Which inventor developed a safe elevator?

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.

What did Elisha Otis invent?
Elisha Otis is known for building the first modern passenger elevator which used his invention of a safety device which prevented the car from falling if the cables broke. The elevator safety brake was first demonstrated at the Crystal Palace Exposition in New York in 1854. After ascending in his new elevator, Otis called for the elevator's cable to be cut with an axe. Instead of falling, the elevator platform held, secured by a brake using toothed guiderails in the elevator shaft and a spring-loaded bar that automatically caught in the toothed rail of the elevator car if the cable failed. Today, the Otis Elevator Company is the world's largest company in the manufacture and service of elevators, escalators, moving walks and people-moving equipment.
Elisha G Otis?
In the mid-1850s elevators were too dangerous to be used for anything but freight. If the rope snapped, a rider would certainly risk life and limb. It was this problem that Elisha G. Otis solved in 1854. Otis had a knack for things mechanical. By age fifteen, he was already an engineer at a bedstead factory. In 1852 Otis was sent to Yonkers to supervise the construction of a new factory, and it was there that he developed several new enhancements to the elevators as they were being designed and installed. Otis' elevators were equipped with a simple spring device that would trigger if the cable broke and prevent the elevator from falling. The invention was patented, and Scientific American called the device "excellent." Otis built a similar elevator at another factory, and while he was installing that one, he received a request for another. Otis was encouraged by the interest in his elevator and formed the E. G. Otis Company in 1853. Then, orders virtually stopped. Companies were simply unwilling to build an elevator for public use. To address this fear, Otis decided to prove his safety device's usefulness by building an elevator and demonstrating it to the crowds at a New York fair. Although he was successful, orders still came slowly. It was not until 1857 that Otis finally built his first elevator specifically for passenger use. Although he died in 1861, Otis's sons took the company into prosperity, and by the turn of the century, Otis elevators were a key element in the appearance of skyscrapers.
