Marshall Elevator is the oldest elevator company in the United States. It was founded in 1818 by John Marshall. Marshall & Son originally was a Blacksmith, but in the 1840s, they started to produce elevators of all kinds. In 1942, they began to sell elevator products by ThyssenKrupp Elevator, which, at the time, was known as Dover Elevator Systems.
After 193 years and seven generations, the family that owned Marshall Elevator sold the company to Otis Elevator Company. The terms of the acquisition were not disclosed.
