On This Day in Inventor History – February 20 February 20, 1872 – The Patent for the Electric Elevator is Granted On this day in 1872, Alexander Miles was granted a U.S. patent for his groundbreaking improvements to automatic elevator doors! Before his invention, elevator doors had to be manually opened and closed—a dangerous flaw that often led to accidents. Miles’ innovation introduced self-closing elevator doors, making vertical transportation safer and more reliable. His work laid the foundation for the modern elevator systems we use today. Elevators transformed urban architecture, enabling the rise of skyscrapers and revolutionizing how people move within buildings. Imagine a world without elevators—how different would our cities look?
