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.
The idea of using the telegraph to transmit a time signal for longitude determination was suggested by François Arago to Samuel Morse in 1837, [85] and the first test of this idea was made by Capt. Wilkes of the U.S. Navy in 1844, over Morse's line between Washington and Baltimore. [86]
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]
The transcontinental telegraph was completed on Oct. 24, 1861, making possible instant communication between the coasts possible for the first time. It rendered the Pony Express obsolete.
The telegraph line immediately made the Pony Express obsolete, which officially ceased operations two days later. The overland telegraph line was operated until 1869, when it was replaced by a multi-line telegraph that had been constructed alongside the route of the first transcontinental railroad.
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 ...
On this day in 1911 the first telegram was sent around the world via a commercial service from the New York Times' office to test how fast a message could travel through a dedicated cable.
