欧提司 (Otis) 开始了电梯工业
1853年9月20日
欧提司决定要作一个公开的展示。他爬上他架设在纽约「水晶宫」 (Crystal
Palace) 的电梯上方，当电梯升到最高点时，他下令断开缆绳。当人们看到欧提司的安全煞车系统让电梯不会往下掉的时候，才瞭解他的发明是很重要的。虽然到了1856年，欧提司总共只架设了27部电梯，但是他的成就却开启了载客电梯的工业。全世界第一部安全载客电梯在1857年被安装在纽约的一家商店里，以每分钟40英尺的速度上升。和现在的电梯相比，你觉得有什么不同呢？
Otis staged a public demonstration. He climbed on top of his elevator in New York's Crystal Palace exhibition, and while hoisted to the ceiling, ordered the rope cut. Seeing how his safety brake kept him from falling, people realized the importance of his invention. Though in 1856, Otis's sales totaled just 27 elevators, his performance launched the passenger elevator industry. The world's first safety elevator for passengers, installed in 1857 in a New York store, rose at a speed of 40 feet per minute. How does that compare to today's elevators?
