 Sir Charles Wheatstone and Sir William Fothergill Cooke invented the electric telegraph in 1837 . Also , the first commercial electrical telegraph is purported to have been constructed by Wheatstone and Cooke and opened on 9 April 1839 . Both inventors viewed their device as " an improvement to the [ existing ] electromagnetic telegraph " not as a new device .

 The telegraph arose from a collaboration between William Fothergill Cooke and Charles Wheatstone , best known to schoolchildren from the eponymous Wheatstone bridge . This was not a happy collaboration due to the differing objectives of the two men . Cooke was an inventor and entrepreneur who wished to patent and commercially exploit his inventions . Wheatstone , on the other hand , was an academic with no interest in commercial ventures . He intended to publish his results and allow others to freely make use of them . This difference in outlook eventually led to a bitter dispute between the two men over claims to priority for the invention . Their differences were taken to arbitration with Marc Isambard Brunel acting for Cooke and John Frederic Daniell acting for Wheatstone . Cooke eventually bought out Wheatstone 's interest in exchange for royalties .

 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 the first telegraph system to be put into commercial service . The receiver consisted of a number of needles which could be moved by electromagnetic coils to point to letters on a board . This feature was liked by early users who were unwilling to learn codes , and employers who did not want to invest in staff training .

 Samuel Morse independently developed a version of the electrical telegraph that he unsuccessfully demonstrated on 2 September 1837 . His code was an important advance over Wheatstone 's signaling method . The first transatlantic telegraph cable was successfully completed on 27 July 1866 , allowing transatlantic telecommunication for the first time .

 A revolution in wireless communication began in the first decade of the 20th century with the pioneering developments in radio communications by Guglielmo Marconi , who won the Nobel Prize in Physics in 1909 . Other notable pioneering inventors and developers in the field of electrical and electronic telecommunications include Charles Wheatstone and Samuel Morse ( telegraph ) , Alexander Graham Bell ( telephone ) , Edwin Armstrong , and Lee de Forest ( radio ) , as well as Vladimir K. Zworykin , John Logie Baird and Philo Farnsworth ( television ) .
