Alexander Stepanovich Popov, born 1859 was a Russian physicist who was the first person to demonstrate the practical application of electromagnetic radio waves.

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. Alexander received a good education at the seminary at Perm, and later studied physics at the St. Petersburg university. After graduation in 1882 he started to work as a laboratory assistant at the university. However, due to the poor funding of the university he changed to a teaching job at the Russian Navy's Torpedo School in Kronstadt on Kotlin Island.

Beginning in the early 1890s he conducted experiments along the lines of Heinrich Hertz's research. In 1894 he built his first radio receiver, which contained a coherer. It was presented to the Russian Physical and Chemical Society on May 7, 1895- the day has been celebrated in the Russian Federation as "Radio Day". The paper on his findings was published the same year (December 15, 1895). He did not apply for a patent for his invention. In 1896, the article depicting Popov's invention was reprinted in the 'Journal of the Russian Physical and Chemical Society'. In March 1896, he effected transmission of radio waves between different campus buildings in St. Petersburg. In November 1897, the French entrepreneur Eugene Ducretet made a transmitter and receiver based on wireless telegraphy in his own laboratory. According to Ducretet, he built his devices using Popov's lightning detector as a model. By 1898 Ducretet was manufacturing equipment of wireless telegraphy based on Popov's instructions. At the same time Popov effected ship-to-shore communication over a distance of 6 miles in 1898 and 30 miles in 1899.

On December 18, 1897, Popov sent the telegram with the words "Heinrich Hertz".

In 1900 a radio station was established under Popov's instructions on Hogland island to provide two-way communication by wireless telegraphy between the Russian naval base and the crew of the battleship General-Admiral Apraksin. The battleship ran aground on Hogland island in the Gulf of Finland in November, 1899. The crew of the Apraksin were not in immediate danger, but the water in the Gulf began to freeze.

Due to bad weather and bureaucratic red tape, the crew of Apraksin did not arrive until January 1900 to establish a wireless station on Hogland Island. By February 5, however, messages were being received reliably. The wireless messages were relayed to Hogland Island by a station some 25 miles away at Kymi (nowadays Kotka) on the Finnish coast. Kotka was selected as the location for the wireless relay station because it was the point closest to Hogland Island served by telegraph wires connected to Russian naval headquarters.

By the time the Apraksin was freed from the rocks by the icebreaker Yermak at the end of April, 440 official telegraph messages had been handled by the Hogland Island wireless station. Besides the rescue of the Apraksin's crew, more than 50 Finnish fishermen, who were stranded on a piece of drift ice in the Gulf of Finland, were saved by the icebreaker Yermak following distress telegrams sent by wireless telegraphy. In 1900, Popov stated (in front of the Congress of Russian Electrical Engineers) the emission and reception of signals by means of electric oscillations.

In 1901 Alexander Popov was appointed as professor at the Electrotechnical Institute, which now bears his name. In 1905 he was elected director of the institute.

In 1905 he became seriously ill, after being very stressed about the suppression of a student movement. He died of a brain hemorrhage on January 13, 1906.
