Wilhelm Weber House, 14,15 Schlossstrasse, Wittenberg Memorial to Wilhelm Weber, Wittenberg Post Office Wilhelm Eduard Weber (/ ˈ v eɪ b ər /; [1] German: [ˈvɪlhɛlm ˈeːdu̯aʁt ˈveːbɐ]; 24 October 1804 – 23 June 1891) was a German physicist and, together with Carl Friedrich Gauss, inventor of the first electromagnetic telegraph.
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]
Many electrical telegraph systems were invented that operated in different ways, but the ones that became widespread fit into two broad categories. First are the needle telegraphs, in which electric current sent down the telegraph line produces electromagnetic force to move a needle-shaped pointer into position over a printed list.
Samuel Morse independently developed a version of the electrical telegraph that he unsuccessfully demonstrated on September 2, 1837. His code was an important advance over Wheatstone's signaling method. The first transatlantic telegraph cable was successfully completed on July 27, 1866, allowing transatlantic telecommunication for the first ...
An early experiment in electrical telegraphy was an 'electrochemical' telegraph created by the German physician, anatomist and inventor Samuel Thomas von Sömmerring in 1809, based on an earlier, less robust design of 1804 by Spanish polymath and scientist Francisco Salva Campillo. [10]
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.
In 1836 Elderton, David Alter invented the electric telegraph, one year before the popular Morse telegraph was invented. David rigged the telegraph between his house and his barn. He was interviewed about the discovery going unobserved by other inventors and said: "I may say that there is no connection at all between the telegraph of Morse and ...
Keyboard perforators were a development from Charles Wheatstone's perforator of 1858, [3] a hand-operated device which produced a punched paper tape for use in automatic telegraph transmitters. Soon after, he set up the Kleinschmidt Electric Company. [4] With George Seely, he developed signaling equipment for railways.
