In 1853, Elisha Graves Otis sold his first safety elevator equipment, having started his business earlier in the year to sell the safety elevator system he had invented the year before. His customer was Benjamin Newhouse in New York City who used it for moving freight. Shortly thereafter, in May 1854, at the Crystal Palace in New York City, Otis created public interest with a daring demonstration. He was hoisted high in the air on a platform fitted with his safety feature. When he called for the rope to be cut, the safety device stopped his fall. By 1857, he installed the first department store passenger elevator at E.V. Haughwout & Co. in New York City. In 1889 he applied the electric motor to power elevators.«

A very successful businessman...

A very successful businessman had a meeting with his new son-in-law. I welcome you into the family,” said the man. “To show you how much we care for you, I am making you a 50-50 partner in my business. All you have to do is go to the factory everyday and learn the operation.”
The son-in-law interrupted. “I hate factories. I can’t stand the noise.” “I see.” replied the father-in-law, “Well, then you’ll work in the office and take charge of some of the operations.” “I hate office work,” said the son-in-law. “I can’t stand being stuck behind a desk.” “Wait a minute,” said the father-in-law. “I just made you half owner of a money-making industry, but you don’t like factories, and won’t work in an office. What am I going to do with you?” “Easy,” said the son-in-law. “Buy me out.”
