The invention that built the modern city.

- Otis dramatically proved his invention at the 1854 New York Crystal Palace by standing on an elevator platform high in the air and having an assistant cut the only rope holding him up.
- Before this invention, buildings were rarely taller than 5 stories because people refused to climb that many stairs. The top floors were the cheapest, worst apartments.
- By making vertical transportation safe, Otis birthed the skyscraper, fundamentally creating the high-density urban city centers we know today (and making penthouses the most expensive real estate).
