Alexander Stepanovich Popov
Alexander Stepanovich Popov (sometimes spelled Popoff; (ロシア語:Алекса́ндр Степа́нович Попо́в); – ) was a Russian physicist who is acclaimed in his homeland and eastern European countries as the inventor of radio.〔 declassified 8 January 2008 〕
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 on the work of other physicists such as Oliver Lodge and contemporaneous with the work of radio pioneer Guglielmo Marconi.
==Early life==
Born in the town Krasnoturinsk, Sverdlovsk Oblast in the Urals as the son of a priest, he became interested in natural sciences when he was a child. His father wanted Alexander to join the priesthood and sent him to the Seminary School at Yekaterinburg.〔 There he developed an interest in science and mathematics and instead of going on to Theology School in 1877 he enrolled at St. Petersburg university where he studied physics.〔〔 A picture of Popov's receiver appears on p. 207, fig. 12.2〕 After graduation with honors in 1882 he stayed on as a laboratory assistant at the university. However the salary at the university was inadequate to support his family, and in 1883 he took a post as teacher and head of laboratory at the Russian Navy's Torpedo School in Kronstadt on Kotlin Island.〔
