Guglielmo Marconi

Italian-born founder of the [Marconi corporation]?. The 1909 recipient of the Nobel Prize in physics. Although many scientists and inventors contributed to the invention of wireless telegraphy, including Ørsted, Faraday, Hertz, Tesla, Edison, and others, Marconi's was the first practical system to achieve widespread use, so he is often credited as the "father of radio".

He recieved the first trans-Atlantic radio signal on December 12 1901 in Newfoundland, Canada using a 400-foot kite-supported antenna to recieve and a spark-gap transmitter using a frequency of approximately 500KHz; it was Morse code for the letter "S." Dr. [Jack Belrose]? has recently contested this, however, based on theoretical work as well as an actual reenactment of the experiment; he believes that Marconi heard only random atmospheric noise and mistook it for the signal. Marconi didn't achieve fully reliable transatlantic communication until 1907.
