Nikola Tesla gives the first public demonstration of radio in St. Louis, Missouri.1.3.1893
Wikipedia (06 Mar 2013, 11:12)
In 1893, in St. Louis, Missouri, Serbian-American inventor Nikola Tesla made devices for his experiments with electricity. Addressing the Franklin Institute in Philadelphia and the National Electric Light Association, he described and demonstrated the principles of his wireless work. The descriptions contained all the elements that were later incorporated into radio systems before the development of the vacuum tube. He initially experimented with magnetic receivers, unlike the coherers (detecting devices consisting of tubes filled with iron filings which had been invented by Temistocle Calzecchi-Onesti at Fermo in Italy in 1884) used by Guglielmo Marconi and other early experimenters.
