You’re probably reading this on a screen that connects to a local network, maybe while you’re waiting for a doctor’s appointment or sitting in a high-tech office. It feels like magic. But magic has blueprints. Honestly, if we look at the history of how we live now—everything from how we store blood to how we take a video call—the fingerprints of female African American inventors are all over it.
The weird thing? We don't talk about them nearly enough.
It’s not just about "representation" or being nice. It’s about the fact that these women literally built the structural bones of modern life while facing barriers that would make most people quit on day one. We’re talking about patents filed during Jim Crow. We’re talking about women who had to hire white men just to walk into a patent office for them. It’s intense.
The Laser Phaco Probe and the Fight Against Blindness
Let's start with Patricia Bath. She wasn't just "good" at her job; she was a force of nature. In 1986, she invented the Laserphaco Probe. If you know anyone who has had cataract surgery, they basically owe their vision to her. Before Bath, removing cataracts was a much more manual, risky, and frankly, invasive ordeal.
She saw a problem. She saw that Black people were twice as likely to suffer from blindness and significantly less likely to receive treatment. So, she didn't just invent a tool; she pioneered a whole discipline called community ophthalmology. It was a radical idea at the time. The concept was simple: eyesight is a basic human right.
The Laserphaco Probe uses a laser to vaporize the cataract through a tiny incision. It’s precise. It’s fast. And it changed everything. She was the first African American woman doctor to receive a medical patent. Think about that for a second. The first. In the late 80s. That’s not ancient history; that’s basically yesterday.
Why Alice Parker’s Gas Furnace Still Matters
Most people think of "invention" as some guy in a lab with a bubbling beaker. But sometimes, invention is born because you’re just cold. In 1919, Alice Parker filed a patent for a heating furnace.
Before her, if you wanted to stay warm, you were probably hauling wood or coal into a fireplace. It was dirty, dangerous, and inefficient. Parker’s design used natural gas. It was the first time someone thought, "Hey, maybe we could pipe heat into different parts of the building using a centralized system."

Did her exact design get built immediately? No. But her patent provided the blueprint for the central heating systems we use in almost every home today. She was a Black woman in New Jersey in 1919. Women didn't even have the right to vote yet when she submitted that filing. The courage that took is almost impossible to wrap your head around.
The Security System You Use Every Day
Ever look at a Ring doorbell or a Nest cam? You can thank Marie Van Brittan Brown for that. In 1966, she was a nurse living in Queens, New York. Her neighborhood wasn't exactly the safest, and her husband worked irregular hours. She felt vulnerable.
She didn't just buy a better lock. She created a system of four peepholes, a sliding camera, and a television monitor. She even added a two-way microphone so she could talk to whoever was at the door without opening it. There was even a panic button to alert the police.
- She wasn't a professional engineer.
- She was a nurse who wanted to feel safe in her own home.
- Her 1969 patent (U.S. Patent 3,482,037) is the foundation of the multi-billion dollar home security industry.
It's wild how often these stories get buried under the names of the big corporations that eventually commercialized the tech.
Dr. Shirley Jackson: The Mother of the Modern Connection
If you’ve ever used Caller ID, call waiting, or a portable fax machine, you’re using technology that stems from the research of Dr. Shirley Jackson. She was the first African American woman to earn a Ph.D. from MIT. That’s a heavy title, but her work at AT&T Bell Laboratories was even heavier.
She did the fundamental theoretical physics that enabled others to develop things like solar cells and fiber optic cables. Without her research into subatomic particles, your smartphone would basically be a paperweight. We often celebrate the person who "assembles" the gadget, but we forget the person who figured out the physics that makes the gadget possible in the first place.
Challenging the "Hidden Figure" Narrative
We’ve all heard the term "Hidden Figures" because of the movie. And while that movie was great, it kinda implies that these women were hidden by accident. Like someone just forgot to write their names down.

Actually, the exclusion was often systemic.
Take Gladys West. She spent decades at the Naval Surface Warfare Center. She was doing the complex mathematical modeling of the Earth's shape—the "geoid"—that eventually became the basis for GPS. For years, people just used the tech without knowing a Black woman had calculated the math that kept the satellites in sync. She didn't get public recognition for it until she was nearly 90 years old.
Imagine doing work that changes how the entire world navigates, and you don't get your flowers until you've lived a whole lifetime.
The Reality of the Patent Gap
Even today, there’s a massive "patent gap." Research from the Institute for Women's Policy Research shows that women—and especially women of color—are still underrepresented in patent filings. It's not because of a lack of ideas.
It's about access.
It's about funding.
It's about who gets the benefit of the doubt in a boardroom.
Historically, female African American inventors had to be twice as good to get half the credit. Sarah Boone, who patented an improved ironing board in 1892, had to design something so specifically better (it was curved to fit sleeves) that the patent office couldn't ignore it.
Digital Innovation and the New Guard
It’s not just about the 19th and 20th centuries. There are women right now, in 2026, who are pushing the boundaries of AI, biotech, and renewable energy.

Take Dr. Hadiyah-Nicole Green. She’s one of the few Black women in the world with a Ph.D. in physics and she’s developed a way to use laser-activated nanoparticles to treat cancer without the side effects of chemo. It’s groundbreaking. It’s also a reminder that the lineage of Patricia Bath is very much alive.
Then there’s Ruha Benjamin and Timnit Gebru. While they are often categorized as researchers or activists, they are inventing the frameworks for "Ethical AI." They are building the "brakes" for a technology that is currently screaming ahead without a steering wheel. That kind of intellectual invention is just as vital as a physical machine.
How to Actually Support This Legacy
If you're looking for ways to engage with this history or support the future of these creators, there are specific things you can do.
- Look at the USPTO records. The United States Patent and Trademark Office has been digitizing historical records. Searching for "Black women inventors" reveals thousands of stories that haven't made it into textbooks yet.
- Support STEM programs specifically for girls of color. Organizations like Black Girls Code aren't just teaching kids to type; they’re building the next generation of patent holders.
- Read the actual patents. If you really want to understand the genius of someone like Lyda Newman (who invented a better hairbrush in 1898) or Miriam Benjamin (who invented the "Gong and Signal Chair" for hotels), look at their technical drawings. The level of detail is staggering.
- Acknowledge the intersectionality. These women weren't just "inventors" and they weren't just "women." They were navigating a world that often didn't want them to succeed in either category. Their success is a testament to a specific kind of resilience.
The history of technology is often written as a series of "great men" doing "great things." But when you scratch the surface, you find Alice Parker’s gas furnace, Marie Van Brittan Brown’s camera, and Patricia Bath’s laser.
The world we live in was built by people who weren't always invited to the table. They just built their own tables, and then they built the house around them.
Next Steps for Further Exploration:
- Check the National Inventors Hall of Fame: Visit their digital gallery to see the latest Black women inductees, as they have significantly increased their documentation of minority inventors over the last five years.
- Verify Local History: Many states have specific archives dedicated to local inventors; for instance, New Jersey has extensive records on Alice Parker that offer more context than national summaries.
- Support Contemporary Founders: Use platforms like Fearless Fund or similar venture capital groups that focus on supporting Black women in tech and physical product development.
- Audit Your Curriculum: If you are an educator or parent, ensure that STEM discussions include these specific names rather than relying on the same three or four historical figures usually mentioned in February.
- Utilize Google Patents: Search for names like "Madam C.J. Walker" or "Sarah Goode" to see the original technical diagrams. Seeing the 19th-century drafts helps bridge the gap between "historical figure" and "technical expert."
The work of these women isn't just a footnote. It is the text itself. Understanding their contributions changes how you look at every piece of technology you touch. It moves from being a mystery of "science" to a very human story of problem-solving against the odds.
