Tesla's Demonstration of Radio



In 1891, Nikola Tesla gave his first demonstration of wireless technology. Two years later, on March 1, 1893, Tesla went public with his radio technology demonstrations in St. Louis. Tesla had first demonstrated wireless transmissions in 1891. Just days before the public presentation in St. Louis, Tesla privately addressed the Franklin Institute in Philadelphia, describing in detail the principles of early radio communication. The key to the technology was the Tesla induction coil. There is some question about who actually invented radio. Guglielmo Marconi is often cited as the inventor of radio because of his work on long distance transmissions In 1895, Tesla suffered a catastrophic fire in his lab, setting his experiments back for a time. Around the same time, Marconi was conducting radio transmission experiments around the English Channel and in 1901, Marconi is credited with sending out the first transatlantic transmission.
