Tesla’s supporters have often incorrectly interpreted this verdict as an official acknowledgement of the Serbian scientist's priority in the invention of the radio. It should be highlighted that the supreme court was not called upon to give a decision regarding the paternity of the radio invention and the judges never put in doubt the primacy and the originality of the first complete radio system built by Marconi. Indeed, the supreme court’s verdict stated “[…]Marconi's reputation as the man who first achieved successful radio transmission rests on his original patent” and “[..] To find in 1943 that what Marconi did really did not promote the progress of science because it had been anticipated is more than a mirage of hindsight”. Furthermore, Tesla’s wireless apparatus (which was never realized) was an unworkable system as can be deduced by its description: ”[…]since his idea was to make the ether a conductor for long distances by using extremely high voltage, 20, 000,000 to 30,000,000 volts, and extremely high altitudes, 30,000 to 40, 000 feet or more, to secure transmission from aerial to aerial. Balloons, with wires attached reaching to the ground” and lacked the basic theoretical and technical solutions present, instead, in the Marconi plant layout, to allow long distance radio transmission. Indeed, in the Marconi apparatus it was not about to generate, as in the Tesla experience, high level voltages at high frequency with the presence of micro-current but alternating voltages at a set frequency and polarization with significant current levels. Furthermore, in the Tesla's system the primary winding was made up of a few turn of a tick winding while the secondary was composed of millions of rounds of a thin winding. With the Marconi apparatus, the primary was realized by adopting the right number of turns to establish the right wave length of the condenser, and the secondary was made up of a few turns in order to be tuned with the radiation resistance of the antenna. Without all these expedients the low antenna's efficiency would have been too low to allow any long distance communication. In addition, only with the Marconi's system could the vertical antenna change wave lengths by just adding inductances and only his receiver could be switched into transmitter and viceversa (it could work in duplex). Economic, political and military interests have been the main reasons for hostility against Marconi. It’s worth remembering that Marconi was considered an outsider. He didn’t have the support of multinationals or academic institutions, he didn’t pursue a regular graduate education and he was only in his early 20’s when he developed the idea. Despite all this, the most prominent figures in the field of radio transmission at the time such as Pupin, Steinmetz and Preece had always enthusiastically hailed Marconi as the inventor of the radio. This scientific legitimacy was confirmed by the success of his radio system which proved to be the only technology capable of transmitting long distance radio signals making possible a revolution in global communication.
