wireless telegraphy. These experiments had to do with the Hertz vibrator and resona-
tor described in his first work entitled ‘Concerning Extremely Rapid Electric Oscilla-
tions’.
The scientific value of Hertz’ discovery, however, is not the less though he did
not find a practical application for it. Hertz’ discovery was immediately recognized
throughout the world, and Popov was one of the first to begin elaborating further this
extremely important scientific advancement. He read papers and delivered public lec-
tures, always pointing out that this new achievement of science is not only of theo-
retical value, that it may find a practical application.
May 7 (April 25, old style) 1895 is considered to be the date of the invention of
radio. It was on this day that Popov read a paper in the Physics Department of the
Russian Physical and Chemical Society entitled ‘On the Relation of Metal Powders to
Electric Oscillations’. However, Popov arrived at his discovery much earlier; not at
once, of course, but as a result of extensive research which he had conducted over a
period of several years studying electric waves and oscillations. The May 7

was a legal confirmation of Popov’s right as the inventor of wireless telegraphy.
Popov was undoubtedly an original and experienced experimenter.
But in addition, Popov was the first radio specialist to construct radio instru-
ments as well as radio stations in Russia. This side of his activities was above all
closely connected with the Navy, the most prominent representatives of which valued
Popov especially as a practical specialist in installing radio in the Navy.
In March 1897, he delivered a lecture at the Kronstadt Naval Officers’ Club,
dealing with the possibility of wireless telegraphy through the use of his method.
Popov’s project was well received and was approved by the higher authorities.
The year of 1897 was that of a considerable victory for the inventor of radio,
who began experimenting on a large scale.
The first radiogram was received on the island of Gogland on January 24. It was
an order of the Head of the Chief Naval Staff, Vice-Admiral Avelan, on the rendering
of aid to Finnish fishermen who had been carried out to sea on an ice-floe. It ran as
follows :
‘To the commander of the ice-breaker Yermak’.
‘An ice-floe with 50 fishermen on it broke away near Lavensari. Render imme-
diate aid to save these people’.
The accident was reported by telephone to St. Petersburg, and from there a tele-
gram was sent to Kotka, whence the order was radioed to Gogland. The chief of the
Gogland station, Zalevsky, wrote that the report was received clearly, and was imme-
diately passed on to the ‘Yermak’. At four the next morning the Yermak set out on
the search for the men and returned at 5 o’clock in the afternoon with all of them on
board.
News of the fishermen being saved from imminent death through the use of
wireless telegraphy, which conveyed to the Yermak the message, spread throughout
Russia.
The very next day after the saving of the fishermen Popov was swamped with
telegrams of congratulation expressing pride and admiration for this achievement of
