Profile America — Sunday, March 23rd. The ingenuity of one man helped to change the very shape of America's cities — and indeed, those around the world. On this date in 1857 in New York City, Elisha Otis installed the first passenger safety elevator. His invention meant that riders were safe, even if the hoisting cable of an elevator broke. Within a short time, architects began to design increasingly taller buildings. And reversing centuries of practice, the elevator made the upper floors of a building more desirable for owners and renters than the lower ones. Making and installing elevators and escalators is a nearly $2.5 billion a year business for some 190 establishments in the U.S., providing jobs for more than 9,500 people.
