There is a lot to celebrate from the various contributions made by women inventors and entrepreneurs, and National Women’s History Month is the best time to recognize all their efforts. Several items that we use in our everyday life were invented by women. Let’s take a look back at some of the key inventions by women inventors, that changed the world:
1. Computer algorithm
Inventor: Ada Lovelace
Ada Lovelace added her own notes when translating the lectures of her mathematics professor. Later, she was credited with penning the world’s first computer algorithm.
Inventor: Josephine Cochran
Cochran came up with the invention to use water pressure, instead of scrubbers that were used back then, to clean dishes. Although there were other prototypes, Cochran’s design was the most effective one from the rest.
3. Fire escape
Inventor: Anna Connelly
Connelly invented an external metal staircase which acted as the first fire escape and saved lives from deadly fires. Moreover, her invention resulted in the modification of the New York City building codes, and required residential buildings to have a secondary means of escape for emergencies.
4. Medical syringe
Inventor: Letitia Geer
Medical practitioners were using syringes that required the use of both hands to administer injections. Geer invented the one-handed syringe that is used by all medical practitioners today.
5. Windshield wiper
Inventor: Mary Anderson
Anderson was refused by manufacturers when she tried to sell her new windshield cleaning device. However, it was only after 10 years, and after her patent expired, that a similar device became a standard on cars.
6. Bullet-proof fiber
Inventor: Stephanie Kwolek
DuPont researcher Stephanie Kwolek, while searching for a lightweight and strong plastic for use in car tires discovered what is now known as Kevlar. This fiber has found numerous applications in canoes, bridge cables and frying pans. Most importantly, it is credited with saving countless lives in the form of bullet-proof vests.
7. The first Monopoly game
Inventor: Elizabeth Magie
“The Landlord’s Game” which was patented in 1904 was initially designed to showcase the evils of unchecked capitalism. Close to 30 years later a man patented a very similar game called Monopoly and sold it to Parker Brothers.
As we celebrate our successes as pioneering women in business, we must also acknowledge the many struggles women face every day, and jointly work towards overcoming our mutual challenges. So on this special day - International Women's Day, give your female relatives and friends a thoughtful gift!
