Who invented the safety elevator? Correct Answer Elisha Otis

In 1852 Elisha Otis designed and installed what he called the “safety hoist,” the first elevator equipped with an automatic safety device to prevent it from falling if the lifting chain or rope broke. The next year he set up a small elevator shop in Yonkers, selling his first elevator machine on September 20, 1853. It hauled freight. On March 23, 1857, he installed the first safety elevator for passenger service in the store of E.V. Haughwout & Co. in New York City.
