ElevatorIn 1857, the world's first passenger safety elevator went into service in a store at 488 Broadway and Broome Street in New York City. The safety elevator invented by Elisha Otis was powered by steam through a series of shafts and belts. As the safety and efficiency of the early elevators continued to improve, space in buildings' upper floors soon became more desirable, reversing a long-standing trend in commercial and residential leasing. By 1870, Otis Brothers & Company had revenues in excess of US$1 million. A couple of years later, there were no less than 2,000 Otis elevators in use. |
