Igor Sikorsky was one of many helicopter inventors. He was the one who invented a helicopter that used a tail rotor to counteract the thrust of the main rotor, and he was able to build one with a strong enough engine, an efficient enough rotor, and a light enough airframe. So his helicopter became the first successful commercially produced helicopter.
