Radio Day
[1]
(
Russian
:
День радио
,
Den' Radio
),
Communications Workers' Day
(as it is officially known in
Russia
) or
Radio and Television Day
(
Bulgarian
:
Ден на радиото и телевизията
, as it is known in
Bulgaria
) is a commemoration of the development of
radio
in Russia. It takes place on 7 May, the day in 1895 on which
Alexander Stepanovich Popov
demonstrated a radio based lightning detector.
Origins
[
edit
]
On 7 May 1895, Alexander Stepanovich Popov presented the paper "On the Relation of Metallic Powders to Electric Oscillations" before the Russian Physical and Chemical Society in St. Petersburg, which described his
radio wave
based device that used Sir
Oliver Lodge's
coherer
as a
lightning
detector.
[2]
Popov's device was just a radio receiver, he would not develop a radio transmitter until over a year later (a year and a half after
Guglielmo Marconi
developed a similar device.
[3]
[4]
Popov's presentation was declared the "
inventor of radio
" in the former
Soviet Union
and Eastern Europe (although historians note it may be more due to
Cold War
era politics than historical evidence).
[5]
The first Radio Day was observed in the Soviet Union in 1945, on the 50th anniversary of Popov's experiment, and some four decades after his death. Radio Day is officially marked in Russia and Bulgaria.
