Editorial
In a recent issue we reprinted some remarks about a court-case in America, dealing with radio patents and more particularly, the part which Marconi played in the invention of radio communication. This article aroused considerable comment, especially from those who are loyal supporters of Marconi. It has been pointed out often enough that wireless waves, as such, were first known as hertzian waves, after Hertz, German scientist who holds credit for their discovery. A correspondent has pointed out, however, that in December, 1889, an engineer, named Huber, wrote to Hertz and suggested the use of his oscillations for communications, but Hertz turned down the idea! Another correspondent points out that the preliminary experiments in the use of hertzian waves for communications were carried out by a Russian named Popov, who demonstrated reception before the Russian Physical-Chemical Society on May 7, 1895. This demonstration was not the mere starting of Popov's experiments, either, as he had lectured on the subject at the Marine Officers' Club in Kronstadt in the spring of 1889. Dealing with the recent interpretation by the Supreme Court in U.S.A., it is still far from clear that the court ruling did anything which could be defined as a contradiction of the generally-held view that Marconi was the father of radio communication. There seems little doubt that Marconi and his organisations reaped the honour, glory and financial reward to which they were rightly entitled.
