Tesla, Marconi, Slaby, Hertz, Lodge, Pupin, deForest … all these gentlemen were the fathers of radio! But the first public demonstration of the wireless transmission of intelligence was undoubtfully performed by Nikola Tesla in Philadelphia (the “Philadelphia lecture”) in February 1893. But his divergent thinking led him soon into the research of other areas, like phosphorescent lighting, remote control, electrotherapeutics. And he didn’t think of patenting his radio set-up until, well … Marconi was a clever man, he used inventions made by others (not only Tesla) … and then Marconi Ltd. was held first, for a long time, until today to be precise. But Marconi isn’t, Tesla is the father of radio.
