I love stuff like this:
There may be no single invention that shaped the modern city as much as the elevator. But the elevator, of course, is not a single invention. It’s a series of innovations going back hundreds of years and continuing now and into the future. Otis Elevator Company, founded 160 years ago today, quickly became, and remains, one of the largest elevator companies in the world thanks largely to Elisha Otis, who invented the elevator safety brake in the 1850s.
