She took down her own shower curtain and cut it up.
She had two small children and she was sick of it the wet cots, the wet sheets, the wet clothes, the whole endless cycle of changing a baby only to have everything soaked again within the hour.
At the time, the only option on the market was rubber pants, which trapped moisture against the skin and gave babies terrible rashes.
So she sat down at her sewing machine with a piece of shower curtain and made something better.
Her name was Marion Donovan.
She had grown up around invention, which mattered. Her father and her uncle ran a machine tool factory in Indiana and had invented an industrial lathe for making car parts. Her mother died when she was just seven, so she spent much of her childhood at the factory, in among the machinery, watching things get built.
She later earned a degree in English, worked briefly at Vogue, married, and moved to Connecticut. When she had children, she looked at the everyday problems in front of her the way the people in that factory would have.
It took a long time and quite a few shower curtains.
The finished version was crafted from nylon parachute cloth waterproof, but breathable enough for the skin to dry rather than sit in moisture. It featured a pouch to hold an absorbent insert, keeping the wet layer away from the baby. And she got rid of safety pins the very things every mother of that era had accidentally stabbed herself or her child with replacing them with convenient snap fasteners.
She called it the "Boater," because it helped keep the baby afloat.
Then she took it to manufacturers. Every large company in the business. All the names you would think of.
They turned her down, and the reason they gave is worth repeating, because she recalled it in an interview with Barbara Walters years later: they told her they didn't want it. They said no woman had ever asked them for such a thing, that mothers were perfectly happy with what they had, and were buying all the baby pants the companies could make.
So she said fine, and went into manufacturing herself.
The Boater went on sale at Saks Fifth Avenue in New York in 1949, and shops couldn't keep it in stock. The president of Saks wrote to her personally to say it was rare for a new product in the infant wear department to meet with such immediate success.
She was granted her patent in 1951, and sold the company and rights that same year for a million dollars the equivalent of around ten million today.
By then, she was already working on her next idea, and this one was even harder: she wanted a diaper you could simply throw away.
That meant inventing a paper strong enough not to fall apart, absorbent enough to hold everything, and clever enough to pull moisture away from the skin rather than holding it there.
She worked it out.
Then she took it back to the same industry, and they turned her down again labeling it impractical and an unnecessary expense.
About a decade later, Procter & Gamble developed a product based on the same fundamental principle, which became Pampers turning disposable diapers into one of the largest consumer goods categories on earth. Donovan's work is widely credited as the direct forerunner of that revolution.
She didn't sit still afterward.
She enrolled at Yale to study architecture something she had always wanted to do and graduated in 1958 as one of only three women in her class. She even designed her own home in Greenwich.
She kept inventing for the rest of her life, ultimately earning twenty patents. Her creations included dental floss with a handle, a self-draining soap dish, a hanger for drying multiple garments at once, and a specialized tool for pulling a hairbrush through thick hair.
She was inducted into the National Inventors Hall of Fame in 2015, seventeen years after her death.
She started as a mother in Connecticut with a sewing machine and a ruined shower curtain, solving a problem an entire industry hadn't bothered to look at. And when that industry explained to her that women were happy as they were, she simply went out and sold it herself.
