Guillermo Marconi is one of the most recognized researchers in history for inventing radio. Although he cheated.
Marconi was a famous Italian electrical engineer and inventor who was born in Bologna on April 25, 1874 and died in Rome on July 20, 1937.
It was one of the most important drivers of long-distance radio transmission. It is also famous for the formulation of the well-known "Marconi Law" and the development of radiotelegraphy and for the development of a wireless telegraphy or radiotelegraphy system.
Around 1894, Marconi studied the transmission and reception of electromagnetic waves, extending the distance between the transmitter and the receiver from 30 centimeters to more than 10 meters.
A year later he discovered that the reach of the reception could reach several kilometers thanks to a Hertz spark generator placed on top of a rod. Thus, he built an apparatus with a range of 2.5 kilometers, consisting of a Hertz spark generator and a receiver.
Disappointed by the little success of his invention in Italy, he went to the United Kingdom where he patented it in 1896. But in "his invention" he used seventeen patents from Nikola Tesla, the true inventor of the radio together with Julio Cervera.
Then he founded the Wireless Telegraph and Signal Company, Ltd., along with his cousin Jameson Davis, with whom they tried to promote their invention and get financing to perform new tests and improvements in its operation.
However, these objectives would change later in the commercial exploitation of the radio, changing the name of the company to Marconi's Wireless Telegraph Company, Ltd. Marconi and Davis continued working to improve the reach of the emissions, overcoming the barrier of 16 kilometers that separate the United Kingdom from the European continent.
In 1903 he began transmitting messages from end to end of the United States. In 1904 he agreed with the British Post Office the commercial transmission of messages by radio and launched the first oceanic newspaper, which received the news by radio aboard ships.
The radio reached over 11,000 kilometers away in 1910. It had an important role that helped save hundreds of lives in wrecks like the Titanic. Marconi's name became famous throughout the world.
The value of radio was further reinforced because of World War I. In 1915 the Italian government commissioned Guglielmo Marconi for wireless military communications from his army.
After the war, he spent several years working on his yacht, Elettra, prepared as a laboratory, in experiments related to shortwave driving and testing the directed wireless transmission.
Marconi was awarded the Nobel Prize in Physics in 1909.
