Wireless Telegraphy by Tesla's System was used in Portugal in 1901
Wireless Telegraphy by Tesla's System was used in Portugal in 1901 to communicate between New Jersey and the Portuguese Coast. Mr. Jorge Silva, known Radio program designer, in a radio station in Portugal, found this Portuguese newspaper periodical from 1901 below:
Translation in English by Jorge Silva: "Wireless
Telegraphy in Portugal
Nikola Tesla is the Father of Radio, not Marconi
The significance of this article is that Marconi made a transatlantic transmission on December 12, 1901. Tesla's system, according to this article, was responsible for transmission before Marconi and was successfully used in Portugal to communicate over the Atlantic.
As early as 1892, Nikola Tesla created a basic design for radio. On November 8, 1898 he patented a radio controlled robot-boat. Tesla used this boat which was controlled by radio waves in the Electrical Exhibition in 1898, Madison Square Garden.
Tesla's robot-boat was constructed with an antenna, which transmitted the radio waves coming from the command post where Tesla was standing. Those radio waves were received by a radio sensitive device called coherer, which transmitted the radio waves into mechanical movements of the propellers on the boat.
Tesla changed the boat's direction, with manually operated controls on the command post. Since this was the first application of radio waves, it made front page news, in America, at that time.
Most of us, think of Guglielmo Marconi as the father of radio, and Tesla is unknown for his work in radio. Marconi claimed all the first patents for radio, something originally developed by Tesla. Nikola Tesla tried to prove that he was the creator of radio but it wasn't until 1943, where Marconi's patents were deemed invalid; however, people still have no idea about Tesla's work with radio.
