Escalators, in the form people would recognize today, emerged in the late 19th century, with the first working “inclined elevator” by Jesse Reno patented in 1892 and installed as a ride in the 1890s, and the first truly commercial flat-step escalator appearing in 1899.

Quick scoop

  • The first patent-like idea for moving stairs dates to 1859, when Nathan Ames received a U.S. patent for “Revolving Stairs,” but it was never actually built or put into operation.
  • The first working escalator is credited to Jesse Wilford Reno, who patented an “Endless Conveyor or Elevator” on March 15, 1892, calling it an inclined elevator rather than “escalator.”
  • Reno’s moving incline was installed as a short ride on a pier at Coney Island, New York, in the mid‑1890s and is widely cited as the first practical, operating escalator system.

From patents to real machines

  • After Reno’s success, Charles Seeberger took George Wheeler’s flat-step moving stairway concept, refined it, and partnered with Otis Elevator Company to build a new style of moving staircase.
  • In 1899, Otis built Seeberger’s design into what is often called the first commercial escalator , with flat steps driven by a continuous chain and terminals using comb plates to make boarding and exiting safer.

When did “escalators” become common?

  • The word “escalator” itself was popularized when Seeberger named his moving staircase design in 1899, and Otis later acquired both his patents and the rights to the term in 1910, cementing the name in public use.
  • By the early 20th century, department stores, subway systems, and big public buildings were installing escalators, helping turn them from novelty rides into everyday urban infrastructure.

TL;DR:

  • First idea for moving stairs: 1859 (Nathan Ames, never built).
  • First working escalator: Jesse Reno’s inclined elevator, patented 1892 and installed in the 1890s.
  • First commercial flat-step escalator: Otis/Seeberger model, 1899.
