Russian born, US aeronautical engineer, Igor Sikorsky (1889-1972), designed and flew the first four engined aircraft in 1913 and designed the first successful helicopter in 1939. As to why, I can only guess that he saw a need and fulfilled it, or somebody asked him, or he picked up on one of Leonardo da vinci's ideas.
