Later, with the aid of sensitive telephone headphones, the reception range was extended to five kilometers.<\/p>\n<p>In 1900 the first radio stations of Popov\u2019s system appeared on ships of the Russian fleet, and the range of communication reached 150 km. In the Soviet Union the professional holiday known as \u201cRadio Day\u201d was celebrated every year on 7 May.<\/p>\n<p>Meanwhile, in the West, the inventors of the radio are considered to be the Serbian-American <a href=\"https:\/\/www.britannica.com\/biography\/Nikola-Tesla\">Nikola Tesla<\/a>, who apparently received radio signals from Mars, and the Italian <a href=\"https:\/\/www.britannica.com\/biography\/Guglielmo-Marconi\">Guglielmo Marconi<\/a>, Marquis of Marconi, who founded the first radio engineering company in Great Britain. In 1901 Marconi was able to transmit a signal across the Atlantic Ocean for the first time, and in 1909 he was awarded the <a href=\"https:\/\/www.nobelprize.org\/prizes\/physics\/1909\/marconi\/biographical\/\">Nobel Prize<\/a>.<\/p>\n<p>A milestone in the development of electronics was the year 1906, when radio tubes, which became the foundation of radio equipment for a long period of time, were invented. Almost simultaneously a crystal detector was patented, which made it possible to separate the signal from the carrier radio frequency, the first semiconductors that subsequently replaced radio tubes.<\/p>\n<p>That same year live music, the reading of poems, and a short conversation were broadcast. This was the first attempt at radio broadcasting, with its two main components: information and entertainment.<\/p>\n<p>It was only radio operators at naval radio stations who accidentally picked up the voices and music through their headphones, which were heard amidst the usual squeaking of the Morse code. Mass production of inexpensive receivers began only a few years later.<\/p>\n<p><strong><span style=\"color: #0861a6;\">Down Music Lane<\/span> <\/strong><\/p>\n<p>On 25 January 1884 the future talented scientist, engineer, and entrepreneur who became one of the world\u2019s top creators of radio technology was born into the family of a Kyivan merchant of the First Guild. Eventually, our countryman, Sem\u00e9n Moiseiovych Aizenshtein, Chevalier of the French <a href=\"https:\/\/www.legiondhonneur.fr\/en\/page\/mission-legion-honor\/392\">Legion of Honor<\/a>, achieved recognition and respect in many countries.<\/p>\n<p>However, it is fruitless to look for information about him in encyclopedias and dictionaries published during the Soviet period, because he immigrated to the West in 1922, together with a number of other prominent figures. In his homeland, his name was consigned to oblivion despite the fact that after Popov\u2019s death in 1906, he became his spiritual successor and the most prominent national figure in the field of radio engineering.<\/p>\n<p>He also founded the St. Petersburg-based Society of Wireless Telegraphs and Telephones, the starting-point of the history of the famous <a href=\"http:\/\/www.rusarmyexpo.com\/army2019\/catalog_exhibitors\/members\/32361\">Vektor Scientific Research Institute<\/a> and was also the developer and designer of most of the electronic structures in Russia in the years 1907\u20131922.<\/p>\n<p>The Aizenshtein family settled in Kyiv\u2019s famous cultural center, Muzychny provulok (Music Lane), most likely in a large apartment building built around 1900 by <a href=\"https:\/\/en.wikipedia.org\/wiki\/W\u0142adys\u0142aw_Horodecki\">W\u0142adys\u0142aw Horodecki<\/a>, on the corner of Prorizna Street and Khreshchatyk Boulevard. The telegraph and telephone station was next door, and the young man\u2019s attention was undoubtedly attracted by both the telegraph operators and the young ladies working the telephone switchboard.<\/p>\n<p>After enrolling at St. Volodymyr Kyiv University, Aizenshtein became fascinated with Popov\u2019s work in the field of wireless telegraphy. At home, he set up an experimental radio station consisting of a spark-gap transmitter and receiver and carried out the first radio communication sessions in Kyiv.<\/p>\n<p>In 1901 he spent time in Moscow, visiting the Polytechnical Museum and attending the 2<sup>nd<\/sup> All-Russian Electrotechnical Congress. There, the 17-year-old Kyivan student was introduced to Popov, who was amazed by the breadth of his scientific views and creative approach.<\/p>\n<p>This encounter inspired Aizenshtein, and soon afterwards he obtained his first patent. Thanks to his abilities and financial support from his father, after graduating from Kyiv University, he continued his studies at the University of Berlin and the Technische Hochschule Charlottenburg. After returning to Kyiv, in 1905 he set up a wireless telegraphy laboratory.<\/p>\n[Vladimir] <a href=\"https:\/\/en.wikipedia.org\/wiki\/Vladimir_Sukhomlinov\">Sukhomlinov<\/a>, the Governor General of Kyiv and future Minister of War of Russia (1909\u20131915), became interested in these experiments, and acquired funding for them from the Military Department, as well as land allocated in Kyiv and Zhmerynka for the construction of powerful experimental radio installations.<\/p>\n<figure id=\"attachment_15751\" aria-describedby=\"caption-attachment-15751\" style=\"width: 450px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/ukrainianjewishencounter.org\/media\/21IstPravda_03.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-15751\" src=\"https:\/\/ukrainianjewishencounter.org\/media\/21IstPravda_03.jpg\" alt=\"\" width=\"450\" height=\"643\" srcset=\"https:\/\/ukrainianjewishencounter.org\/media\/21IstPravda_03.jpg 450w, https:\/\/ukrainianjewishencounter.org\/media\/21IstPravda_03-350x500.jpg 350w\" sizes=\"auto, (max-width: 450px) 100vw, 450px\" \/><\/a><figcaption id=\"caption-attachment-15751\" class=\"wp-caption-text\">Aizenshtein\u2019s wireless telegraph station in Kyiv<\/figcaption><\/figure>\n<p>Meanwhile, Aizenshtein was already testing mobile field radio stations. His next patent attested to the pioneering nature of his work. The newspaper <em>Kievskaia mysl<\/em> [Kyivan Thought] wrote on 23 (10) February 1907:<em>\u00a0<\/em><\/p>\n<p>\u201cOn February 1 and 2 the Kyiv wireless telegraph station transmitted telegrams to Odesa over a distance of 410 <a href=\"https:\/\/www.merriam-webster.com\/dictionary\/verst\">versts<\/a>. The signal strength showed that this is still not the maximum distance at which the station can transmit its signals.<\/p>\n<p>The Kyiv station can transmit telegrams over a distance of about seven hundred versts by land, which corresponds to the distance by sea of around two thousand versts. The station was built by S. M. Aizenshtein in order to test the proposed system. During experiments in Odesa we managed to receive simultaneous telegrams from Kyiv and Zhmerynka, where there is also a station built according to S. M. Aizenshtein\u2019s system.<\/p>\n<p>The Odesa station, built for communicating with Sevastopol (a distance of about three hundred versts by sea), could not respond to the Kyiv telegram, owing to the weak devices.

In his speech, the professor of physics Georgy De Metz declared in the name of the Kyiv branch of the Imperial Russian Technical Society: \u201cAfter the capitals of Moscow and [St.] Petersburg, the first provincial city in which the congress is conducting its activities is Kyiv. It is precisely here that electricity acquired the broad rights of citizenship: Alternating current lights streets and buildings; direct current transports [us] by the urban train [as the streetcar was known at the time\u2014V.L.].<\/p>\n<p>We have a substantial telephone network; plumbing works with the aid of electricity. We have a wireless telegraph station, which communicates over a distance of 230 versts with Zhmerynka, and over 410 versts with Odesa. In addition, the first state-owned telephone network with a station, the largest of the state installations in the empire, has been installed in Kyiv. And much more needs to be done to improve human existence.\u201d<\/p>\n<p>In the evening, the Kyiv municipal government held a reception for the participants of the congress in the hall of the Municipal Duma.

France awarded Aizenshtein the medal of the Legion of Honor and granted him the status of a French subject.<\/p>\n<p>For signals intelligence, the production of radio direction finders, which helped determine the location of enemy headquarters, was set up in 1916; this was the beginning of electronic warfare.<\/p>\n<p>By the middle of the war the army and the navy, up to the company level, already had radio communication devices, thanks in no small part to Aizenshtein.

Aizenshtein had no choice but to curb his creative entrepreneurial nature and focus on scientific work.<\/p>\n<p>In 1918 a government meeting took place at the Nizhny Novgorod laboratory, during which Aizenshtein was appointed scientific specialist at the Higher Radio Engineering Council responsible for setting up a radio network in the Soviet republic, particularly communications between Moscow and Vladivostok.<\/p>\n<p>Delivering numerous reports and publishing articles in radio magazines, Aizenshtein did much to promote radio. In 1920 the first Soviet broadcasting station went out on the air in Nizhny Novgorod. Soon there was a second one, in Moscow, using twelve kW of power, and its signal was received even in Germany.<\/p>\n<p>In 1924 the first Ukrainian broadcasting station was launched in Kharkiv.

Since he had French citizenship, in the early 1920s Aizenshtein decided to immigrate to Great Britain, to his former friend and ROBTiT colleague, Marconi. He left illegally via Riga.<\/p>\n<p>Later, Aizenshtein oversaw the construction of radio engineering plants in Poland (1922\u20131935) and Czechoslovakia. During the Second World War, he worked in Great Britain, at the electro-vacuum laboratory of the Marconi Company. After the war, he founded his own firm, the <a href=\"https:\/\/www.radiomuseum.org\/dsp_hersteller_detail.cfm?Company_Id=8417\">English Electric Valve Company Limited<\/a>, which he headed until 1955 when he retired.
