Can you imagine a world without television and radio? Not to mention cellphones, cordless phones, radar, microwave ovens, remote-control cars, and baby monitors?
All these devices rely on the transmission of radio signals through the air. And it was 100 years ago this Saturday that a young Italian inventor showed the globe-girdling potential of his wireless telegraph, or radio transmitter.
On January 18, 1903 the first public, two-way wireless communication between Europe and America occurred, and the dream of worldwide communication became reality.
The MIT Technology Review website has an article on this event. You can also read more The MIT Technology Review website has here.
This is the original message, sent January 18, 1903:
His Majesty King Edward VII
London, Eng.
In taking advantage of this wonderful triumph of scientific research and ingenuity, which has been achieved in perfecting a system of wireless telegraphy, I extend on behalf of the American people most cordial greetings and good wishes to all the people of the British Empire.
Theodore Roosevelt
