Alexander Popov is a famous Russian physicist and inventor of radio. Popov was born in 1859 in Perm Province. In the family, except for Alexander, grew another six children and lived very modestly Popov. But this did not prevent the boy to make every effort to study and achieve great success in science.
In 1882, Popov successfully graduated from the University and was invited to stay to prepare for his professorship. Alexander dreamed of conducting experiments in the field of electricity, and this was one of the reasons that he began to teach in the officer class of Kronstadt, where there was a modernly equipped physics class. In 1890, he was invited to teach physics at a Technical school in the same city. All his free time from teaching Popov devoted to physical experiments, which resulted in the invention of radio in 1895.
In April 1895, Popov presented a new device to the Russian physico-chemical society and made a report on the invention of wireless communication. He also studied x-rays and took x-rays of various objects for the first time in Russia.
Alexander Stepanovich Popov passed away in 1906. His contribution to Russian science was highly appreciated by the countrymen: his name was given to the museums, streets, schools, awards, companies, etc. are Monuments to the scientist in Saint-Petersburg, Krasnoturinsk, Ekaterinburg and 5 cities. In 1949 the film about his life and scientific activity "Alexander Popov"was shot.
