The electric telegraph led to Guglielmo Marconi's invention of wireless telegraphy, the first means of radiowave telecommunication, which he began in 1894. [5] In the early 20th century, manual operation of telegraph machines was slowly replaced by teleprinter networks.
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 patented invention proved lucrative and by 1851 telegraph lines in the United States spanned over 20,000 miles (32,000 kilometres). [13] Morse's most important technical contribution to this telegraph was the simple and highly efficient Morse Code , co-developed with Vail, which was an important advance over Wheatstone's more complicated ...
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.
George May Phelps (March 19, 1820 – May 18, 1888) was a 19th-century American inventor of automated telegraphy equipment. He is credited with synthesizing the designs of several existing printers into his line of devices [1] which became the dominant apparatus for automated reception and transmission of telegraph messages.
Charles Lyon Krum (1851/2 – September 25, 1937) [1] was a key figure in the development of the teleprinter, a machine which played a key role in the history of telegraphy and computing. [ 2 ] In 1902, electrical engineer Mr. Frank Pearne approached Mr. Joy Morton , head of Morton Salt , seeking a sponsor for Pearne's research into the ...
The Philippine Islands Telephone and Telegraph Company is American-owned which started operations in 1905 in the present-day Metro Manila. In 1928, merged with Cebu, Panay, and Negros Telephone and Telegraph companies to form the Philippine Long Distance Telephone Company (PLDT). In 1932, the colonial Philippine congress granted PLDT a 50-year ...
1844: Innocenzo Manzetti first suggests the idea of an electric "speaking telegraph", or telephone. 1849: Antonio Meucci demonstrates a communicating device to individuals in Havana. It is disputed that this is an electromagnetic telephone, but it is said to involve direct transmission of electricity into the user's body.
