Marconi-Radio 

*Guglielmo Marconi was a young boy only 20 years old when Thomas Commorford Martin (Tesla’s first biographer) published Tesla’s discoveries in a book titled, The Inventions, Researches, and Writings of Nikola Tesla, 1894.  The book described (in exact detail) the fundamentals of radio circuitry and its transmission of electromagnetic waves wirelessly.  Later, and long before Marconi or anyone else, Tesla secured his discoveries with the US Patent Office.  

*Having a profound interest in Tesla’s research, Marconi, coming from a family of wealth, was able to afford experiments of his own, but he no doubt utilized the information readily available from Tesla’s published works.

*Tesla had made his focus the wireless transmission of POWER (a lot of it), whereas the wireless transmission of energy for communication purposes (later known as RADIO) was of secondary importance to him, nevertheless still very important.  Marconi, on the other hand, sought only to use wireless transmission of energy for communication purposes.

*Eventually Marconi was successful in transmitting a communication signal across the Atlantic Ocean between Cornwall, England and Newfoundland (December 12, 1901).  But in doing so he incorporated 17 of Tesla’s basic US patents on wireless energy transmission.  This was a feat Tesla had already accomplished, albeit on a smaller scale than a transatlantic transmission, which of course attracted the media’s attention in a huge way.

*Tesla brought his case to the courts, but he lacked the funds to fight it, whereas Marconi was awash with money.  The case was finally resolved in Tesla’s favor by the US Supreme Court on June 21, 1943 (six years after Marconi’s death and six months after Tesla’s death). 

*Marconi is still hailed as the inventor of radio -- so the myth continues.
