1) Kevlar
Kevlar was
invented by Stephany Kwolek in 1966. She invented a special material which is 5
times stronger than steel (the same weight). Being lightweight, Kevlar is widely
used for bullet prove vests. Nowadays
this material is an important element of parachutes, building materials, boats,
underwater cables etc.
2) Diapers
Diapers
were invented by Marion Donovan. In the market, there were already rubber baby
pants but they were pinching children’s skin. So she was thinking how to make
something which will make baby feel comfortable and women’s life easier. She
made experiments using her sewing machine and bathrooms curtains. As a result
she made something we are calling diapers now. And frankly we are very thankful
to her.
3) Liquid paper
Liquid paper was invented by Bette Nesmith Gramah, who was a secretary and had to type a lot. She found out better way to correct mistakes which her boss even can not realize. Step by step liquid paper became very popular among her colleges and she started her own company. She produced it in her kitchen but real success came to her when she got fired from her job and devoted all her time and energy for improving and production liquid paper . As a result she sold her company for 47.5 million USD.
4) Invisible glass
In 1938 Katherine
Blodgett after a bunch of experiments found out a way how to make invisible
glass which is completely transparent. Later on it used in microscopes, cameras, telescopes,
etc.
5) Windshield Wipers
This kind
of “men’s device”(In that time women were almost not driving) was invented by
woman Mary Anderson in the beginning of 20 century. By that time snow or rain were
making driving almost impossible and drivers had to stop every two minutes to clean
the windows. Mary Anderson found the solution, and patented it. But her idea became
recognized only after 10 years. And nowadays we even can’t imagine our cars
without windshield wipers.
6) Bra
Not a
surprise that brassiere was invented by woman. But anyway very useful and
widespread thing among women, designed by Ermina Kadol in 1889 in France.

| First Advertisement of Dish Washer |
Dishwasher was invented by Jozefien Kokrein. The idea came to her when somebody in
the kitchen broke her favorite porcelain set while cleaning it. She wanted to
have a machine which will clean the dishes and not break. But the way of achieving
her idea was quite long. When her husband died, he left her a lot of debts. As
soon as women didn’t want to sell her property, so she focused on her machine.
She got a patent, she constructed the machine but the problem was that nobody
wanted to buy it. People believed it is useless to pay for something that woman
can do for free. But she never gave up and step by step gained people’s trust.
Nowadays most of us find this device very helpful.
8) Snow-Fighting vehicle
Snow-fighting vehicle were invented in 1892. It comes out as result of woman’s willingness to see everything around clean (Perhaps for her it was not enough to clean just the house).
9) Circular saw

Circular saw
came to the world because of one curious woman; Tabitha Babbitt. While she was
observing her brothers working with woods, she noticed that even though the
load was distributed equally, the saw cat only one way and all other movements
were just a waist. She improved the process with a double spinning head. That
is how circular saw born.
10) Nystatin
Nystatin medicine was discovered in 1950. Nowadays it’s used for treatment Cutaneous, vaginal, mucosal and candida infections. It was invented by 2 women (Rachel Fuller Brown
and Elizabeth Lee Hazen) who were situated in different cities. They were sending to
each other different samples until they found the perfect one which won’t harm
people but will kill infections.
