Tesla was working with electromagnetic fields which is a short step away, if at all, from radio wave propagation. The fact that he didn't use today's accepted terminology does not detract from his accomplishments. Even the patent office did not know those terms! Semantics, pure and simple. Sure, Tesla didn't know what he had discovered/invented and neither did anyone else because it was virgin territory. The operator here is the word "invention" where Tesla didn't know or didn't have the terminology to define/explain the phenomena but neither did anyone else. There are no doubt other "inventions" that would fail the test now as to what was acceptable then even bearing the fact that nobody knew what they had discovered as far as fully and adequately defining it is concerned. Therefore, in retrospect we can conclude that Tesla "invented" radio apart from communication and if anyone wants to be convinced of it, read the books referenced in previous posts. On the other hand, equally inventing was Marconi but what he invented was radio communication. Tesla was more into radio transmission of electrical power and actually experimented with radiation and was equally in the dark as to what he had discovered. Furthermore, he realized that radiation was something he could not understand and stopped all experimentation with radiation because of its potential for damaging the human body. Stubblefield also invented radio but because it was more a matter of electromagnetic fields and not the propagation of radio waves, he is attributed the "invention" of Radio Broadcasting and this is partially because his communications were one-way, not two-way. However, much of what was being done in radio was gauged alongside the telegraph as far as communication was concerned. Bell's telephone was not only able to do two-way communication, it was able to do both sides of the conversation at the same time. This means that the whole communications scene was not so simple, after all. You have to give it to Marconi like that historical piece said: He took what others had done and were doing and he put it all together into a practical and successful method of radio communications. The priest in Brazil and Stubblefield, however, invented systems that used voice communication and this sets them apart from those who merely used coherers, decoherers, inkers and relays to operate other apparatus. Tesla does not take anything away from Marconi. In fact, both discovered ways of using radio but Tesla used it for power transfer and is more famous for phase manipulation while Marconi refined all the then extant technology into a viable communication system. The world has survived both Marconi AND Tesla.
