It used to be that buildings could only be built to a certain height, and anything higher was impractical.
It wasn't so much the building materials, the scaffolding and equipment needed, or other architectural problems, as it was one simple thing: who wants to try to go up fifty flights of stairs?
Yes, there were hoisting platforms, attached to pulleys, but the ropes often broke, and they were used only during construction, in warehouses or for moving materials. They were not safe enough for passengers.
Then, a genius mechanic and tinkerer came up with what was later recognized as a brilliant idea. He demonstrated it at the 1853 World's Fair in New York. Standing on one of the platforms, he had an axeman cut the rope in front of the amazed crowd. Instead of plunging to his death, they were stunned when the platform went down only a few inches, then stopped.
After this, Elisha Otis received continuous orders for his steam elevators with the safety brake. On this day in 1861 he received a patent for the 3-way steam valve engine that made it possible for his safety elevators to transition from up to down more quickly, and to make fast stops.
City skylines with tall buildings were made possible by Elisha Otis.

One wonders if Mr. Otis could have possibly envisioned what his invention would turn the world into! :)
