The Invention of the Elevator: How Otis Unlocked the Vertical City

In May 1854, a man stepped onto an open elevator platform before a crowd gathered at the Crystal Palace Exhibition in New York. He signaled his assistant, who swung an axe and severed the hoisting rope with a single blow. The crowd held its breath. The platform did not fall. It dropped only a few centimeters before locking firmly in place. Elisha Graves Otis turned to the audience and announced with perfect calm, “All safe, gentlemen.” ^[1]

That single demonstration changed the shape of cities forever. Yet the history of the elevator begins thousands of years before Otis was born. Humanity had long struggled with the problem of lifting heavy loads, and through that effort a lineage of technology was born — stretching from the underground chambers of Rome’s Colosseum to the summits of modern skyscrapers.

Ancient Lifting Devices: Human, Animal, and Water Power

The Roman architect Vitruvius recorded that around 236 BC, Archimedes built a primitive hoisting device in which a rope was wound around a drum and rotated using a capstan. ^[2] This combination of pulleys and rope was used at construction sites and harbors of the era to lift heavy loads.

Yet the most dramatic application of ancient lifting technology was found in the Roman Colosseum itself. ^[3] Beneath its floor lay a complex underground labyrinth known as the hypogeum. This subterranean network housed approximately 28 lifting mechanisms, each operated by eight slaves turning massive wooden axles on two decks. Each device could raise roughly 270 kilograms to the arena floor six or seven meters above. ^[3] Through these mechanisms, lions, tigers, and bears burst suddenly before the crowd, and gladiators made their dramatic entrances. This system — the original form of mechanical staging — was restored to near its original condition by Italy’s Ministry of Culture in 2019. ^[3]

Through the Middle Ages, simple rope windlasses were used in monasteries and castles to raise supplies. In 1743, at the Palace of Versailles, a device known as the “flying chair” was installed on the exterior of the building for Louis XV. ^[2] This was a private lifting apparatus for a single aristocrat, and it illustrates how from its earliest days the elevator was intertwined with power and privilege. In 1793, Russian inventor Ivan Kulibin installed a screw-driven lifting device in Saint Petersburg’s Winter Palace. ^[2]

Even When the Rope Snaps, It Does Not Fall: Otis’s Safety Brake

By the mid-nineteenth century, steam-powered hoists and lifting platforms were already widely used in mines, warehouses, and factories. There was one problem: if the rope broke, the passengers fell with it. This fear confined the elevator to freight-only service, and carrying people was considered unthinkable.

Elisha Otis solved this problem while working at a bed factory in Yonkers, New York. He developed a safety braking device based on the ratchet principle: a loaded spring that would engage with notches in the guide rail. ^[1] Under normal conditions, the tension of the rope kept the spring compressed and the brake disengaged. If the rope broke or its tension suddenly vanished, the spring would instantly extend and mesh with the protrusions on the guide rail, locking the cab in place. ^[1]

The principle itself was straightforward, but its consequences were anything but. Otis staged a dramatic public demonstration at the Crystal Palace Exhibition in New York in 1854 to prove the device’s safety. Notably, only two newspapers of the day — Scientific American and the New York Daily Tribune — covered the event. ^[1] The world was slow to grasp the significance of what Otis had invented.

But the market began to respond. On March 23, 1857, the first passenger safety elevator designed by Otis was installed at the E. V. Haughwout Building at 488 Broadway, New York. ^[4] This five-story cast-iron building sold fine china and glassware, and the elevator took about 40 seconds to travel one floor. The fare was ten cents per floor. When safety and convenience were combined, customers willingly paid to ride. By the time Otis died in 1861, his elevators were selling at a rate of roughly 300 units per year. ^[1]

The Age of the Hydraulic Elevator

Otis’s early elevators operated by winding a rope with a steam engine. This method was slow and limited buildings to moderate heights. Beginning in the 1870s, a new technology emerged: the hydraulic elevator. ^[5]

The hydraulic elevator worked by using water pressure to push a piston upward. From the 1870s through the 1890s, hydraulic elevators became the standard in New York’s major 10-to-12-story buildings. ^[5] Rope hydraulic elevators developed by Otis could reach speeds of up to 244 meters per minute — a remarkable figure for the era. ^[5]

Hydraulic elevators, however, had a structural limitation. The piston had to be sunk deep underground, and as buildings grew taller, the cost and technical difficulty increased exponentially. New York’s subsurface bedrock made this even more challenging. Breaking through the height barrier would require an entirely new technology.

The Electric Elevator and Gearless Traction: A True Revolution

In 1880, Germany’s Werner von Siemens unveiled the world’s first electric elevator in Mannheim. ^[6] The device mounted a motor on the underside of the cab and climbed a rack fixed to the wall — but it was not yet commercially competitive.

The true breakthrough came in 1902, when the Otis Elevator Company developed the gearless traction electric elevator. ^[5] In this system, an electric motor drives a sheave directly, and steel cables wrapped around the sheave connect the cab to a counterweight. The first installation in New York in 1904 made hydraulic elevators obsolete almost overnight. ^[5]

The gearless traction system was revolutionary in three respects. First, the theoretical height limit for buildings effectively ceased to exist. Second, operating speeds increased dramatically. Third, the counterweight system greatly improved energy efficiency. Otis introduced automatic door mechanisms in 1915, and in the 1950s unveiled a fully automated operating system that gradually consigned the elevator operator as an occupation to history. ^[7]

Without the Elevator, There Would Be No Skyscraper

The question of which came first — the elevator or the skyscraper — resembles the chicken-and-egg debate. But history gives a clear answer: the elevator came first.

Until steel-frame construction emerged in 1880s Chicago, building height was limited by the load that brick or stone walls could bear. Steel frames solved the load problem, but the fact that a taller building was technically possible did not mean people would come to live or work inside it. Climbing ten or more floors by staircase was commercially unworkable. The elevator filled that gap. ^[8]

The Auditorium Building erected in Chicago in 1889 symbolized the new era brought about by the combination of elevators and steel frames. Around that period, cities across the world began adopting new principles of construction. The logic — that elevators make tall buildings possible, and tall buildings make maximum use of urban land — became the foundation of twentieth-century city planning. ^[8]

If the elevator changed the height of buildings, the steel frame provided the skeleton to bear their weight. The two technologies were each incomplete on their own, but when combined, the template for the modern urban skyline was born.

The Inversion of Status: The Upper Floors Once Belonged to the Poor

Before the elevator, the social geography of tall buildings was the reverse of what it is today. The lower floors were the desirable ones. The wealthy chose ground-floor or second-floor residences to avoid the burden of climbing stairs; rent fell with each additional floor. Attics and topmost floors were the domain of poor tenants — poorly ventilated, difficult to heat or cool, and considered effectively uninhabitable. ^[9]

The elevator turned this hierarchy completely upside down. Once the upper floors were no longer inconvenient, the open views from height and the distance from street noise gained new value. In 1920s New York, developer Emery Roth designed terraced top-floor apartments, giving rise to the concept of the “penthouse.” ^[9] Before that point, the top of a building signified a cramped space under the roof; afterward, it meant the most expensive residential address in a city.

This reversal was not merely a shift in housing preference. A single invention rewrote the entire value system of the real estate market. Land values in elevated city-center locations surged, and developers gained the ability to subdivide a single plot of land vertically, creating multiple “air properties.” ^[8] The value of land extended upward into the sky.

Society inside the Elevator: The Sociology of an Enclosed Space

The elevator is not merely a means of vertical transport; it is also a peculiar social space. In a narrow metal box, strangers are compelled to coexist in momentary vulnerability. What the German sociologist Georg Simmel analyzed as the “blasé attitude” of the urban dweller appears in its most concentrated form inside an elevator. Passengers simultaneously notice and pretend not to notice each other, performing a subtle ritual of mutual non-acknowledgment. Most face the door or look down at their phones.

Historically, class tensions inside the elevator were sharper still. In late nineteenth-century Europe, there was social resistance to aristocrats and commoners sharing the same lift, and in some buildings separate elevators operated for different classes. ^[9] Even in modern buildings, the convention of distinguishing service elevators from main elevators preserves traces of this tradition. The elevator ostensibly offers a shared space for all, but in practice it created a new hierarchy mapped onto floor numbers.

The disappearance of the elevator operator as a profession is also worth noting. At one time, this job employed hundreds of thousands of people in cities. After fully automated systems were introduced, operators were let go, and in the 1950s and 1960s American elevator operators’ unions struck against automation. This makes the elevator a significant case study in the history of technological innovation and the displacement of labor. ^[7]

The Modern Elevator: A Subway in the Sky, Without Ropes

Today, more than five million elevators operate worldwide. ^[10] Approximately one billion people ride elevators every day — many times the number who travel by airplane. The elevator is the most heavily used and least celebrated form of transportation.

The most groundbreaking development in modern elevator technology is the MULTI system, unveiled in 2017 by the German company ThyssenKrupp. ^[11] This system drives elevator cabs using linear motors rather than ropes. Operating on a principle similar to maglev trains, MULTI allows multiple independent cabs to move within a single shaft and enables not only vertical but also horizontal travel. ^[11] The system was tested at a 246-meter-high test tower built in Rottweil, Germany.

If MULTI reaches commercial deployment, it could reduce the number of elevator shafts in a building and increase usable floor area by up to 25%. ^[11] Waiting times are projected to fall to within 15–30 seconds. If Otis’s rope-cutting moment 160 years ago opened the age of vertical mobility, MULTI heralds the next chapter — one that does away with the rope itself.

What makes the evolution of this technology impressive is not merely its speed or efficiency. Without elevators, the majority of existing skyscrapers would lose their purpose. The elevator is not an accessory to a building; it is the prerequisite for a building to exist at all.

The Skyscraper Race and the Elevator

The history of the world’s tallest buildings is also the history of elevator technology. The Burj Khalifa, standing at 828 meters, houses 57 elevators, some of which travel at speeds exceeding 600 meters per minute. ^[10] This was made possible by the shift from steel cables to high-strength synthetic fiber cables, along with advances in digital control systems.

As the race for height intensifies, the complexity of elevator systems grows in parallel. In a supertall building, it is physically impossible for a single elevator to run non-stop from ground level to the top floor — the cable’s own weight reaches its limit. For this reason, modern supertall buildings employ the concept of the “sky lobby.” A transfer hub is placed at an intermediate floor; high-speed elevators run from ground to sky lobby, and passengers transfer to local elevators that serve individual zones from there. ^[10]

This system is the answer to a fundamental question that has not changed in the 166 years since Otis’s demonstration: how can people be carried higher, more safely, and more quickly?

The Legacy of Otis

Elisha Otis died in 1861 at the age of 49. The elevator revolution he had set in motion was only in its opening stages. His sons Charles and Norton led Otis Brothers & Co. and grew the business, and today the Otis Elevator Company remains the world’s largest elevator manufacturer. ^[1]

The problem Otis solved in 1854 was simple: people must not be harmed when a rope breaks. But the possibilities that simple solution unlocked were vast. For thousands of years, the tallest structures humanity had built reached only a few dozen meters; after the elevator arrived, that limit exceeded 800 meters.

That limit is still being challenged. Projects such as the planned 1,600-meter Jeddah Tower and other mega-tower ventures are underway, and none of them can be realized without the next generation of elevator technology. From the craftsmen in the underground chambers of the Roman Colosseum who hauled lions onto the arena floor with pulleys and rope, to the MULTI cab moving horizontally between buildings on the principles of magnetic levitation — at the core of this long lineage there has always been the same question: how do we climb higher than we know how to build?
