The development of the helicopter took place at many places simultaneously, and many helicopters flew before Paul E Williams was born. African-American Paul E Williams was involved in the development of the "first useful helicopter" in particular the Lockheed Model 186 (XH-51). However this helicopter was not produced until 1962. He invented improvements to helicopter design, he didn't invent the helicopter. See the related questions for links to his aircraft.
