September 20, 2023, marked 170 years of business for Otis Elevator Company, commemorating the first sale of an elevator with Elisha Otis' safety brake.
The invention sparked a new industry that made elevators safe and spurred new ways for cities to grow and for people to move.
In this timeline, you'll find many interesting milestones that helped Otis Elevator Company become the world's leading elevator and escalator manufacturing, installation and service company.
Otis can now be found nearly everywhere people are on the move.
1850s
In the beginning: 'all safe'

1853
Company founder Elisha Graves Otis, a skilled craftsman and determined entrepreneur, sells his first elevator following his invention of the elevator safety brake.
It’s an inspired solution to a universal problem of the industrial age – how to safely move freight from floor to floor without risking lives or destroying cargo if the hoisting rope breaks.
His invention ultimately gives rise to the modern city and changes how we live, how cities are built and how the world moves.

1854
To spark sales, Elisha Otis arranges with the showman P.T. Barnum to exhibit his invention in New York during the Exhibition of the Industry of All Nations, commonly known as the Crystal Palace Exhibition. Standing high above the crowd on a platform lift, Otis orders the retaining rope to be cut. The platform drops a few inches and the crowd screams. But the safety brake immediately halts the descent. “All safe, gentlemen, all safe," Otis assures them.
1854-1857
The company sells eight elevators in 1854 and 15 in 1855. In 1857, Otis installs its first passenger elevator in New York City’s E.V. Haughwout Building, a five-story department store whose wealthy clients include Mary Todd Lincoln.
1860s
Securing a patent, building next-generation leaders
1861: Elisha Otis secures a patent in January 1861 to protect his invention. He dies four months later at age 49 in Yonkers, New York, during a diphtheria epidemic. Fortunately, thanks to mentoring from their father, Charles and Norton Otis are ready to take over the business. By the end of the decade the company is thriving, thanks to product innovation and aggressive marketing.
1860s
Securing a patent, building next-generation leaders
1861: Charles Otis pens the first service agreement, where he promises to personally “assume the entire charge and responsibility” for maintaining a steam-powered elevator at a cost of $780 per year.
1860s
Securing a patent, building next-generation leaders
1867: The company, originally named the Union Elevator and General Machine Works by Elisha Otis, subsequently undergoes several name changes. In this year, Charles and Norton Otis change the company's name to Otis Brothers & Company.
1870s
A gilded age
Otis begins offering an ornate passenger elevator with additional safety features. Cabinetmakers build the cabs, which the Otis catalog compares to "sumptuous" apartments, "richly carpeted, with a large mirror and luxurious sofas around three sides."
1870s
A gilded age
1878: Otis introduces a roped hydraulic elevator that increases speeds to 244 meters (800 ft) per minute.
1880s
Power and steel
Two technological breakthroughs in the United States accelerate the emergence of the modern skyline. The steel I-beam, more durable than iron as a construction frame, enables architects to build taller structures. Simple rope-and-pulley hydraulic systems also help overcome early building height restrictions.
1880s

1880: The company receives contracts to install elevators in the U.S. Capitol and the White House.
1882: Charles and Norton Otis sell their stock and patents for $350,000 (about $10.4 million in 2023). The brothers are retained as consultants.
1884: Otis purchases the American Elevator Company and establishes sales offices throughout Europe.
1880s
Power and steel
1887: Otis wins the contract to supply elevators for the North and South pillars of the Eiffel Tower, which becomes the centerpiece of the 1889 Exposition Universelle in Paris. The curvature of the Tower’s pillars poses a unique technical challenge which Otis was able to meet. A century later, Otis is hired to modernize the two Duolifts during a major renovation. These elevators allow visitors to reach the top of the Tower from the 2nd floor.
1880s

1890s
Innovations push company forward
1898: Otis and 13 other companies merge to form a new entity with a new name, incorporated in New Jersey as The Otis Elevator Company. Norton Otis is board chairman and William Delavan Baldwin is president. The public company has a market capitalization of $11 million – the equivalent of ~ $404 million in 2023.
1900s
Otis expands further
In this decade and throughout his 32-year tenure as president and then chairman, Baldwin transforms Otis into a thriving entity by focusing on expansion, quality and innovation. Around the world, Otis elevators are installed in buildings of all heights and styles – utilitarian and opulent alike.
1900: An Otis moving staircase won the Grand Prix at the Exposition Universelle in Paris. Equipment inventor Charles Seeberger, teams with Otis and also coins the word “escalator,” using the Latin language. The word translates to “means of traversing from.” Seeberger trademarks it in 1899 but a U.S. federal court nullifies the trademark 50 years later, saying it has become so synonymous with the Seeberger/Otis moving staircase it is now generic.

1907: Twenty-one years after the Statue of Liberty was dedicated in New York Harbor, Otis installs the monument’s first elevator to carry visitors from the base to the top of the stone pedestal. The statue itself does not have elevators, so visitors may choose to walk the remaining 377 steps to the crown.
1910s
Underground, over water and around the world
1908 to 1912: In New York City, the 47-story Singer Building, the 50-story Metropolitan Life Tower and the 58-story Woolworth Building are all built. Each becomes the world’s tallest building at time of completion, surpassing the previous. All are equipped with gearless traction-machine elevators from Otis.
1910: Otis installs its first elevator in Korea at the Chosun Bank in Seoul. It is used to move currency from floor to floor.
1910s
Underground, over water and around the world
1911: The first two escalators to be used by London Transport are installed at Earl's Court Station. They are Otis A flat-step units, the forerunners of the heavy-duty escalator. The flat-step units are so successful that between 1911 and 1915, 22 machines are installed in the London Underground. The unit becomes the prime mode of passenger movement from station to street and continues to expand in popularity and acceptance.

Dubbed “robot elevators” for their automatic controls, the building’s passenger elevators handle tens of thousands of trips a day. The following decade, two elevators are added to expand capacity. When completed, the Empire State Building is the first to exceed 100 floors and becomes the world’s tallest building at 102 stories – until another Otis project, the north tower of the original World Trade Center, surpasses it in 1970.
1930s
Sustaining Otis through tough times
Service and modernization work exceeds new equipment sales beginning in 1932. This sustains the Otis business as the construction industry collapses during the Great Depression and beyond.
1930s
Sustaining Otis through tough times
1932: The Cities Service Building in New York City opens with the latest Otis innovation, a double-deck elevator. Each consists of two cabs joined vertically in the same hoistway. This enables eight cabs to do the work of 16, freeing up rentable building space while accommodating heavy passenger traffic during peak hours.
1940s
Wartime military support and post-war innovation
During World War II, Otis shifts to wartime production. It uses its expertise in science, engineering and factory management to manufacture ordnance, aircraft and ships in addition to elevators. The U.S. Navy employs hydraulic elevators from Otis to move aircraft onto aircraft carrier warships.
1940s
Wartime military support and post-war innovation
1945: The company emerges from the World War II stronger than ever, making elevators at a rate “substantially in excess of our prewar normal,” in the words of Leroy Peterson, chairman and president beginning in 1945.

Wartime military support and post-war innovation
1948: Otis Elevoice™ is included as an option for Otis Autotronic™ elevators while they still had attendants – two years ahead of attendant-free Autotronic systems – to help passengers adjust. A pre-recorded voice welcomes passengers and if the door is held open too long, it instructs: "Please let the doors close. You are delaying service.
1940s
Wartime military support and post-war innovation
1948: The 37-story Palmolive Building, a beautiful example of art deco architecture on Chicago’s Magnificent Mile, becomes the first building where Otis pipes music into its elevators. Psychologists theorize that soft music might distract passengers from “building sway.” Otis works with Muzak, a company founded in 1934 by Major General George Owen Squier, a pioneer in the transmission of multiple signals over electrical lines.
1950s
Deep in the heart of Texas – and around the world
