Coventina's History Thread: The Wireless Telegraph

In the 1800s, discoveries by the German-born Heinrich Hertz and Scottish James Clerk Maxwell set the stage for Guglielmo Marconi's notable invention: the wireless telegraph. Because the Italian's home country offered no support for his work, Marconi sought and received aid from the British government. Soon the dots and dashes of Morse code were spanning the English Channel via radio signals. In 1897, Marconi founded the Wireless Telegraph & Signal Company Limited. A few years later, Morse code for the letter "S" was sent from the shores of England and received in Newfoundland, Canada. Marconi's radio signal had raveled across the Atlantic Ocean!



PS: Marconi won the Nobel prize for Physics in 1909.
