The Patent Office made the following comment in 1903:
Many of the claims are not patentable over Tesla patent numbers 645,576 and 649,621, of record, the amendment to overcome said references as well as Marconi’s pretended ignorance of the nature of a “Tesla oscillator” being little short of absurd… the term “Tesla oscillator” has become a household word on both continents [Europe and North America].
Although this real-life scientist died before the transistor was invented, Tesla used his formidable mind as we use computers today, designing and testing inventions using only his imagination. Tesla’s intelligence was sharpened by intense powers of concentration, which both blessed and tortured him. Tesla appears to have suffered from symptoms of obsessive-compulsive disorder. His obsessions included phobias of dirt and germs, and of the number three. Tesla’s compulsions included doing everything in sets of three. He worked in solitude, as interacting with ordinary humans was difficult. Perhaps this explains why, in his later years, Tesla claimed to have contacted beings from the planet Venus.
