Tesla vs. Marconi: Who Invented Radio

Nikola Tesla gave a public demonstration of the wireless transmission of energy on March 1, 1893. He had created an induction coil to transmit and receive radio signals. Years later while he was preparing to transmit signals at a distance, so was another inventor: Guglielmo Marconi.
