Nikola Tesla was the first who invented the radio in 1893 in Philadelphia, Franklin Institute and in Missouri, St. Louis. Also Tesla did experiments in Gerlach Hotel in 1896. In 1900 Nikola Tesla got patents for “an electrical transmitter” and “system of transmitting electrical energy”. From 1901 till 1903 Tesla was fighting with Guglielmo Marconi who invented radio first, but no one support it. In 1904 Tesla lost the patent. Only after 49 years (in 1943) “Supreme Court of the United States” restored Nikola Tesla patent and he officially became the man who invented the radio.
