Who invented the remote control?

Renowned Serbian-American inventor Nikola Tesla created one of the world's first wireless remote controls, which he unveiled at Madison Square Garden in New York City in 1898. He called his fledgling system, which could be used to control a range of mechanical contraptions, a "teleautomaton." For his demonstration, Tesla employed a miniature boat controlled by radio waves. The boat had a small metal antenna that could receive exactly one radio frequency.
