Alexander Miles?

Answer

Alexander Miles was an American inventor. His best known invention was the automatic open and closing doors designed for an elevator. The invention that made him famous was patented by him in 1887. There was much controversy surrounding his patent acceptance as several years earlier in 1874, a man named John W. Meaker, had patented the same exact idea. Prior to both inventions, elevator doors had to be manually closed and opened. Modern day elevators use the design created by Alexander Miles.
