Alexander Stepanovich Popov

Russians celebrate the 7th day of May as their radio day. On May 7, 1895, a Russian navy officer Alexander Popov presented his lightening detector to the Russian Physical and Chemical Society. His device was a radio receiver capable of detecting electromagnetic waves coming from lightening. Thus to Russians, Popov is the inventor of radio communication. They never heard of Marconi or Tesla.

I do not know from where I got the photo of Stalin and Roosevelt, but it is old enough to be in the public domain. The photo of the USS Repose was taken by John Rich during the Korean war (1950-53).
