You’re probably reading this on a device connected to Wi-Fi. Or maybe you're using Bluetooth headphones. Honestly, most people just assume these things were dreamed up by some guy in a Silicon Valley garage. That's usually the narrative, right? But if you actually dig into the history of female inventors and inventions, you realize that the foundation of our entire modern, connected world was laid by women who were often ignored or flat-out sidelined.
It’s wild.
Take Hedy Lamarr. People knew her as a Hollywood star in the 1940s—literally "the most beautiful woman in the world." But she spent her nights tinkering with radio frequencies. She and composer George Antheil developed "frequency hopping," a way to stop torpedoes from being jammed by enemies. They actually got a patent for it in 1942. At the time, the Navy basically told her to go sell war bonds instead of messing around with engineering. Decades later, that exact technology became the backbone of Wi-Fi, GPS, and Bluetooth.
We’re talking about a movie star who basically invented the way your phone talks to your router.
Why we still get the history of female inventors and inventions wrong
History isn't always a lie, but it’s definitely a filter. For a long time, the patent office was a gatekeeper that many women couldn't even reach. Before the late 19th century, in many places, a married woman couldn't even legally own property, which included intellectual property. So, what happened? They filed under their husbands' names. Or their fathers'. Or they just didn't file at all and let the boss take the credit.
This isn't just about being "fair." It’s about factual accuracy.
When we talk about the first computer programmer, we have to talk about Ada Lovelace. This was the mid-1800s. She wasn't just doing math; she saw that Charles Babbage’s "Analytical Engine" could do more than just calculate numbers. She realized it could follow a series of instructions to create anything—music, art, complex data. She wrote the first algorithm. She saw the "computer" a century before it actually existed.
And yet, for years, she was relegated to a footnote as Babbage's "assistant" or "interpreter." That's a massive mischaracterization of her actual technical contribution.
The domestic tech revolution
We tend to think of "inventions" as big, clunky machines or digital code. But look at your kitchen. Look at your car.
Mary Anderson invented the windshield wiper in 1903. She was riding a trolley in New York City during a snowstorm and noticed the driver had to keep the window open to see. It was freezing. She sketched out a hand-operated lever from inside the vehicle. People laughed. They said it would distract drivers. Cadillac was the first to make it standard, but only after her patent expired. She never made a dime.

Then there’s Josephine Cochrane. She was a socialite who got annoyed that her servants kept chipping her fine china while washing it by hand. She didn't just complain; she went to her shed and built a machine that used water pressure to clean dishes. She won a prize at the 1893 World’s Columbian Exposition. Her company eventually became KitchenAid.
Think about that next time you load the dishwasher.
The life-saving impact of female ingenuity
If you move into the realm of medicine and safety, the list of female inventors and inventions gets even more intense. It’s not just about convenience; it’s about survival.
Stephanie Kwolek was a chemist at DuPont in the 1960s. She was looking for a new, lightweight fiber for tires because everyone thought there was going to be a gasoline shortage. She found a liquid crystalline solution that most researchers would have just thrown away because it looked "cloudy and thin." She insisted on testing it.
That "mistake" became Kevlar.
It’s five times stronger than steel. It’s in bulletproof vests, bridge cables, and spacecraft. Thousands of police officers and soldiers are alive today because Kwolek didn't follow the "standard" procedure for disposing of chemical waste.
Breaking the code: Grace Hopper and the COBOL legacy
If you’ve ever heard the term "debugging," you can thank Rear Admiral Grace Hopper. She literally found a moth in a relay of the Harvard Mark II computer in 1947 and taped it into the logbook.
But her real genius was COBOL.
Before Hopper, you had to speak "math" to talk to a computer. It was all binary, all symbols. She believed that we should be able to program computers using English-like commands. Her peers thought she was nuts. They told her computers didn't "understand" English. She did it anyway. Today, COBOL still runs a massive chunk of the world's banking and insurance infrastructure.

The social barrier to recognition
It’s easy to look back and say, "Wow, things were tough then." But even now, women represent a relatively small percentage of patent holders. The "Global Innovation Index" consistently shows a gap. Why?
Part of it is the "Matilda Effect." It’s a term coined by Margaret W. Rossiter to describe the bias where female scientists' work is attributed to their male colleagues. It happened to Rosalind Franklin with the structure of DNA. It happened to Lise Meitner with nuclear fission. Meitner’s colleague Otto Hahn won the Nobel Prize for it. Meitner, who actually explained the physics of what was happening, got nothing.
It’s kinda frustrating when you look at the data.
But there’s also the issue of venture capital and funding. Even in the 2020s, female-led startups get a tiny fraction of the funding that male-led teams do. Innovation requires resources. If you don't have the cash to prototype, your invention stays in your head.
Modern trailblazers you should know
It’s not all 19th-century history.
- Dr. Shirley Jackson: The first African American woman to earn a Ph.D. from MIT. Her research in theoretical physics led to the invention of the touch-tone phone, fiber optic cables, and the technology behind caller ID.
- Ann Tsukamoto: She co-patented a process to isolate human stem cells in 1991. This is foundational for cancer research and potentially curing dozens of diseases.
- Radia Perlman: Often called the "Mother of the Internet" (though she hates the title). She invented the Spanning Tree Protocol (STP), which is basically how network bridges communicate. Without it, the internet as we know it would constantly crash.
Misconceptions about female inventors and inventions
People love a "eureka" moment story. They want to believe Josephine Cochrane just woke up and had a perfect dishwasher in her head.
The reality is much grittier.
Most of these women were working against active hostility. They weren't just "inventing"; they were navigating legal systems that tried to block them and social circles that mocked them. When Mary Anderson tried to sell her windshield wiper patent, a Canadian firm told her, "we do not consider it to be of such commercial value as would warrant our undertaking its sale."
Short-sighted? Definitely.

Also, we often assume these inventions were "softer" or more focused on the home. That’s a total myth. Look at Patricia Bath. She invented the Laserphaco Probe for cataract surgery. She transformed how we restore sight to people. Or look at Sarah Goode, the first African American woman to receive a U.S. patent. She invented a folding cabinet bed—a precursor to the Murphy bed—to help people living in tiny apartments. These were practical, hard-engineering solutions to real-world problems.
Practical ways to support modern innovation
So, what do we do with this info? Knowing the history is great, but the goal is to make sure the next Hedy Lamarr doesn't get told to just "go sell war bonds."
First, check out organizations like Girls Who Code or Society of Women Engineers (SWE). They aren't just feel-good groups; they provide the technical training and networking that was denied to women for centuries.
Second, if you’re an investor or in a position to hire, look at the "hidden" talent. Data shows that diverse teams are more innovative because they approach problems from angles that a monolithic group just won't see.
Third, call out the "Matilda Effect" when you see it. If a woman in a meeting has a great idea and a guy repeats it five minutes later and gets the credit, speak up. "Yeah, like Sarah just said..." It sounds small, but that’s how you stop history from repeating itself.
Actionable insights for aspiring inventors
- Document everything. The patent process is brutal. Keep a dated, witnessed lab notebook. This saved many women in the past who had to prove they were "first to invent."
- Find a mentor who doesn't look like you. Sometimes the best advice comes from someone who has navigated the barriers you're currently hitting.
- Learn the business side. Invention is only half the battle. Understanding licensing, patents, and venture capital is how you keep control of your creation.
- Don't wait for permission. Almost every woman mentioned here was told "no" or "that's impossible." Do it anyway.
The history of female inventors and inventions is still being written. We're moving away from the era of the "hidden figure" and into an era where recognition is becoming the standard, not the exception. But it requires staying skeptical of the "lone male genius" trope and actually looking at the names on the patents.
Next time you use a GPS, think of Hedy. When you load the dishwasher, think of Josephine. When you write a line of code, think of Ada. These aren't just stories; they are the literal tools of our lives.
