Over a hundred years there is an argument in the world concerning real radio inventor. But one needs to do a little research to make it clear that Marconi had simply read Popov’s papers. The first known evidence for Marconi to be the radio inventor appeared on June 2, 1896 with his patent application to the UK Patent Office for a discovery, 13 months after Popov had delivered his lecture on radio themes
before the Russian Physical and Chemical Society members in St. Petersburg on May 7, 1895. That secret patent application #12039, inspired as they say by the UK Patent Office’s Principal examiner William Preece, the Chief Electrical Engineer of the British Post Office, however contained no diagrams and charts performed by Marconi himself but his lyrical sketches only.
