Who invented the menstrual cup?

The first menstrual cup, made from rubber, was invented in 1937 by an American woman named Leona Chalmers.  Unfortunately for Chalmers, a wartime rationing of rubber during World War II impacted the production of her menstrual cup.

Her cup was met with resistance from the public. Perhaps ahead of its time, the idea was shelved due to the rise in the popularity of disposables and the invention of the applicator tampon.

Thankfully, the concept has gained more widespread popularity and recognition since the early 2000s when the Mooncup menstrual cup was invented.

Who invented the Mooncup?

Su Hardy is to thank for the invention of the Mooncup menstrual cup.

Su Hardy, inventor of the Mooncup menstrual cup

Su first came across a menstrual cup when she was travelling around Australia in 2000 and started to import and distribute it to friends and friends of friends when she came home to the UK. But discovering that some had a reaction to the latex in this rubber cup, she researched hypoallergenic alternatives and invented the world’s first reusable, medical grade silicone menstrual cup, trademarked as the Mooncup® in the spring of 2002.

Su built up the company from her spare room, working around the clock with a few friends, and it became an award-winning, international, employee-owned business based in Brighton.

In 2023, Mooncup officially join the &SISTERS family, a family-run sustainable period care brand specialising in compostable pads, tampons and liners.
