As a boy, Marconi was fascinated with radio waves and learned Morse code, the language of the telegraph. A retired telegraph operator taught him how to tap messages on the telegraph machine. At the age of 20, Marconi realized that no one had invented a wireless telegraph. Determined to find a way to use radio waves to send wireless messages, Marconi found his calling. And, thanks to his persistence, on December 12, 1901, for the first time ever, a wireless signal travelled between two continents. The rest is history, brought to life in Tundra''s Great Idea series.
