The first elevator shaft was put in a building before Elisha Otis designed his safe, steam powered elevator. This was done in 1853 at the Cooper Union Foundation building in New York.
When was the first elevator built?
As early as 236 BC, the ancient Greek mathematician, Archimedes built the first known elevator. The achievement is recorded in the works of Vitruvius, a Roman author and architect who lived more than 150 years later.
What did the first elevator do?
The first hydraulic elevators were designed using water pressure as the source of power. They were used for conveying materials in factories, warehouses and mines. Hydraulic elevators were often used in European factories. In 1852, Elisha Graves Otis introduced the first safety contrivance for elevators.
