Biography
Otis was born on August 3, 1811, in Halifax, Vermont, to Stephen Otis and Phoebe Glynn.<ref name="Invent.org Article"/><ref name=":0">Template:Cite web</ref> He moved away from home at the age of 19, eventually settling in Troy, New York, where he lived for five years employed as a wagon driver. In 1834, he married Susan A. Houghton. They had two children, Charles and Norton. Later that year, Otis suffered a terrible case of pneumonia which nearly killed him, but he earned enough money to move his wife and three-year-old son to the Vermont Hills on the Green River. He designed and built his own gristmill, but did not earn enough money from it, so he converted it into a sawmill, yet still did not attract customers. Now having a second son, Otis started building wagons and carriages, at which he was fairly skilled. His wife later died, leaving him with two sons, one age eight and the other in infancy.
In 1845, Otis moved to Albany, New York, where he worked as a master mechanic in a bedstead factory. During this period, he invented a railway safety brake. By 1852, he had moved to Yonkers, New York to work at the Maize & Burns bedstead factory installing machinery.<ref name=":0" /> The factory needed a hoist to lift heavy equipment to the upper floor, but this posed serious safety issues. In response, Otis invented the safety elevator, which automatically comes to a halt if the hoisting rope breaks. The following year, he left the factory and started his own company, the Otis Elevator Company.<ref name=":1" /> After giving a public demonstration of his new invention at the New York Crystal Palace in 1854, demand for the safety elevator began to rise.<ref name=":1" /> He installed the first safety elevator for passenger service at the E. V. Haughwout Building in New York City in 1857.<ref name="Encyclopædia Britannica Article on Elisha Otis">Template:Cite encyclopedia</ref><ref name="Invent.org Article"/><ref name=":0" />
In his spare time, Otis designed and experimented with his old designs of bread-baking ovens and train brakes, and patented a steam plow in 1857, a rotary oven in 1858, and, with Charles, the oscillating steam engine in 1860. The plow was not commercially successful.<ref name=Burton38>Template:Cite book </ref>
Otis contracted diphtheria and died on April 8, 1861; he was only 49 years old.<ref name="Invent.org Article"/> He was buried in Oakland Cemetery in Yonkers, New York.
Legacy
An Otis Elevator Company worker coined the term "escalator" to refer to continuous-loop moving staircases that could either ascend or descend. The company was acquired by United Technologies in 1976. In April 2020, Otis Elevators Company was spun off from United technology to be an independent elevator company.<ref name=":0" />
The World War II U.S. Liberty ship SS Elisha Graves Otis was named after him.<ref>Template:Cite web</ref>
