Following up on Hertz's work, the genius Nikola Tesla first demonstrated wireless communication in 1893. One year later, the Bengali physicist Sir Jagadish C. Bose and the British physicist Sir. Oliver J. Lodge followed suit. Meanwhile, in England, a young Italian named Guglielmo Marconi had been hard at work building a wireless device. Tesla filed the first US radio patent in 1897. Marconi's first patent application in the US, in 1900, was turned down. His revised applications were repeatedly rejected because of the priority of Tesla. Nonetheless, his Marconi Wireless Telegraph Company Ltd. began thriving. Then, on Dec. 12th, 1901, Marconi for the first time transmitted signals across the Atlantic. Tesla commented:
"Marconi is a good fellow. Let him continue. He is using 17 of my patents."
In 1904, surprisingly, the US Patent Office reversed previous decisions and gave Marconi a patent for the invention of radio. Marconi later won the Nobel Prize and Tesla sued his company for infringement. In 1943, a few months after Tesla's death, the US Supreme Court finally overturned Marconi's patent in favor of Tesla.
