You woke up today because of a clock. You probably touched a thermostat, used a cell phone, or maybe even sat in traffic waiting for a three-light signal to turn green. We don't think about these things. They’re just... there. But the history of things black people invented isn't just a list of trivia for a school poster. It is the literal infrastructure of modern life. Honestly, if you stripped away the contributions of Black innovators from your house right now, you’d basically be sitting in a cold, dark box with no way to communicate and a very spoiled fridge.
History books have a weird way of smoothing things over. They focus on a few names, usually George Washington Carver and his peanuts, and then they stop. That’s a disservice. It’s boring. It ignores the gritty, legal battles and the sheer genius required to patent an idea when the law was literally designed to stop you from owning anything.
The High Stakes of the Patent Office
Before we get into the gadgets, let’s talk about the "why." For a long time, if you were enslaved, you couldn't legally own a patent. The logic? Since an enslaved person was considered "property," they couldn't enter into a contract with the government. Their ideas belonged to their masters. That didn't stop them, though. It just meant they had to be twice as smart and three times as fast.
Take Thomas Jennings. He’s a name you should know. In 1821, he became the first African American to receive a patent. He invented "dry scouring," which we now call dry cleaning. He was a free man in New York, and he used the money from his invention to buy his family out of slavery. That isn't just a "cool fact." It's a testament to how innovation was a tool for literal survival.

Revolutionizing the Way We Move
Ever been stuck at a red light? You can thank Garrett Morgan. But the story is more intense than just "he made a light." Before Morgan, traffic signals were basically just "Stop" and "Go." There was no middle ground. This led to horrific accidents where horses and early Ford Model Ts would smash into each other because they didn't have time to react.
Morgan saw a carriage and a car collide. He decided we needed a "yield" or a "caution" phase. He patented the three-position traffic signal in 1923. He eventually sold the rights to General Electric for $40,000. Back then, that was a fortune.
More than just traffic
Morgan wasn't a one-hit wonder. He also invented the "Safety Hood." We call it a gas mask now. To prove it worked, he literally wore it into a smoke-filled tunnel under Lake Erie to rescue workers trapped after an explosion. People were shocked. A Black man had saved the day using a device the "experts" were skeptical of. Sadly, when he tried to sell the mask, he often had to hire a white actor to pose as the inventor because fire departments in the South wouldn't buy from a Black man.
Then there’s Richard Spikes. Talk about a polymath. He’s responsible for:
- The automatic gear shift (1932)
- Improved brake systems
- The beer keg tap (Yes, really)
- Turn signals on cars
If you’ve ever used a blinker—and hopefully you do—you’re using technology refined by Spikes. He was losing his vision while working on his final designs, yet he still managed to finish the patent for the automatic gear shift.
The Digital Age and the PC in Your Pocket
When we talk about things black people invented, we have to look at the screen you’re reading this on. Silicon Valley likes to tell a very specific story about "two guys in a garage," but that story is missing some crucial DNA.
Mark Dean is a name that doesn't get enough credit. He’s an IBM engineer who holds three of IBM's original nine PC patents. He co-invented the ISA bus. That sounds technical, but basically, it’s the "plug and play" system that allowed your computer to talk to printers, monitors, and keyboards. He also led the team that created the first one-gigahertz chip. Without Dean, the personal computer would have remained a clunky, isolated machine rather than the versatile hub it is today.
The Mother of the Internet?
Not quite, but close. Dr. Shirley Jackson. She was the first Black woman to earn a Ph.D. from MIT. While working at AT&T Bell Laboratories, her theoretical physics research laid the groundwork for a massive leap in telecommunications. We’re talking:
- Portable fax machines
- Touch-tone telephones
- Solar cells
- Fiber optic cables
- Caller ID and Call Waiting
Think about that. Every time you see a "Scam Likely" call on your screen and decide not to pick up, you’re using tech that stems from Dr. Jackson’s work. She didn't just "invent a thing"; she mastered the science of how information moves through space.
Home Life and Personal Comfort
We take refrigeration for granted. You open the door, the light comes on, the milk is cold. Frederick McKinley Jones changed that. Before him, if you wanted to ship food across the country, you had to pack it in ice and pray. It was messy, expensive, and didn't work well.
Jones invented the "Thermo King." It was a portable air-cooling unit for trucks. This revolutionized the entire food industry. Suddenly, you could have fresh produce in the middle of a desert. It also saved countless lives during World War II because his units were used to transport blood and medicine to the front lines.
The Heat in Your House
Alice H. Parker. In 1919, she patented a central heating system using natural gas. Before this, people were mostly using wood or coal in fireplaces. It was dangerous and inefficient. Parker’s design was the precursor to the modern furnace. She envisioned a system where heat could be regulated and sent to different parts of a house through ducts. It was revolutionary for its time, especially for a woman of color in the early 20th century.
Realities and Misconceptions
There is a common misconception that these inventions were just "accidents." They weren't. They were the result of rigorous scientific Method.
Take Dr. Charles Drew. He is often credited with "inventing blood banks." That’s a bit of a simplification. What he actually did was much more impressive. He figured out how to separate plasma from whole blood. Plasma lasts much longer. He developed the standards for collecting, processing, and storing blood on a massive scale. He actually resigned from his post at the Red Cross because the military insisted on segregating blood by race—a practice Drew knew was scientifically baseless and morally wrong.
Breaking Down the Impact
It is easy to list names, but let's look at the sheer breadth of things black people invented across different sectors.
In the Kitchen:
Granville T. Woods was often called "The Black Edison." He had over 60 patents. While he did a lot for railroads (like the induction telegraph), he also invented a better steam boiler and an improved egg incubator. Then there's Alfred L. Cralle, who invented the ice cream scoop in 1897 because he noticed servers struggling to get ice cream out of containers with two spoons.
In the Bathroom:
The hairbrush was significantly improved by Lyda Newman in 1898. She designed it with synthetic bristles and a ventilation system that made it easier to clean. Before that, brushes were often made of animal hair and were a nightmare to maintain.
In Public Safety:
Marie Van Brittan Brown. She was a nurse living in Queens in the 1960s. She felt unsafe because the police took too long to arrive in her neighborhood. So, she invented the first home security system. It had a camera, two-way microphones, and a button to unlock the door or sound an alarm. If you have a Ring doorbell or a Nest cam today, Marie is the reason why.
Why This History Matters Right Now
Understanding the origin of these objects changes how you see the world. It’s not just about "diversity" in a textbook; it’s about acknowledging that human progress is a collective effort that has been frequently suppressed. Many of these inventors faced lawsuits, had their ideas stolen, or died in poverty while others got rich off their designs.
Lewis Latimer is a prime example. Everyone knows Edison "invented" the lightbulb. But Edison’s bulb used a paper filament that burnt out in a few hours. Latimer, working in Edison’s lab, invented the carbon filament. This made the lightbulb practical and long-lasting enough for everyday use. Latimer also drafted the drawings for Alexander Graham Bell’s telephone patent. He was the secret weapon behind two of the biggest inventions in human history.
Taking Action: How to Explore Further
If you want to move beyond just reading a list and actually engage with this history, here are a few ways to do it:
- Check the Patent Database: You can actually look up these original patents on the USPTO website. Searching for names like Granville T. Woods or Sarah Boone (who improved the ironing board) lets you see their actual technical drawings.
- Support Modern Innovators: The legacy of these inventors continues. Look into organizations like the National Society of Black Engineers (NSBE) or Black Girls Code. The hurdles today are different—usually involving venture capital gaps rather than legal ownership of their own bodies—but the genius is the same.
- Visit Museums: The National Museum of African American History and Culture in D.C. has an incredible section on innovation. Seeing the physical objects, like Jones's cooling units or Morgan's original masks, makes it real.
- Question the Narrative: Next time you hear a "Great Man" theory of history that only includes one demographic, ask who was in the lab with them. Ask who drafted the blueprints. Usually, the story is much wider than we're told.
Innovation isn't a solo sport. It's a relay race. The people mentioned here ran their laps under conditions most of us can't imagine, and they still handed off a world that is safer, faster, and much more connected.
