Alexander Stepanovich Popov Scientist

Alexander Stepanovich Popov (sometimes spelled Popoff; Russian: Алекса́ндр Степа́нович Попо́в; March 16 [O.S. March 4] 1859 – January 13 [O.S. December 31, 1905] 1906) was a Russian physicist who is acclaimed in his homeland and eastern European countries as the inventor of radio.Popov's work as a teacher at a Russian naval school led him to explore high frequency electrical phenomena. On May 7, 1895 he presented a paper on a wireless lightning detector he had built that worked via using a coherer to detect radio noise from lightning strikes. This day is celebrated in the Russian Federation as Radio Day. In a March 24, 1896 demonstration he used radio waves to transmit a message between different campus buildings in St Petersburg. His work was based the work of other physicist such as Oliver Lodge and contemporaneous with the work of radio pioneer Guglielmo Marconi.
