International Women’s Day is an opportunity to recognise the importance of women in innovation and reflect on the many devices and everyday items invented and patented by women. Here are just a few of the many talented women whose contributions have improved the way we live today.

Marion Donovan (1917 – 1998)

Marion Donovan was an American inventor and entrepreneur who was granted 20 patents from 1951 to 1996. Perhaps her best known invention was one that has helped millions of new parents – the precursor to the waterproof disposable diaper.

Donovan crafted a diaper cover that would prevent leaks and also be comfortable for her baby. Unlike other products on the market, her product was made of a cloth that allowed the skin to breathe and also included snap fasteners instead of safety pins. The “Boater”, as she called it, was rejected by many big name manufacturers she approached, so Donovan decided to make and market the product herself. After selling the Boaters in New York’s Saks Fifth Avenue in 1949 she was granted her patent in 1951 and then sold the rights to Keko Corporation that same year for $1 million.

She was inducted into the National Inventors Hall of Fame in 2015.

Beulah Louise Henry (1887 – 1973)

Beulah Henry was a prolific American inventor, nicknamed “Lady Edison” she patented her first invention at age 25.

Moving from North Carolina to New York, she worked as an inventor for the Nicholas Machine Works from 1939 to 1955. She also worked as a consultant for many companies that manufactured her inventions, including the Mergenthaler Linotype Company and the International Doll Company.

While living in New York, Henry established 2 companies: the Henry Umbrella and Parasol Company and later B.L. Henry Company.

Obviously there are so many more women we could have mentioned here. The next time someone mentions Thomas Edison, tell them about these exceptional women.
