The Origin of the Fan: From Hand-Held Breeze to Mechanical Thrust

Eight fans were unearthed alongside Tutankhamun in his tomb. One was an ivory hand fan, and when excavated, its ostrich feathers remained perfectly intact after 3,300 years. Remarkable as that preservation is, what deserves even greater attention is that this object was never merely a cooling device. In ancient Egypt, the “Fan-Bearer on the King’s Right Hand”—the official who held a fan at the pharaoh’s side—held one of the highest court offices, equivalent to a member of the royal guard.^[1] The act of moving air was itself a symbol of power.

Today, the word “fan” spans a single connected lineage: from the hand fan, to the electric fan, the windmill, the ship’s screw, the aircraft propeller, the helicopter rotor, and on to the turbofan of a jet engine. How old is the idea of moving air or water by displacing it with a blade? How did that idea spread and transform? And crucially, is the genealogy of the “fan” derived from the wheel, or did it evolve independently?

The Oldest Fan: Hand and Feather

The first “fan” humanity ever made was not a tool but an action. The origin likely lies in the instinctive motion of pushing air in front of one’s face on a hot day, or picking up a nearby leaf or branch and waving it. The earliest archaeological evidence of this intuitive act crystallizing into a tool appears in Egypt before 3000 BCE.

From the very beginning, the Egyptian fan served two simultaneous roles: cooling and sacred symbolism. The long-handled fan made of ostrich feathers—known as a flabellum—appears in tomb paintings being waved before pharaohs or divine statues during ritual scenes. In Egyptian mythology, a single ostrich feather represented the goddess Ma’at, embodiment of truth, justice, and cosmic order.^[1] The fanning motion was also linked to the belief that it could breathe life back into the dead, which is why fans were placed in the tombs of the wealthy.

Yet it was not Egypt but East Asia that achieved the next formal leap in the fan’s history. Fans made of bamboo, wood, and silk dating to around the 2nd century BCE survive from China, evidence of a fan culture that flourished early and diversified into many forms.^[2] But the folding fan (折扇, sensu) familiar to us today was first invented in Japan.

Japan’s folding fan is thought to have emerged in the early Heian period (794–1185 CE), around the 9th century. Its earliest form was the hinoki-ōgi (檜扇)—thin planks of Japanese cypress bound together—which have been excavated from Nara period (710–794 CE) sites. According to legend, the design was inspired by the way a bat’s wings fold and unfold, and the underlying structural principle was that “unfolding a collapsible surface creates a larger area to displace air.”^[3] Originally used at court as a surface for writing notes, these objects gradually acquired paintings and patterns, evolving into ceremonial ornaments. In the 10th century, the Japanese monk Chōnen (奝然) presented a folding fan to the Chinese emperor, effectively re-exporting the invention to China.^[3] By the 16th century, Portuguese merchants had brought folding fans to Europe, where each country developed its own distinct fan-making tradition.

The Fan That Catches the Wind: The Birth of the Windmill

If the hand fan uses human muscle to push air, the windmill inverts that logic. Air—wind—pushes the blades first, and that force turns the machine. This reversal may seem simple, but it represents one of the earliest instances in human history of converting natural energy into mechanical power.

The earliest windmill in the historical record was used around the 7th century CE in the Sistan region, corresponding to what is today eastern Iran and western Afghanistan.^[4] This “panemone” style windmill had blades made of bundled reeds or cloth sails rotating horizontally around a vertical axis. Rather than standing vertically, the blade surfaces were laid out horizontally, so that when wind blew in from the side it pushed the blades and turned the axle. The 9th-century Persian geographer Estakhri recorded that windmills were already operating widely across the Khorasan region.^[4]

While Persian windmills were the first to harness wind energy, European windmills followed a different evolutionary path. Developing in 12th-century Europe either independently or under Middle Eastern influence, the European windmill used a horizontal axis rather than a vertical one. Its sails stand upright and rotate—the classic image of the Dutch windmill we picture today. The oldest European written record definitively mentioning a windmill comes from the village of Weedley in Yorkshire, England, in 1185.^[5]

Here an important conceptual distinction emerges. How does a windmill blade differ from a wheel? The wheel is a device that minimizes friction with the ground to move weight. The windmill blade, by contrast, maximizes friction with a fluid (air) to capture energy. The two concepts share only the use of rotational motion; their purposes and underlying principles are fundamentally different. The windmill is not an application of wheel technology—it is an independent application of the same geometric principle of rotation toward an entirely different end.

From Screw to Propeller: Archimedes and Da Vinci

If hand fans and windmills worked with flat blades to manage air, mechanical history held a far more sophisticated concept from antiquity: the helix.

Archimedes (c. 287–212 BCE) devised a machine that placed a helical screw inside a cylinder to lift water from a lower level to a higher one. Known as the Archimedes’ screw, this device was the first sophisticated mechanism to use rotational motion to move a fluid along an axial direction.^[6] Some scholars argue, however, that a similar device already existed under the Assyrian king Sennacherib (704–681 BCE), suggesting the true origin may be even older.^[6]

The idea resurfaced roughly 1,700 years later. Around 1489, Leonardo da Vinci (1452–1519), then working as a military engineer under Ludovico Sforza in Milan, left behind a sketch he called the “Aerial Screw.”^[7] His idea was to apply the principle of the Archimedes’ screw not to water but to air: by spinning the helix, air would be pushed downward, lifting the machine upward. This is structurally identical to the modern helicopter rotor.

Da Vinci’s design was unrealizable with the technology of his time. There was no power source, no suitable structural material, and no way to counteract the rotational reaction force (torque). Yet the sketch contained a crucial conceptual leap: a fan or propeller, spinning through air, can generate thrust—the motion of blades can propel a machine. That idea was the essential insight.

The Industrial Revolution and the Birth of the Mechanical Fan

When the Industrial Revolution began in the late 18th century, the concept of the fan entered entirely new territory. As mines and factories expanded, one of the most pressing problems was ventilation. Toxic gases and smoke accumulated deep in underground shafts, and without a solution, catastrophic accidents were inevitable.

In 1727, British engineer John Theophilus Desaguliers demonstrated mechanically driven air circulation in a coal mine using a mechanical fan.^[8] Over the following decades, ventilation fans powered by hand, water wheels, or steam became central to mine safety. By the mid-19th century, large steam-driven centrifugal fans were widespread in mines and factories—devices that were, at their core, large vanes spun rapidly to force air from one place to another.

The arrival of electricity brought another turning point in the fan’s history. In 1886, American electrical engineer Schuyler Skaats Wheeler (1860–1923) attached a two-bladed propeller directly to the shaft of an electric motor to create the first electric fan.^[9] Called a “buzz fan,” the device ran on direct current and was considered dangerous due to its exposed rotating blades—but the invention earned Wheeler the John Scott Medal from the Franklin Institute in 1904.^[9]

Five years later, in 1887, German-American inventor Philip Diehl (1847–1913) attached blades to a sewing machine’s electric motor and mounted the assembly to a ceiling, thereby inventing the ceiling fan.^[10] Diehl later added a split-ball joint in 1904 to create the first oscillating fan capable of directional adjustment. The “wind-making device” that had begun as a hand fan had at last evolved into an electric consumer product.

The Screw Propeller Race: The Paradox of Simultaneous Invention

In the 19th century, the arena where the fan concept was most fiercely contested was the sea. The question of how to propel a steamship pitted the paddle wheel against the screw propeller in a rivalry that played out over decades.

On May 31, 1836, Francis Pettit Smith (1808–1874), a British farmer turned inventor, filed a patent for a screw-shaped propeller. Just six weeks later, on July 13, Swedish-born engineer John Ericsson (1803–1889) filed an independently developed patent for his own screw propeller.^[11] It was one of history’s not-uncommon cases of simultaneous invention.

When Smith’s propeller was accidentally broken in half during testing, the ship’s speed unexpectedly increased. This discovery—that a half-turn blade was more efficient than a full helical turn—laid the foundation for modern marine propeller design.^[11] In 1848, the Royal Navy put screw-driven HMS Rattler against paddle-driven HMS Alecto in a tug-of-war trial. Rattler pulled Alecto astern at 2.8 knots, officially confirming the superiority of the screw propeller.^[11] By the early 20th century, paddle wheels had nearly disappeared and the screw propeller had become the standard of maritime propulsion.

The Wright Brothers’ Propeller: Understanding the Fan as a Wing

On December 17, 1903, at Kitty Hawk, North Carolina, Orville Wright piloted the Flyer for just 12 seconds and 36 meters. Yet within that first powered flight lay a decisive insight that earlier aviation pioneers had missed.

Most aircraft designers before the Wright brothers understood the propeller as a device that “screws through the air the way a screw bores into wood, driving the machine forward.” The Wrights thought differently. In a wind tunnel they built on the second floor of their bicycle shop in Dayton, Ohio, they tested over 200 wing cross-sections and came to understand the propeller blade as a rotating airfoil—a spinning wing.^[12] Just as an aircraft’s wing generates lift, a propeller blade generates aerodynamic “lift” in the forward direction—thrust—as it rotates.

Working from that understanding, the Wright brothers hand-carved two spruce wood propellers, each roughly 2.6 meters long. Designed with a twisted structure that varied the angle of attack (pitch) along the blade’s length, these propellers achieved an efficiency of approximately 66 to 70 percent.^[12] That was extraordinary for the technology of the time. It was the moment the concept of the fan leapt from a simple air-moving device to a precision aerodynamic instrument.

The Dream of Vertical Flight: The Helicopter Rotor

On September 14, 1939—450 years after da Vinci sketched his aerial screw—Russian-born American aviation designer Igor Sikorsky (1889–1972) completed the first tethered flight of the VS-300 helicopter in Connecticut.^[13] This aircraft established the configuration that most helicopters follow to this day: one main rotor and one tail rotor.

The helicopter rotor is the most dramatic evolution of the fan concept. Where the Wright brothers’ propeller generated horizontal thrust, the helicopter rotor generates vertical thrust—lift—raising the machine straight up off the ground. The rotor simultaneously serves as the primary control surface. Through “cyclic pitch control”—periodically altering the pitch of each blade—thrust can be directed in any azimuthal direction. A machine that performs this many functions simultaneously through a single set of blades ranks among the most sophisticated achievements in the history of human engineering.

Sikorsky’s VS-300 developed into the world’s first mass-produced helicopter, the R-4, in 1942, and the design principles it established remain in use across the vast majority of helicopters worldwide.^[13]

Fan or Wheel Derivative: The Problem of Convergent Invention

We return now to the opening question. Did the fan derive from the wheel, or did it evolve independently?

To answer this, we must first clarify what “derive” means. The wheel’s core principle is that a circular component rolls on an axle, reducing friction with the ground to move an object. The fan’s core principle is that blades rotate or oscillate to move a fluid—air or water. Both use rotational motion, but their purposes and the media they interact with are fundamentally different.

Tracing the historical lineage reveals three distinct lines of invention.

First, the hand fan emerged entirely independently of the wheel. It developed directly from the act of waving one’s hand, and was refined separately in Egypt, China, and Japan.

Second, the windmill is conceptually distinct from the wheel. The Persian panemone windmill has a rotating axis, but this is not an application of wheel technology—it is an independent realization of fluid-dynamic principles (generating rotational force from air pressure). The European horizontal-axis windmill has an indirect connection to wheel technology insofar as it borrowed gear structures from the watermill, but the core concept of “blades that catch the wind” is an independent invention.

Third, mechanical fans and propellers are most closely connected to wheel technology. The electric fan, the ship’s screw, and the aircraft propeller all rely on sophisticated rotating axles and bearing systems—the very essence of wheel technology. The development of mechanical fans during the Industrial Revolution was directly intertwined with advances in steam-engine rotary gear technology.

In conclusion, the “fan” concept is a prime example of convergent invention. The hand fan emerged as a behavioral tool independent of the wheel, but as it was refined into mechanical devices, wheel technology played a decisive role. The Archimedes’ screw is a fascinating intersection of the two lineages, combining the fan’s purpose of moving fluid with an independent principle of helical rotation. The Wright brothers’ propeller was the complete synthesis of both lineages: airfoil theory (derived from the study of wings) and rotating machinery (derived from wheel technology).

Wings That Never Close

From the ivory fan of Tutankhamun, through the windmills of the Persian steppe, through the helix in da Vinci’s notebook, to the 12-second flight at Kitty Hawk—one thing has not changed across this entire journey. The idea of moving fluid with a blade has repeatedly transformed the way humanity solves its problems.

What is remarkable is that this concept remains open. The turbofan engines on today’s large aircraft draw in and compress air through a large front fan, and the design of those fan blades is the product of more than a century of aerodynamic research accumulated since the Wright brothers. At sea, systems like the Voith Propeller use vertical-axis multi-blade fans to enable 360-degree ship maneuverability. The small rotors of drones realize the principles of the helicopter rotor in a palm-sized package.

And at this very moment, somewhere, an engineer is calculating the optimal angle at which to twist a blade to move air more efficiently. Three thousand three hundred years separate that engineer from the fan-bearer of Tutankhamun, yet what both are dealing with is essentially the same: the human desire to move air, and the act of waving a blade to do it.
