Who invented the elevator?
Primitive elevators were in use as early as the 3rd century BC, operated by human, animal, or water wheel power. The first documented evidence of the elevator is found in the works of Vitruvius, the Roman architect. He reported that Archimedesbuilt the first one in about 236.From about the middle of the 19th century, power elevators, often steam-operated, were used for conveying materials in factories, mines, and warehouses. In 1853, American inventor Elisha Otis demonstrated a freight elevator equipped with a safety device to prevent falling in case a supporting cable should break. Otis established a company for manufacturing elevators and patented (1861) a steam elevator. In 1846, Sir William Armstrong introduced the hydraulic crane, and in the early years 1870s, hydraulic machines began to replace the steam-powered elevator.Electric elevators came into to use toward the end of the 19th century.
