Who Invented Cloth Nappies? The Marion Donovan Story
When we think of cloth nappies (or reusable nappies), we might picture soft cotton squares fastened with pins or snaps. But did you know that one woman’s frustration with soggy cloth nappies led to a breakthrough innovation that changed how we care for babies?
This is the story of Marion Donovan, a creative inventor whose everyday problem-solving would go on to influence the entire diaper industry.
Marion Donovan: Everyday Mom Turned Inventor
Marion O’Brien Donovan was born in 1917 in Indiana, USA. Raised in a family of inventors, she learned early that curiosity and hands-on tinkering could solve real problems.
As a mother in the late 1940s, Donovan was constantly washing her baby’s cloth nappies, clothes and bedding because traditional diapering methods leaked and caused irritation. Rubber pants — the common waterproof layering of the time — often led to rashes and didn’t keep babies dry.
The Breakthrough: A Waterproof Cloth Diaper Cover
Refusing to accept soggy messes as normal, Donovan took a materials-driven approach: she cut apart a shower curtain and used her sewing machine to fashion a waterproof cover to go over cloth nappies.
Her design — which she named the “Boater” — featured:
- Waterproof cloth that breathed, unlike rubber pants
- Snap fasteners instead of pins for safety and convenience
This was the first widely recognised modern diaper cover, addressing many of the major frustrations parents had long endured.
From Innovation to Market Success
Initially, major manufacturers didn’t think anyone wanted her product. But Donovan believed otherwise. She took her waterproof diaper covers to stores herself — and in 1949 debuted them at Saks Fifth Avenue in New York City, where they were an immediate success with parents.
In 1951, Donovan received a patent for her waterproof diaper design and sold the rights for about $1 million — an enormous sum at the time, reflecting the impact of her creation.
Did She Invent Disposable Diapers Too?
Marion Donovan didn’t stop at waterproof covers. She also developed one of the earliest designs for a paper-based disposable diaper, aiming to eliminate washing altogether. Unfortunately, companies at the time didn’t adopt the idea — but her concept laid groundwork that later innovators built on.
The first mass-market disposable diapers — such as Pampers — debuted in the 1960s following additional development by others in the industry. Donovan’s work was an important stepping stone to that innovation.
Beyond Diapers: A Life of Innovation
Marion Donovan was far more than a one-idea inventor. Over her lifetime she earned 20 patents for everything from household problem-solvers to clothing accessories — a testament to her natural ingenuity.
In 2015, she was inducted into the National Inventors Hall of Fame, recognising her lasting impact on everyday life.
Cloth Nappies Before Donovan
Cloth nappies themselves existed long before Donovan’s inventions. Caregivers used folded pieces of linen, cotton or flannel fastened with pins throughout history. The first cloth diapers were even mass-produced in the United States in the late 1800s.
What Donovan did was transform the cloth diapering experience by solving the age-old problem of leaking and discomfort.
Why This Matters Today
Marion Donovan’s story isn’t just about diapers — it’s about improving everyday life through thoughtful solutions to common problems. Her focus on practicality, safety and comfort resonates deeply with modern approaches to baby care, from reusable nappies to eco-conscious parenting.
From humble beginnings in her attic sewing room to retail success and patent recognition, Donovan’s journey is a powerful reminder that great innovation often starts with a real-world problem and a willingness to experiment.
