“Word is Flashed from Roosevelt to King Edward” headlines The Evening World on January 19, 1903. Guglielmo Marconi and his crew successfully send the first transatlantic radio transmission from the US (accomplished a month earlier from Canada). Marconi, who has been experimenting since the 1890s, shares the 1909 Nobel Prize in Physics for “contributions to the development of wireless telegraphy.” Marconi radio operators aboard ships send out routine messages and distress signals via Morse code…including from the Titanic.
