By 1852, Otis had already devised several inventions, including a safety brake for trains. While setting up a factory that year, he developed an automatic safety device to prevent heavy machinery from falling if a rope broke while the machinery was being hoisted.

What daring publicity stunt helped launch sales of Otis’s elevators?
