The Invention of the Radio

1.	On April, 25, 1895, A.S. Popov demonstrated his device. Having summarized the results of his experiments, Popov expressed his hope that the device, after being perfected, would make possible transmitting signals at a distance by means of rapid electrical oscillations. In summer 1895, Popov’s invention was successfully tested and in the same year he attached to the device an apparatus previously used for recording telegrams. In the following year this receiver was used at the electric power station in Nizhy Novgorod for warning about approaching thunderstorms.
2.	The great Russian inventor did not make any secret of his discovery, describing it in the press and making reports about it at the meetings of scientific societies. In the same year he demonstrated the transmission of words over a wireless telegraph. This new demonstration proved of great importance as later on, in England, there appeared a person, Marconi by name, who claimed to be the inventor of this new means of communication.
3.	The year 1898witnessed a new important invention made by Popov together with his assistants Rybkin and Troitsky, namely the reception of audible signals by means of a receiver. All these successful experiments having been completed, serious practical testing began. Popov’s radio telegraph helped to save the battleship “General Admiral Apraksin”.
	Popov’s work drew attention of many countries. The wireless telegraphy is the result of Popov’s experiments, this fact having been acknowledged by different representatives of foreign science, engineering and industry. Popov was offered immense profits from commercial side of his invention in case he leaves Russia, but he preferred to remain a true son of his fatherland. “I am a Russian and I must give all my knowledge, all my work and all my achievements to my native land”, were his words.
	It is impossible to say that nobody in Russia understood and appreciated the great work carried out by Popov. On the contrary, the leading representatives of Russian science realized the significance of his invention. However, the tsarist government did nothing to provide the training of specialists for the newly born branch of science and engineering. Neither was home production of devices for wireless telegraphy organized in Russia. Instead it was handed over to foreign companies. By 1914, the beginning of the first imperialistic war, the results of Popov work had been concentrated in foreign hands. Even the supply of the Russian army with radio devices depended upon a German concern in Berlin.
