Telegraph system was original invented without electricity. It was a system of semaphores, and other signaling apparatus, set within physical sight of one another. Samuel F. B. Morse conceived of an electromagnetic telegraph in 1832 and constructed an experimental version in 1835. Morse and his partners Leonard D. Gale and Alfred Vail created a model electric telegraph which transmitted patterned "dot" and "dash" pulses over a wire. He did not construct a truly practical system until 1844, when he built a line from Baltimore to Washington, D.C. The first message via telegraph in the United States, "What hath God Wrought?" Shortly after this successful test, telegraph lines were erected to connect the major eastern and northern cities. This invention profoundly affected the development of the West. It was an important discovery and helped make railroad travel safer, and allowed businessmen to conduct their operations more profitably. This invention helped change the world because it brought about the invention of the Morse code. This made the telegraph a major asset to the military, being used first at Varna during the Crimean War in 1854. It was widely used in the American Civil War, where rapid deployment techniques for land-lines were developed; the Spanish-American War found the first use of telegraphy for newspaper correspondents (1898). The first military use for radio telegraphy was during the Russo-Japanes War in 1904 – 5. I often wonder how did the inventor come up with these idea and what was it about their society that they felt needed to change? I know I have a lot of suggestion that I think would better our society in the 21th century but I wouldn’t know where to start! Would you?
