Forgotten Genius Friday: The Enduring Legacy of Elijah McCoy — Is he the Man Behind “The Real McCoy?”
Discover how Elijah McCoy’s automatic lubrication system revolutionized steam engines and inspired the phrase “the real McCoy,” symbolizing quality and authenticity.
In the age of steam power, efficiency wasn’t just a luxury—it was a necessity. Trains, factories, and ships depended on complex machinery that required constant maintenance to function properly. Into this industrial challenge stepped Elijah McCoy, an innovator whose work would quietly transform mechanical engineering—and leave a lasting mark on American language.
From Skilled Engineer to Overlooked Worker
Born in 1844 in Colchester to formerly enslaved parents who had escaped via the Underground Railroad, McCoy showed early aptitude for mechanics. He later trained as an engineer in Scotland, gaining formal technical education that was rare for Black men of his time.
Despite his qualifications, racial discrimination limited his career opportunities when he moved to the United States. McCoy found work as a fireman and oiler on steam locomotives—positions far below his level of expertise.
But it was in this role that he identified a critical problem.
Solving a Costly Industrial Problem
Steam engines required frequent lubrication to prevent overheating and mechanical failure. At the time, trains had to stop regularly so workers could manually oil moving parts—wasting time, reducing efficiency, and increasing costs.
McCoy saw a better way.
He developed an automatic lubrication system that continuously applied oil to engine components while they were in motion. This innovation eliminated the need for constant stops and significantly improved performance across railroads and industrial machinery.
His invention quickly became indispensable.
“The Real McCoy”
As McCoy’s devices gained widespread use, imitations inevitably followed. But engineers and operators who valued reliability sought out his original designs—giving rise to the now-famous phrase “the real McCoy,” a term synonymous with authenticity and superior quality.
While the exact origin of the phrase is debated, McCoy’s reputation for precision engineering made the association both logical and enduring. While Elijah McCoy is often credited with inspiring the phrase “the real McCoy,” many historians and linguists dispute this connection. Evidence suggests the expression existed in various forms before McCoy’s inventions gained widespread recognition, and no definitive historical record links railroad engineers using the term specifically in reference to his lubrication systems. As a result, some scholars view the association as a compelling but likely apocryphal origin story—one that reflects cultural admiration more than documented linguistic history.Wikipedia
A Legacy of Innovation
Over the course of his career, Elijah McCoy secured dozens of patents, primarily focused on lubrication technology. His work extended beyond locomotives to ships, factories, and other machinery critical to the industrial economy.
His contributions helped:
- Increase efficiency in steam-powered transportation
- Reduce wear and tear on machinery
- Lower operational costs across industries
- Set new standards for mechanical reliability
Why Elijah McCoy Still Matters
McCoy’s story reflects both brilliance and resilience. Despite systemic barriers that limited recognition and opportunity, he produced innovations that became foundational to industrial progress.
His legacy is a reminder that transformative ideas often come from those closest to the problem—and that true quality stands the test of time.
The Spotlight on the Innovators
As part of STM Daily News’ Forgotten Genius Friday series, the story of Elijah McCoy highlights a powerful truth: innovation doesn’t always come from the spotlight—but its impact can echo for generations.
The next time you hear someone refer to “the real McCoy,” remember the engineer whose work kept the world moving.

🚨 Before Ring, There Was Marie Van Brittan Brown
Long before smart doorbells and mobile alerts became the norm, a nurse from Queens was already thinking ahead.
In 1966, Marie Van Brittan Brown, a Black woman living in New York City, felt unsafe in her neighborhood. Her husband, Albert, worked late hours, and she was often home alone. With crime on the rise and no real way to know who was at the door, she took matters into her own hands.
So she did what few people would think to do:
Home Security System
She invented the modern home security system.
🛠️ How It Worked
Marie and Albert Brown designed a closed-circuit television system with:
A camera mounted on the door Peepholes at different heights A live-feed monitor inside the home A microphone for two-way communication And a panic button to instantly alert the police.
In 1969, they were granted U.S. Patent No. 3,482,037, and that system laid the foundation for many of today’s smart home security tools.

🔄 Lasting Impact
Marie’s invention wasn’t just revolutionary—it was personal. Her system was designed for peace of mind, especially for women and families in vulnerable communities. Today, elements of her design show up in everything from Ring and Nest to intercom-equipped apartment doors.
She didn’t just protect her home—
she helped create the smart home.

Forgotten Genius Friday: The Legacy of Thomas Jennings — America’s First Black Patent Holder
Discover how Thomas Jennings, the first African American to receive a U.S. patent, revolutionized garment care with his dry-cleaning invention and supported abolitionist causes.
In the early 19th century, long before modern dry cleaners lined city streets, one man quietly transformed how Americans cared for their clothing. His name was Thomas Jennings—a tailor, entrepreneur, and trailblazer whose innovation would earn him a historic place in U.S. history.
Breaking Barriers in a Divided America
Born in 1791 in New York City, Jennings lived in an era when opportunities for African Americans were severely limited. Yet he built a successful tailoring business, gaining a reputation for craftsmanship and attention to detail.
At the time, cleaning delicate garments—especially wool—was a persistent challenge. Traditional washing methods often damaged fabrics, leaving customers frustrated and tailors searching for better solutions.
Jennings saw not just a problem, but an opportunity.
The Invention of “Dry Scouring”
In 1821, Jennings developed a cleaning method he called “dry scouring,” a precursor to modern dry cleaning. Unlike water-based washing, his technique used chemical solvents to remove dirt and stains without harming fabric fibers.
That same year, he achieved a groundbreaking milestone: Jennings became the first African American to receive a U.S. patent.
This was no small feat. Patent laws at the time largely excluded enslaved individuals, and systemic racism made legal recognition difficult even for free Black citizens. Jennings’ success marked a rare and powerful breakthrough.
“His achievement stands in stark contrast to what followed—when laws would deny many Black innovators the right to claim their own ideas.”
Innovation With Purpose
Jennings didn’t just profit from his invention—he used his success to support a broader cause. The income generated from his patent helped fund abolitionist efforts, contributing to the fight against slavery in the United States.
His work intersected with the growing abolitionist movement decades before the American Civil War, demonstrating how innovation and activism often went hand in hand.
Lasting Impact on Modern Life
Today, dry cleaning is a global industry, essential to fashion, hospitality, and everyday life. While technologies have evolved, the core concept Jennings pioneered remains intact.
His legacy can be seen in:
- The modern dry-cleaning industry
- Textile preservation techniques
- The broader recognition of Black inventors in American history
Why Thomas Jennings Still Matters
Jennings’ story is not just about an invention—it’s about access, perseverance, and impact. At a time when the odds were stacked against him, he secured intellectual property rights, built a business, and used his platform to support social change.
For today’s innovators, his journey underscores a powerful truth: meaningful breakthroughs often come from those willing to challenge both technical problems and societal barriers.
Final Word
As part of STM Daily News’ Forgotten Genius Friday series, the story of Thomas Jennings serves as a reminder that some of the most influential figures in American innovation history are still waiting to be fully recognized.
His invention didn’t just clean clothes—it helped clear a path for future generations of inventors.

💦 The Rocket Scientist Behind the Super Soaker
Lonnie Johnson, a NASA engineer, invented the Super Soaker, revolutionizing playtime after an accidental water release during an experiment. His success funded clean energy research and education initiatives.
It’s the ultimate summer toy. A backyard classic. A staple of water fights everywhere. But did you know the Super Soaker—one of the best-selling toys of all time—was invented by a NASA scientist?
This week on Forgotten Genius Fridays, part of our short video series The Knowledge, we’re telling the story of Lonnie Johnson, the brilliant engineer behind the water blaster that changed playtime forever.
👨🏾🔬 From Rocket Science to Soaking Wet
In 1982, Lonnie Johnson was working on a heat pump project in his bathroom. A former Air Force officer and NASA engineer, Johnson had already helped develop spacecraft systems, including work on the Galileo mission to Jupiter.
But one day, while experimenting with pressurized water and cooling systems, a valve released—and shot a stream of water across the room. That moment sparked a different kind of idea.
Johnson thought, “This would make a cool toy.”
🧪 The Road to the Super Soaker
Johnson built a prototype of a pressurized water gun unlike anything on the market. After years of rejections from toy companies, he finally licensed the design to Larami Corporation, a small toy maker that saw its potential.
In 1990, the Super Soaker hit store shelves—and exploded in popularity.
Within two years, it had sold over 20 million units, becoming a cultural phenomenon and sparking a line of high-powered water blasters. Eventually, Larami was acquired by Hasbro, which still sells Super Soakers today.
🌍 What Lonnie Johnson Did Next
Instead of just cashing in and disappearing, Johnson reinvested his success. He used Super Soaker royalties—estimated at over $1 billion in sales—to fund research in clean energy, including work on solid-state batteries and solar power.
He also founded the Johnson STEM Activity Center in Atlanta to help underserved students gain hands-on experience in science and technology.
