In 1818, seven-year-old Elisha was fascinated by farm machinery. As a
young man, he tried a variety of ways to make a living, but nothing
fired his imagination more than the job he found in a bed-frame factory.
Soon he invented a machine that made frames four times faster than ever
before. In 1852, while overseeing the construction of a new factory, he
had to find a way to move heavy machinery to the second floor. He didn't
trust the hoisting platform, so he invented a safety brake. It was so
successful that rather than lift machine parts, Elisha decided to build
"people-hoisting machines." In 1857, Elisha Otis installed his first
successful passenger elevator in a five-storey department store in New
York City. Before Elisha's invention, buildings were never higher than
six stories. At last it was possible to build skyscrapers!
