March is Women’s History Month, which makes it the perfect time to talk about the women inventors and women innovators who helped shape the world, even when history didn’t always give them the credit they deserved.
One of those women was Marjorie Joyner.
She may not be the first name that comes to mind when people talk about famous inventors, but she should be. Her story is a reminder that some of the best ideas don’t come from fancy labs or corporate boardrooms. They come from paying attention, staying curious, and noticing a problem that nobody has solved yet. That’s how inventors think. And Marjorie Joyner was clearly one of them.
Her invention helped transform the beauty industry, created new possibilities for Black women, and showed once again that women inventors have always been here, whether history books made room for them or not.
Marjorie Joyner Started Out During a Difficult Time
To understand how impressive Marjorie Joyner’s success was, you have to look at the time she was living in.
In 1928, it was difficult enough for women to get ahead in business. For African Americans, it was even harder. Jobs were limited, opportunities were scarce, and the obstacles were everywhere. But Marjorie Joyner was determined, talented, and not the kind of woman who was going to sit around waiting for someone to hand her an opportunity.
She went to work for Madame C. J. Walker, another remarkable woman who deserves her place in history. Walker built a hugely successful business creating hair care products specifically for Black women and became the first African American woman millionaire. That alone would have been groundbreaking. But she also built a network of trained saleswomen and stylists she called “hair culturists,” who went door to door selling products and styling hair in women’s homes.
That’s where Marjorie got her start.
At just twenty years old, she learned the business while working for the Walker Company and selling Walker products. But she wasn’t just learning how to style hair. She was learning how to see opportunity. She was learning how women inventors and businesswomen solve real problems for real people.
Why Women Inventors Often Notice What Others Miss
One of the things I love about stories like this is that they show how inventors think differently.
Inventors notice frustration. They notice wasted time. They notice what’s awkward, uncomfortable, inefficient, or unnecessarily hard. Then they start asking the question that leads to so many breakthroughs: what if there’s a better way?
Marjorie Joyner clearly had that mindset.
During the Depression, she stressed the importance of good grooming for both women and men who were looking for work. She understood something that is still true today: presentation matters. Looking polished and put together can affect confidence, first impressions, and opportunity.
She quickly moved up and became the national supervisor for the Walker Beauty Schools. Eventually, she owned her own salon. That alone would have made her successful. But what makes her unforgettable is that she didn’t stop at doing the job well. She started thinking about how to do it better.
That’s the difference between someone who works in an industry and someone who changes it.
How a Pot Roast Led to a Brilliant Invention
This is my favorite part of the story because it shows exactly how innovation so often happens.
Marjorie Joyner was making a pot roast one night when she noticed something unusual. The rods holding the roast together heated up from the inside. To most people, that would have been the end of the observation. Interesting, maybe. Then on with dinner.
But inventors don’t stop there.
Marjorie saw those heated rods and immediately connected them to a problem she had been thinking about in the beauty world. At the time, curling or waving hair was a slow, difficult process. Styling an entire head of hair took too long for both the stylist and the customer. So when she saw how those rods worked, the lightbulb went off.
What if heat could be applied in a way that would curl an entire head of hair at once?
That one question led to a breakthrough.
She built a simple prototype by attaching sixteen pot roast rods to a hair dryer hood. Then she experimented until she found a way to style hair so it would hold its shape for days. In 1928, she patented what became known as the permanent wave machine.
Think about that for a minute. She wasn’t sitting in some high-tech research facility with a team of engineers. She was solving a practical problem from everyday experience. That’s one reason I love talking about women inventors. Their stories remind us that innovation is often much more accessible than people think. Sometimes it starts in the kitchen. Sometimes it starts in a salon. Sometimes it starts with somebody noticing something everyone else ignored.
Marjorie Joyner Invented More Than One Solution
Another thing I admire about Marjorie Joyner is that she kept listening.
Once the permanent wave machine was in use, some customers complained that the rods burned their scalp. A lot of people would have shrugged and considered that just part of the process. Marjorie didn’t. She listened to the complaints and came up with another invention: a scalp protector that made the process less painful.
That matters.
The best innovators don’t just invent one thing and walk away. They refine. They improve. They pay attention to feedback. They understand that invention is not just about the big idea. It’s also about making the idea actually work better for the people using it.
That’s another reason women inventors have contributed so much throughout history. Many of them built solutions around real human needs. They understood the customer because they were close to the problem.
The Hard Truth About Not Profiting From the Idea
There’s also a frustrating part of Marjorie Joyner’s story, and it’s one that happened to far too many women inventors.
Even though she patented the permanent wave machine, she never made money from it. Because she was working for the Walker Company at the time, the company legally owned the patent rights. So the invention went on to make a lasting impact, but Marjorie herself never saw a dime from it.
That’s hard to hear, especially knowing how much her invention changed the beauty business.
But even that part of the story is important. It reminds us that women inventors have often had to fight not only to create something new, but also to be recognized and rewarded for it. The idea was brilliant. The impact was real. But the financial payoff didn’t go to the woman who came up with it.
Still, history should.
What Marjorie Joyner Believed About Women Inventors
Marjorie Joyner had a wonderfully direct way of talking about women in business. She said women “just have a whole lot of common sense. They can bridge the gap men don’t see. There is nothing a woman can’t do.”
Well put, Marjorie. Well put.
I love that quote because it doesn’t try too hard. It just tells the truth.
Women inventors have always brought something powerful to the table: practical intelligence, resourcefulness, empathy, observation, and a willingness to solve problems that others overlook. They bridge gaps. They see needs. They create answers.
And Marjorie Joyner did exactly that.
So during Women’s History Month, let’s make sure we celebrate the big names, but also the women whose stories may not be as widely known. Because history is full of women inventors like Marjorie Joyner who made life better, changed industries, and proved there is absolutely nothing a woman can’t do.
