From Good News Network: Guglielmo Marconi and Good News In History, June 2
"125 years ago today, the Italian electrical engineer and inventor Marconi, applied for the first ever patent for a system of wireless communication. He is credited as the inventor of radio, and shared the 1909 Nobel Prize in Physics for contributions to the development of wireless telegraphy.
At age 20, Guglielmo began experimenting with a method to transmit and receive messages over a distance without wires at the family home—first, across the room, then down the corridor, then into the fields. A breakthrough came when Marconi discovered that a much greater range could be achieved by raising the height of his antenna and grounding his instruments—the system was capable of transmitting signals up to 2 miles (3.2 km), even over hills.
When Italian officials ignored his letter and instead evoked an insane asylum, Marconi left his birthplace of Bologna to go to England where he found the funds and support to convert his work into practical use. He became an entrepreneur, founding The Wireless Telegraph & Signal Company to innovate further.
His ‘Marconi's Law’ is the empirical relation between length of antennas and maximum signaling distance of radio transmissions, but with over 800 patents, he moved into radar and shortwaves, and visual wave amplification too, as one of the founders of the BBC."

I used to work in the radio communications industry and this is very important history for me.
