On June 21, 1943 the Supreme Court of the United States held the broad claims of Guglielmo Marconi's patent for improvements in apparatus for wireless telegraphy to be invalid. The books don't mention that the powerful spark transmitters used by Marconi were Tesla coils, nor do they point out that Marconi's central radio patents were later struck down because of Tesla's prior art. The Physics was awarded to Marconi for radio in 1909. It was a mistake. As early as 1892, Nikola Tesla created a basic design for radio.
