The Teenager Who Outearned His Teachers
Before Dean Kamen became famous for inventing a scooter that would supposedly revolutionize transportation, he was a high school kid on Long Island making sixty thousand dollars a year. This was in the late 1960s. To put that in perspective, the average American household income at the time was around nine thousand dollars.
What was a teenager doing to earn that kind of money? Building light and sound systems for local bands and museums. While his classmates were flipping burgers or mowing lawns, Kamen was already getting paid for his ideas—a pattern that would define his entire career.
His father, Jack Kamen, was an illustrator for Mad Magazine and EC Comics, the company behind titles like Weird Science and Tales from the Crypt. Growing up in a household where creativity was literally how the bills got paid seems to have shaped Dean's understanding of what was possible. Ideas weren't abstract things. They were products.
The Dropout Who Saved Lives
Kamen enrolled at Worcester Polytechnic Institute, but he never graduated. He left in 1976 after five years—not because he was struggling, but because he was too busy succeeding.
While still a student, he had been conducting advanced research on something called an insulin pump. The device he developed, marketed through his company AutoSyringe, became the first drug infusion pump. If you've ever seen someone with a small device attached to their body that automatically delivers medication throughout the day, you're looking at technology that traces back to what Kamen built in his twenties.
The basic idea is elegant. Instead of requiring a diabetic patient to manually inject insulin multiple times a day, the pump delivers precise, continuous doses. It mimics what a healthy pancreas does naturally. This wasn't just an improvement over the alternative—it fundamentally changed what it meant to live with diabetes.
The same core technology—precisely controlling how fluids move through a system—became the foundation for portable dialysis machines. Dialysis is the process of filtering waste from the blood when a person's kidneys can no longer do the job. Traditional dialysis requires patients to visit a clinic several times a week and spend hours hooked up to large machines. Portable versions give people their lives back.
The Wheelchair That Climbs Stairs
In the 1990s, Kamen's company DEKA developed something remarkable: a wheelchair that could climb stairs.
Called the iBOT, it used gyroscopic stabilization—the same technology that keeps a spinning top upright—to balance on two wheels. When approaching stairs, the chair could rear up like a horse and use a set of rotating wheels to climb. The user could rise to eye level with standing people. They could traverse sand, gravel, and curbs.
Think about what this means. For someone who uses a wheelchair, the world is designed as a series of barriers. Stairs are everywhere. Curbs are everywhere. The iBOT didn't just make movement easier—it made entire environments accessible that had been closed off.
The technology that made this possible—sensors constantly monitoring balance, motors adjusting thousands of times per second, software predicting what the user intended to do—would soon find another application.
The Segway: When Hype Outruns Reality
In late 2001, something strange happened. Portions of a book manuscript leaked to the press, containing quotes from Steve Jobs and other technology luminaries about an invention so significant it would transform cities. The project was code-named Ginger. Speculation ran wild. Was it a teleportation device? A hovercraft? A new kind of engine?
It was a scooter.
The Segway Personal Transporter, unveiled in December 2001, was an electric, self-balancing vehicle. You stood on a platform between two parallel wheels and leaned in the direction you wanted to go. Sensors detected your shift in weight, and motors adjusted to keep you upright while propelling you forward.
The technology was genuinely impressive. The same gyroscopic systems that let the iBOT climb stairs now let riders stand effortlessly on two wheels. The learning curve was remarkably short—most people could ride within minutes.
But the hype had promised too much. Cities did not redesign themselves around Segways. Cars did not become obsolete. The product found niches—warehouse workers, tour groups, mall security guards—but never achieved the revolutionary adoption its boosters had predicted.
This is a recurring pattern with Kamen's inventions. The technology is often brilliant. The impact is often significant. But the gap between what he envisions and what the market embraces can be vast.
The Machine That Makes Water
About one in ten people on Earth lack access to clean drinking water. Waterborne diseases kill hundreds of thousands of children every year. The problem isn't that there isn't enough water—it's that the water people have access to is contaminated with bacteria, parasites, and chemicals.
Kamen's solution is called the Slingshot.
It's a vapor compression distiller, which is a fancy way of saying it boils water and captures the steam. Boiling kills pathogens. Capturing the steam leaves behind dissolved solids and contaminants. What comes out the other side is pure water.
This isn't a new concept—distillation has been around for centuries. What makes the Slingshot different is efficiency. Traditional distillation requires enormous amounts of energy because you're essentially boiling water away. The Slingshot recovers most of the heat from the steam and uses it to boil more water, dramatically reducing power requirements.
The machine is about the size of a dorm room refrigerator. It can produce about thirty liters of clean water per hour from almost any source—seawater, sewage, industrial runoff. It runs on a Stirling engine, a type of external combustion engine that can burn almost any fuel, including cow dung.
A documentary called SlingShot, released in 2014, followed Kamen's quest to deploy these machines in the developing world. The challenge isn't building the technology—it's building the distribution network, the maintenance infrastructure, the economic model that makes clean water sustainable in communities that have never had it.
The Arm That Feels
Losing a limb means losing more than mobility. It means losing the ability to feel textures, to gauge pressure, to perform the thousands of unconscious adjustments that make activities like tying shoelaces or cracking an egg possible.
Traditional prosthetic arms offer limited functionality. They might open and close a gripper. They might rotate a wrist. But the fine motor control that lets a human hand thread a needle? That's been out of reach.
DEKA's prosthetic arm, nicknamed the Luke Arm after Luke Skywalker's prosthetic hand in Star Wars, changes this. Approved by the Food and Drug Administration in 2014, it offers users control over individual fingers. Sensors in the arm detect muscle signals from the residual limb and translate them into movements.
The development was funded in part by DARPA, the Defense Advanced Research Projects Agency, reflecting the grim reality that advances in prosthetics often follow advances in warfare. Soldiers returning from Iraq and Afghanistan with traumatic limb injuries created both the need and the funding for better solutions.
The Competition That Created a Generation of Engineers
Ask Kamen what invention he's most proud of, and he won't mention the Segway or the insulin pump. He'll talk about FIRST.
FIRST stands for For Inspiration and Recognition of Science and Technology. It's a nonprofit organization that Kamen founded in 1989 with a simple premise: what if we made building robots as exciting as playing football?
Every year, FIRST announces a challenge. Teams of students have six weeks to design and build a robot that can complete that challenge. Then they compete—regionally, nationally, and finally at world championships.
The challenges vary dramatically. One year robots might need to shoot basketballs into hoops. Another year they might need to climb structures or move game pieces across a field. The constraints force creativity. The competition creates urgency. The teams—often hundreds of students working together—learn project management, mechanical engineering, programming, and how to work under pressure.
By 2020, the competition had grown to include over ninety thousand high school students on nearly four thousand teams. That's just the flagship event. FIRST also runs leagues for younger students, including partnerships with LEGO for elementary and middle schoolers.
The inventor Woodie Flowers, an MIT professor who helped create the competition format, introduced the concept of "gracious professionalism"—the idea that fierce competition and mutual respect aren't contradictory. Teams share knowledge. They loan parts to competitors. They celebrate each other's accomplishments.
Many FIRST alumni have gone on to careers in engineering and technology. The program has become a pipeline for companies looking to hire people who can build things.
The Factory for Human Tissue
In 2017, Kamen founded something that sounds like science fiction: the Advanced Regenerative Manufacturing Institute.
The basic challenge is this: we can now grow human tissue in laboratories. Skin for burn victims. Cartilage for damaged joints. Eventually, perhaps, whole organs. But laboratory techniques don't scale. Growing a patch of skin for one patient is very different from growing patches of skin for millions of patients.
ARMI's mission is to solve the manufacturing problem. How do you maintain sterility at industrial scale? How do you ensure consistency when you're working with living cells? How do you reduce costs enough that these technologies become accessible?
The institute operates through a public-private partnership, combining eighty million dollars in Department of Defense funding with over two hundred million dollars in private investment. The military's interest is practical: soldiers suffer burns and other injuries that could benefit from regenerated tissue.
The House That Invention Built
Kamen lives in a mansion in Bedford, New Hampshire, that defies easy description. He calls it Westwind. It's hexagonal. It's built in a shed style. It has at least four levels.
The hallways look like mine shafts. There's 1960s novelty furniture alongside antique wheelchairs. Secret passages connect rooms. An observation tower rises above the property. A fully equipped machine shop occupies part of the building.
And in the center atrium, rising through multiple stories, stands a massive cast iron steam engine that once belonged to Henry Ford. Kamen is converting it into a kinetic sculpture powered by a Stirling engine—because apparently owning a piece of automotive history isn't interesting enough unless you're also modifying it.
He commutes to work by helicopter. He owns three of them, along with a light jet. A hangar is built into the house.
The Question of Character
In December 2025, photographs emerged from the estate of Jeffrey Epstein showing Kamen with Epstein and Richard Branson on what appears to be a beach. Kamen stated the photos were probably taken on Branson's Necker Island and claimed no connection to Epstein.
However, Kamen's name had appeared in the flight logs of Epstein's private jet back in 2003. The full nature of any relationship remains unclear.
This is the complicating factor in any assessment of Kamen's legacy. He holds over a thousand patents. He has received the National Medal of Technology. He was inducted into the National Inventors Hall of Fame. He received a Global Humanitarian Award from the United Nations. These achievements are real.
And yet.
The same concentration of wealth and access that enabled his inventions also connected him to circles where darker things happened. This doesn't diminish the value of an insulin pump or the impact of FIRST on young engineers. But it does complicate the narrative of the lone inventor changing the world through sheer brilliance.
What Kamen Reveals About Invention
There's a pattern in Kamen's career worth examining. He solves hard technical problems—often brilliantly. The insulin pump works. The iBOT works. The Slingshot works. But the gap between a working technology and a transformed society is vast.
The Segway was supposed to change cities. It became a punchline. The iBOT was supposed to revolutionize mobility. It was discontinued due to cost, though it has since been revived. The Slingshot was supposed to solve the water crisis. The engineering challenge proved easier than the economic and distribution challenges.
This isn't a criticism of Kamen specifically. It's an observation about the nature of technological change. Inventing something is one kind of problem. Getting it into the hands of the people who need it, at a price they can afford, with the support infrastructure required to keep it working—that's an entirely different kind of problem.
Kamen is a remarkable engineer. Whether he's an effective agent of change is a more complicated question. His most successful intervention might be FIRST—not a product at all, but a system for developing people who can build products.
That competition has now touched millions of students. Some fraction of them have become engineers. Some fraction of those engineers are now solving problems that Kamen never imagined. The ripple effects continue.
Perhaps that's the real invention. Not any single device, but a mechanism for producing the next generation of inventors.
