Marconi Sends First Trans-Atlantic Transmission (1901)

Moment 56: Marconi Sends First Trans-Atlantic Transmission

On December 12, 1901 Italian engineer and inventor Guglielmo Marconi successfully sent the first radio signals across the Atlantic Ocean. A radio signal was sent from Poldhu, Cornwall and received 2,100 miles away in Newfoundland, Canada. The received signal was the Morse code for the letter “S.” International communication was forever revolutionized. Marconi’s technology was especially significant for ships at sea – one of the most notable moments being the SOS signal sent from the sinking Titanic in 1912.
