Introduction. Developed in the 1830s and 1840s by Samuel Morse (1791-1872) and other inventors, the telegraph revolutionized long-distance communication. It worked by transmitting electrical signals over a wire laid between stations.
One very early experiment in electrical telegraphy was an electrochemical telegraph created by the German physician, anatomist, and inventor Samuel Thomas von SÃ¶mmering in 1809, based on an earlier, less robust design of 1804 by Spanish polymath and scientist Francisco Salva Campillo.
