In 1838, Steinheil installed a telegraph along the Nuremberg–Fürth railway line, built in 1835 as the first German railroad, which was the first earth-return telegraph put into service. By 1837, William Fothergill Cooke and Charles Wheatstone had co-developed a telegraph system which used a number of needles on a board that could be moved to ...
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.
Early proposals for an optical telegraph system were made to the Royal Society by Robert Hooke in 1684 [12] and were first implemented on an experimental level by Sir Richard Lovell Edgeworth in 1767. [13] The first successful optical telegraph network was invented by Claude Chappe and operated in France from 1793. [14]
Cooke and Wheatstone had their first commercial success with a telegraph installed in 1838 on the Great Western Railway over the 13 miles (21 km) from Paddington station to West Drayton. Indeed, this was the first commercial telegraph in the world. [10] This was a five-needle, six-wire [9] system. The cables were originally installed ...
Another electrical telegraph was independently developed and patented in the United States in 1837 by Samuel Morse. His assistant, Alfred Vail, developed the Morse code signaling alphabet with Morse. America's first telegraph was sent by Morse on January 6, 1838, across 2 miles (3 km) of wiring.
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.
The history of telecommunication began with the use of smoke signals and drums in Africa, Asia, and the Americas. In the 1790s, the first fixed semaphore systems emerged in Europe. However, it was not until the 1830s that electrical telecommunication systems started to appear. This article details the history of telecommunication and the ...
A restored Chappe telegraph in Marly-le-Roi. The Chappe telegraph was a French semaphore telegraph system invented by Claude Chappe in the early 1790s. The system was composed of towers placed every 5 to 15 kilometers. Coded messages were sent from tower to tower, with transmission being handled by tower operators using specially designed ...
