Electrical telegraph
Person
Artículo WikipediaFuente Dbpedia
An electrical telegraph is a telegraph that uses electrical signals, usually conveyed via dedicated telecommunication lines or radio. The electrical telegraph, or more commonly just telegraph, superseded optical semaphore telegraph systems, such as Claude Chappe's towers designed for communication among the French military, and Friedrich Clemens Gerke for the Prussian military, thus becoming the first form of electrical telecommunications. In a matter of decades after their creation, electrical telegraph networks permitted people and commerce to transmit messages across both continents and oceans almost instantly, with widespread social and economic impacts.
