Did Thomas Edison improve the telegraph and the telephone?

Answer 1

Edison invented a form of wireless telegraphy called: Electrostatic Induction. Visit the following link for more information about wireless telegraphy: http://en.wikipedia.org/wiki/Wireless_telegraph

Answer 2

Thomas Edison was the inventor of the phonograph. The US inventor of the telegraph was Samuel Morse. Also, Morse didn't invent the telegraph, he just improved on it. His telegraph, built in 1836, allowed the use of small currents across long lines of ordinary wire. Many historians credit Morse's assistant Alfred Vail with designing crucial components of his system.

History of the Telegraph

Samuel Thomas von Sömmering constructed his (electrochemical) telegraph in 1809. In 1830, Joseph Henry demonstrated how a bell could be rung from a mile away using a small current and powered electromagnets (which were designed by Michael Faraday and by William Sturgeon). Baron Schilling had built an experimental telegraph in Russia and Carl Steinheil ran telegraph lines along a German railway in 1835. Between 1832 and 1837, while Morse and his associate Leonard Gale were developing their system, a different version was built by Charles Wheatstone and Sir William Cooke near London, which had certain electrical and phonetic limitations. When Alfred Vail developed the Morse Code system for Morse's 1836 telegraph, only the Panic of 1837 slowed its introduction. In 1838, he succesfully demonstrated the concept and in 1843, the US began work on the first city-to-city line between Washington and Baltimore. On May 24, 1844, the famous message that included "what hath God wrought" was sent from the US Supreme Court to the B&O railroad office in Baltimore. By 1850, more than 12,000 miles of telegraph lines had been strung in the US.

Answer 3

No. The telegraph was based on Hans Christian Oersted's discovery in 1819 that a wire carrying a current was able to deflect a magnetized compass needle. The Cooke and Wheatstone five needle telegraph of 1837 utilized this phenomenon. This apparatus, which is generally regarded as the first functional electric telegraph, was widely used in Great Britain for railroad signaling.

Tesla was into wireless things.

Answer 4

He set the basis and the standard of wireless communications. Any wireless device could not be without some of his patents. Tesla demonstrated "the transmission of electrical energy without wires" as early as 1891. When Tesla was 41 years old, he filed the first basic radio patent (No. US645576). The year was 1897.
