Answer: He invented the safety elevator

Elisha Otis invented the first safety elevator. He attached the hoist rope for the elevator to a spring at the top of the elevator and the spring was attached to a a pair of ratchet bars on the sides of the elevator. As long as the spring had tension on it, the ratchet bars were not engaged. But if the rope broke, the tension on the spring was released, allowing the ratchet bars to engage and stop the elevator. During the 1854 New York World's Fair, he had himself hoisted in an open elevator up a couple of stories, and had an axe man cut the hoist rope, showing that his invention would work.
