Did you know that first ever 'elevator
pitch' was done in an elevator? And it was about - elevators? Elevator
brakes, to be more precise.
In the year 1853, Elisha Graves Otis
invented a system that would automatically halt an elevator if the
hoisting rope snapped. The sales didn't go as Elisha expected, so he
decided to publicly demonstrate his invention at the exhibition at the
New York Crystal Palace in 1854. An elevator was installed, and while he
was in it, Elisha asked his assistant to cut the hoisting rope.
Demonstration was successful and demand for safe elevators began to
rise.
