 In 1853, Elisha Graves Otis demonstrated his Safety Elevator at the New York Crystal Palace exhibition.  He had himself hoisted up on the platform, in full view of alarmed spectators and delighted journalists, and promptly cut the suspension cord.  Nothing happened; the rack and pinion safety lock had worked and he pronounced to the crowd....(Click button to scroll in quote)

“All Safe, Gentlemen”

The first passenger elevator was installed in E.V. Haughwout and Co.’s store on Broadway in 1857.

One could argue that the invention of this simple safety device gave birth to modern day skyscrapers.
