Samuel Morse (1791 - 1872) is an American inventor and painter. He was known for the invention of the electric telegraph, and improved telegraphic traffic by adding a relay at certain length intervals and thus enabled the transmission of signals over long distances. He also invented the dots and dashes code for the current transmission of the message, by which the message would be sent encrypted. In this way, the sending of the message has become instantaneous and possible over long distances.
