Picture a 17th-century watchmaker furiously hand-cranking a wooden tricycle just to get to church. It sounds like a scene from a steampunk novel, but this was the humble, sweaty beginning of self-mobility. Long before we arrived at today’s sleek “peripatetic propulsion devices,” history was littered with steam-powered experiments and heavy, gas-guzzling failures that were more hazard than help.

But the electric wheelchair as we know it wasn’t born from mere curiosity; it was forged in the urgency of World War II. Enter George Klein, an unassuming Canadian engineer tasked with a critical mission: restoring independence to a generation of veterans who survived the battlefield but lost their mobility.

In this comprehensive post, we will navigate the fascinating timeline of the history of assistive technology—from the “almost” inventions of the early 1900s to the George Klein electric wheelchair breakthrough and the mind-controlled tech of the future. Buckle up. This isn’t just a story about motors and batteries; it is a chronicle of engineering evolution as the ultimate human triumph.

1. The Spark That Changed Mobility Forever

When we look at a modern power chair, we typically see a medical device. But for the person sitting in it, it is a vehicle of liberation. While George Klein rightly gets the lion’s share of the credit for the modern iteration, the story is actually a centuries-long relay race of innovators.

It is a history defined by a series of failures that eventually led to success. For instance, we often overlook the fact that a motorized chair appeared in London as early as 1916, but it was an utter commercial failure. Fast forward to the 1950s in Canada, and a similar concept became a triumph. Why? The difference wasn’t just the motor; it was the context. The electric wheelchair was born from a convergence of war, medical breakthroughs like penicillin, and a desperate societal need for independent living technology.

2. The “Almost” Inventions: Motorized Attempts Before Klein

Before the sleek designs of today, there were the clunky, loud, and often dangerous experiments of the early 20th century. These motorized wheelchair prototypes were fascinating engineering feats, even if they weren’t practical for daily life.

In 1916, London saw the debut of the first recorded “motorised power chair.” It was a heavy, tricycle-style contraption. While it technically worked, it failed to catch on for three reasons: it was prohibitively expensive, far too heavy for the architecture of the time, and there was simply no infrastructure to charge or maintain it.

Following this, the 1920s brought us the R.A. Harding Tricycle. This British attempt was an electrically propelled tricycle that offered a glimpse of what was possible, though it lacked the maneuverability required for indoor use. Across the pond, the Custer Car Company (circa 1915) was experimenting with hybrid models. They produced invalid cars that ran on gas and electricity. While these early power chair designs technically predated modern wheelchairs, they were closer to small automobiles than the agile mobility devices needed for home integration.

3. Ancient History: The Shoulders We Stand On

To understand the magnitude of the electric engine, we have to appreciate the struggle of manual propulsion. The evolution of personal mobility didn’t start with electricity; it started with the wheel itself.

As far back as 525 AD, Chinese stone carvings depicted early wheeled furniture used to transport the wealthy and infirm. However, these were not self-propelled mobility aids; they required a servant to push them.

The concept of self-propulsion didn’t arrive until 1655, thanks to Stephan Farfler, a paraplegic watchmaker from Nuremberg. Farfler refused to be dependent on others. He used his knowledge of cogs and gears to build a three-wheeled chair powered by hand cranks. He is, in many ways, the grandfather of independence.

4. The Catalyst: World War II and the Penicillin Miracle

Why did the electric wheelchair suddenly become a priority in the 1950s? The answer lies in a medical miracle that created an engineering crisis. Before World War II, a soldier who suffered a spinal cord injury on the battlefield had a grim prognosis; survival rates were incredibly low due to infection.

However, the mass production of penicillin changed everything. Suddenly, soldiers were surviving catastrophic injuries that were previously fatal. This created a new demographic: a large population of young, cognitively sharp WWII veteran rehabilitation patients returning home with quadriplegia and paraplegia. The manual wheelchairs of the time were useless to a quadriplegic veteran with limited arm strength.

5. Meet George Klein: The Unsung Hero of the 1950s

If there is a “father” of the modern power chair, it is George Klein. A Canadian engineer working for the National Research Council of Canada (NRCC), Klein was a tinkerer at heart. He grew up in his father’s jewelry store, which gave him a deep appreciation for precise mechanics—a skill set that proved vital for National Research Council Canada inventions.

The NRCC tasked Klein with helping the returning veterans. He approached the problem not just as a medical issue, but as a mechanical one. In 1953, he unveiled the “Klein Chair.” This was the first practical, mass-producible electric wheelchair.

Klein introduced key innovations that are still standard today:

• The Joystick: Klein realized that steering needed to be effortless. He developed a joystick drive that required minimal force.
• Separate Wheel Drives: To prevent motor burnout and allow for a zero-turn radius, he used independent drives for the wheels.

Perhaps the most noble part of the story is what happened to the patent. To ensure the technology reached as many veterans as possible, the patent rights were transferred to the US Veterans Affairs and made patent-free to encourage global production.

6. Everest & Jennings: The Duo Who Brought Power to the People

While Klein provided the spark, Everest & Jennings provided the fire. The story of Everest and Jennings mass production is central to wheelchair manufacturing history.

It began with a mining accident in 1918 that left Herbert Everest with a broken back. Dissatisfied with the wicker and wood chairs of the era, he teamed up with his engineer friend, Harry Jennings. In 1932, they invented the first folding tubular steel wheelchair. This X-brace design allowed the chair to be collapsed and put into a car, a feature that remains the industry standard for manual chairs.

In 1956, looking to expand their empire, E&J took Klein’s electric concept and applied their manufacturing prowess. They became the creator of the first mass-produced electric wheelchair. For decades, Everest & Jennings held a near-monopoly on the market, securing massive government contracts to supply veterans.

7. The Evolution of the Joystick: Mastering Control

The brilliance of the George Klein electric wheelchair lay in its control system. Before this, joystick control evolution was non-existent. Early attempts utilized tillers or steering wheels, which were impossible for a quadriplegic to use.

For high-level quadriplegics who could not use their hands at all, the “Sip-and-Puff” technology was developed, allowing users to drive by inhaling or exhaling into a tube. Today, we have proportional controllers, head arrays, and chin controls. This evolution in control interfaces expanded the user base from paraplegics to those with locked-in syndrome, ensuring electric mobility solutions were available to everyone.

8. The “Quickie” Revolution: Making It Cool and Lightweight

By the late 1970s, the “medical” look of wheelchairs—chrome and beige vinyl—was becoming oppressive. Users wanted performance and style, not just functionality.

In 1979, Marilyn Hamilton, a paraplegic hang-glider pilot, along with Jim Okamoto and Don Helman, introduced the “Quickie.” It was a revolution. They ditched the heavy steel of the “tank” era for lightweight aluminum and titanium. They introduced bright colors and sporty aesthetics. While the Quickie started as a manual revolution, its influence bled into the electric market, driving the demand for lighter frames and more personalized electric mobility solutions.

9. The Power Source: From Car Batteries to Lithium-Ion

You cannot discuss the history of the electric wheelchair without discussing the heavy lifting behind the scenes: the battery. Electric wheelchair battery evolution has been the single biggest factor in range and usability.

Klein’s early models utilized two heavy 6-volt car batteries. They were incredibly heavy, prone to leaking acid, and had a limited range. “Range anxiety” was a very real part of life for early adopters. The industry eventually standardized on 12-volt deep-cycle batteries, later moving to Gel and AGM (Absorbent Glass Mat) batteries which were safer for transport. Today, we are in the Lithium-Ion era, offering a fraction of the weight with longer life. For heavy-duty users requiring robust power for longer distances, checking out a wide seat electric wheelchair shows how battery tech supports larger frames today.

10. Little Drivers: The “Turbo” Chair for Toddlers

One of the most heartwarming chapters in mobility aids development occurred in the 1980s. At the time, medical professionals generally refused to prescribe power chairs to children under five, believing they lacked the coordination to drive safely.

David Everard disagreed. His daughter, Ruth, was 18 months old and had spinal muscular atrophy. Refusing to let her wait, Everard built the “Turbo” power chair specifically for her. Ruth proved the doctors wrong, navigating safely and happily. This invention forced a re-evaluation of pediatric mobility, proving that independent living technology should not have an age limit.

11. The Disability Rights Movement: Fighting for the Curb Cut

The best electric wheelchair in the world is useless if you can’t get into the building. The history of the chair is inextricably linked to the disability rights movement impact.

In the 1960s and 70s, the “Social Model” of disability began to take hold. Activists argued that people weren’t disabled by their bodies, but by the world around them. Ed Roberts and the “Rolling Quads” at Berkeley used their Everest & Jennings power chairs to attend university, breaking barriers simply by being present.

The pivotal moment came in 1990 with the “Capitol Crawl.” Dozens of activists abandoned their chairs and crawled up the steps of the US Capitol to demand the passage of the Americans with Disabilities Act (ADA). The ADA forced public transit and buildings to accommodate the weight and width of electric wheelchairs, validating the evolution of personal mobility as a civil right.

12. The Dark Side: Antitrust Suits and Market Monopolies

Business history is rarely without blemishes. As mentioned, Everest & Jennings dominated the market so thoroughly that by 1968, they controlled 90% of the industry. This lack of competition led to stagnation. Why innovate when you own the market?

In 1977, the US Justice Department filed an antitrust suit against E&J for price-fixing. The fallout from this suit eventually cracked the market open, allowing new players like Invacare and Permobil to enter the scene. This competition kickstarted a new era of smart wheelchair technology and better pricing for users.

13. 21st Century Tech: The Age of Intelligence

We have now entered the era of the “Smart Chair.” Modern companies are focusing on health as much as mobility. New electric mobility solutions include standing chairs and tilt-in-space functions that aid in pressure relief and circulation.

Safety has also taken a quantum leap. Systems like LUCI use radar and sonar—similar to the backup sensors in your car—to prevent the chair from tipping off curbs or colliding with obstacles. For those navigating complex environments, innovations like the stair-climbing wheelchair are breaking the final architectural barriers.

14. The Future is Now: Mind Control and AI

The future of power-assisted mobility sounds like science fiction. We are currently witnessing the birth of Brain-Computer Interface (BCI) technology. The “BrainGate” and similar experimental implants are allowing individuals with no physical movement to control their wheelchairs using only their thoughts.

Furthermore, autonomous driving is migrating from cars to chairs. Imagine a wheelchair that can navigate a busy airport terminal or hospital corridor on its own, avoiding pedestrians and finding the gate automatically. This represents the pinnacle of adaptive equipment innovation.

15. Conclusion: The Ultimate Freedom Machine

From Stephan Farfler’s hand-cranked tricycle to the George Klein electric wheelchair, and onward to AI-driven machines, the journey of the electric wheelchair is a testament to human resilience.

It is a story of WWII veteran rehabilitation driving engineering breakthroughs. It is a story of wheelchair patent history moving from open-source generosity to corporate monopolies and back to competitive innovation. Ultimately, George Klein’s invention remains one of the most vital of the 20th century. It didn’t just move a body from point A to point B; it moved lives forward. It proved that with the right independent living technology, physical limitations do not have to limit the human spirit.
