In Stamps: Who Invented The First Radio?

Who invented the first radio? Alexander Stepanovich Popov, Guglielmo Marconi or Jagadish Chandra Bose? All three men were contemporaries and were aware of the electromagnetic studies by Heinrich Rudolf Hertz, James Clerk Maxwell  and Oliver Lodge, each of whom contributed to the basis of radio communications. But they did not apparently see the value in developing a communication system based on electromagnetic waves. So, if not these men, then who can claim to have 'the first' such apparatus? Well, if based on national pride, then the nation of each man makes the claim -- Russia, Italy (Ireland too, as Marconi was half Irish) and India (Bangladesh, as Bose was a Bengali). However,  in the final analysis, it is the official documentation that awards the inventor the title of being 'the first". That said, the stamps below from Russia, San Marino and India honour each of these radio pioneers/inventors.

RUSSIAN POST in 2015 issued a first day cover stamp marking the invention of radio by Alexander Stepanovich Popov. On 7 May 1895, during a meeting of the Russian Physicochemical Society in St. Petersburg,  Russian scientist-inventor, physicist and electrical engineer Alexander Stepanovich Popov demonstrated the operation of the world's first radio receiver.

The 1895 radio depicted on this stamp is on exhibit at the A.S. Popov Central Museum of Communications named after him. The maxi card is one of only 10 printed and shows the Russian Physicochemical Society meeting when Popov first presented his invention.

SAN MARINO POST in 1995 issued a first day cover stamp marking the 100 anniversary  of the invention of radio by Guglielmo Marconi. This 850 Lira stamp was jointly released not only in San Marino, but also Germany, Ireland and Italy in the same year.   

Now, who invented the radio? There is no simple answer to the question. While the invention of radio seems to have been about the same time -- in the late 1890s -- the claim can be made by not only Popov and Marconi but also Jagadish Chandra Bose. First off, Alexander Stepanovich Popov was a contemporary of Guglielmo Marconi, but the two men developed their radio apparatuses independently and without knowledge of the other’s work. Making a definitive claim of who was first is complicated by inadequate documentation of events, conflicting definitions of what constitutes a radio, and national pride.

One of the reasons why Marconi gets the credit and Popov doesn’t is that Marconi was much more savvy about intellectual property. One of the best ways to preserve your place in history is to secure patents and publish your research findings in a timely way. Popov did neither. He never pursued a patent for his lightning detector, and there is no official record of his 7 May 1895 demonstration. He eventually abandoned radio to turn his attention to the newly discovered Röntgen waves, also known as X-rays.

Marconi, on the other hand, filed for a British patent on 2 June 1896, which became the first application for a patent in radiotelegraphy. He quickly raised capital to commercialise his system, built up a vast industrial enterprise, and went on to be known — outside of Russia — as the inventor of radio.

Lastly, Sir Jagadish Chandra Bose like Popov did not file a patent. In fact, Marconi and he met about the time Marconi demonstrated and patented his radio. Professor Bose however is recognised as the inventor of semiconductors and microwave technology.

INDIA POST AND BANGLADESH POST have both issued commemorative stamps of Bose.

BBC Encompass (via Tinang)

BBC Encompass, transmitting from Tinang, Philippines, was logged on 1 July 2019. English broadcast featured "History Hour" which reported on the Stonewall Gay Rights Movement book by Eric Markus, followed report on Iraqi chemical attack on Kurds by Saddam Hussein's regime, promo for BBC programme "Marching to the Fast Beat", then discussion on Joseph Heller's book "Catch-22," serial murders committed by Fred and Rose West in southern England, and 1969 movement called "Association to Aid Fat People", and lastly Summary of News presented by Gloria Marshall. This was monitored from 23.15 till 00.00 UTC. Reception on 11.825 kHz rated a SINPO of 55444 -- strong signal and clear audio despite slight fading. Station splatter from adjacent frequency degraded signal at 23.59 UTC to 53443. HERE is BBC via Tinang.

Reception report was emailed to Encompass on 12 March 2020. I presume this is verification for the above report, as one of four BBC reception reports were sent to Encompass in 2019 and 2020. QSL card arrived in the mail on 22 June 2021.
