You’ve probably heard a few different names floating around when you look up the inventor of sanitary napkin. Maybe you’ve heard of Benjamin Franklin (no, really) or perhaps the South Indian social entrepreneur Arunachalam Muruganantham. The truth is way more chaotic than a single "aha!" moment in a lab. History doesn't usually hand out trophies to one person for something as fundamental as managing a period. It was a slow, sometimes gross, and often accidental crawl toward what we see on pharmacy shelves today.
For centuries, the "inventor" was basically anyone with a spare scrap of sheep's wool or a linen rag. Women just dealt with it. They used whatever was lying around. Think old rags, moss, or even sandbags in some cultures. It wasn't an industry; it was a private, annoying necessity.
The Battlefield Roots of the Modern Pad
Believe it or not, we owe a lot of our modern period products to war. In the late 1800s, specifically during the Franco-Prussian War, nurses realized that the cellulose bandages used for soldiers' wounds were incredibly good at absorbing blood. Much better than plain cotton.
These weren't sold in stores. They were improvised. Nurses started using these surgical dressings for their own menstrual cycles because, well, they worked. This is a recurring theme in the history of the inventor of sanitary napkin: the best ideas usually came from the people actually bleeding, even if their names didn't end up on the patents.
Then came Kimberly-Clark. Around 1914, their researchers developed a material called Cellucotton. It was cheap. It was made from wood pulp. When World War I broke out, this stuff was mass-produced for bandages. Again, the Red Cross nurses saw the potential. They were the ones who truly bridged the gap between medical waste and personal hygiene. When the war ended, Kimberly-Clark had a massive surplus of Cellucotton and nowhere to put it.
Kotex and the Branding Nightmare
In 1920, the first truly commercialized version of the modern sanitary napkin hit the market under the name Kotex (a mix of "cotton" and "texture"). But here's the kicker: nobody wanted to buy them. Not because they didn't work, but because people were too embarrassed to talk to a male shopkeeper about their period.
Imagine trying to buy a revolutionary new product when you're literally not allowed to say its name out loud in public.
To solve this, stores started putting out a "silent purchase" box. You'd drop your money in a jar, take a box of Kotex from the counter, and leave without saying a word. This wasn't just a product launch; it was a total shift in how society handled "the curse." It’s kinda wild to think that the inventor of sanitary napkin wasn't just a scientist, but a marketing team trying to figure out how to sell shame.

Why Benjamin Franklin Gets the Credit (Sometimes)
You might see Ben Franklin’s name pop up in trivia. People claim he’s the inventor of sanitary napkin.
Is it true?
Sorta. But not really.
Franklin is credited with designing a type of "biphasic" bandage to help wounded soldiers stop hemorrhaging. It was a practical, absorbent pad held in place by a belt. While he didn't design it for menstruation, his blueprint for a highly absorbent, belted pad is technically the ancestor of the "period belt" that women used well into the 1970s. He didn't invent the pad; he invented the delivery system for stopping blood flow in a hurry.
The Breakthrough of Johnson & Johnson
Before Kotex really took off, Johnson & Johnson tried their hand at this in 1896. They released "Lister’s Towels." They were named after Joseph Lister, the pioneer of antiseptic surgery.
The problem?
They were too ahead of their time. The public was horrified by the idea of a disposable product for something so "unspeakable." The product failed commercially because the world wasn't ready to acknowledge that periods existed on a retail level. It’s a classic example of having the right tech but the wrong era.

The 1970s: The Death of the Belt
If you ask your grandmother about the inventor of sanitary napkin, she might tell you about the "belt." Until the early 1970s, pads didn't have sticky backs. They were thick, bulky things that you had to safety-pin or clip to a literal elastic belt worn around your waist. It was uncomfortable. It shifted around. It was, honestly, a nightmare.
The real "inventor" of the modern user experience was the person who thought of the adhesive strip. Stayfree introduced the first "beltless" pad in 1969/1970. This changed everything. It seems like such a small thing—a strip of glue—but it was the difference between feeling like you were wearing a diaper and feeling like you were wearing underwear.
The Global Hero: Arunachalam Muruganantham
We can't talk about the inventor of sanitary napkin without mentioning the man known as "Pad Man."
In many parts of the world, specifically rural India, commercial pads were (and often still are) way too expensive. In the late 90s, Muruganantham realized his wife was using dirty rags because she couldn't afford brand-name napkins. He went on a mission to create a low-cost machine that could produce pads for a fraction of the cost.
He was mocked. His wife left him (temporarily) because he was so obsessed with testing his inventions—sometimes even wearing a "uterus" made of a football bladder filled with goat blood to test absorption.
He didn't just invent a pad; he invented a decentralized manufacturing model. His machines are now used in over 27 states in India and several other countries. He proved that the "inventor" isn't always a guy in a white coat at a multi-billion dollar corporation. Sometimes it’s just a guy who wants his wife to be healthy.
Material Science: What's Actually Inside?
Modern pads are marvels of engineering. Seriously. It’s not just cotton.

Most high-end pads today use Super Absorbent Polymers (SAP). These are tiny acrylic beads that can soak up about 30 times their weight in liquid. When they get wet, they turn into a gel. This is why a pad that is only a few millimeters thick can hold more than the massive "maternity pads" of the 1950s.
- Top sheet: Usually a perforated plastic film (polyethylene) that stays dry.
- Acquisition layer: This pulls the liquid away from the skin and down into the core.
- Absorbent core: A mix of wood pulp and SAP.
- Back sheet: A waterproof barrier to prevent leaks.
Is it eco-friendly? Mostly no. And that's the new frontier for the next inventor of sanitary napkin. We’re seeing a shift toward bamboo, organic cotton, and biodegradable bioplastics. The "invention" is currently being reinvented to keep it out of landfills for the next 500 years.
The Misconceptions We Need to Drop
People often think one person sat down and decided "I will help women." That's almost never how it happened. It was a series of pivots.
- Myth: Men invented it to control women's bodies.
Reality: While men often held the patents (because women weren't allowed to), it was almost always nurses and female factory workers who drove the functional design. - Myth: Disposable pads were always the goal.
Reality: For a long time, the goal was just to stop the "mess." Disposability was a luxury that only became possible with the industrialization of paper and wood pulp. - Myth: The design hasn't changed in 50 years.
Reality: Between the 1980s and now, the thickness of the average pad has decreased by over 50% while absorption has nearly doubled.
What’s Next for Period Tech?
The future of the inventor of sanitary napkin isn't actually a napkin at all. We're seeing a massive surge in period underwear and reusable silicone cups. The "disposable" era is being challenged by the "sustainability" era.
Companies are now experimenting with "smart pads" that can track iron levels or detect infections through menstrual blood. It’s turning a hygiene product into a diagnostic tool.
Actionable Insights for Today
If you're looking into the history of these products or trying to choose the best ones for your health, keep these points in mind:
- Check for TCF: Look for "Totally Chlorine Free" on the label. Some older bleaching processes left traces of dioxins, which aren't great for your body.
- Synthetic vs. Natural: If you have sensitive skin, the plastic top sheets on many big-brand pads can cause "pad rash." Switching to a brand with a 100% organic cotton top sheet usually fixes this immediately.
- The Cost Factor: If you're spending too much, consider a mix of reusables and disposables. The average person uses about 11,000 disposable products in their lifetime.
- Support Innovation: Look into social enterprises like Saathi (using banana fiber) or Be Girl (creating hybrid reusable/disposable gear for developing nations).
The story of the inventor of sanitary napkin is ongoing. It started with a rag, moved to a bandage, became a belt, turned into a sticker, and is now becoming a tech-integrated health product. It’s a testament to human grit and the refusal to let a natural biological process be a barrier to daily life.
