conducted the first demonstration that an electric telegraph could be operated over a substantial distance in his Hammersmith garden in 1816. He used eight miles of iron wire strung between wooden frames. High-voltage friction machines were his power source. Ronalds offered his system to the Admiralty.
