Long uncredited creator of many props used on Star Trek and other TV shows as well as several big movies.
First half of the video is on his role in creating many famous Star Trek props while the second half is on his life and his work in movies and his fight with racism and polio.
Of particular note is his fight with Hollywood unions who at first complained about him working on the Star Trek set because he was not a member of the union then them refusing his application because he was "too skilled"
Also note how his name was left off both the called out list of names at the Oscars and off the Oscar itself the effects team he was on won for The Time Machine.
