20 Inventions By Women That Made The World What It Is Today.

If you were asked for the names of great inventors, you'd probably come up with names such as Nikola Tesla, Thomas Edison, and Henry Ford. But what about Dr. Shirley Ann Jackson or Grace Hopper? You might not recognize their names right away, but you've definitely used their inventions. Keep reading to discover some of the world's greatest inventions that were brought to us by women.

#1. Some of the world's greatest inventions were created entirely by accident.

Such is the case of Scotchgard. While working in the 3M factory, Patsy Sherman accidentally dropped fluorochemical rubber on an assistant's shoe. They soon realized that it not only didn't damage the shoe, but it was water repellent, as well! Thanks to that mistake, we now have Scotchgard!

#2. Every time you look down at your caller ID, you can thank Dr. Shirley Ann Jackson.

Not only is Dr. Shirley Ann Jackson a brilliant theoretical physicist, but she's also the first African American woman to earn a Ph.D. from MIT. Dr Shirley Ann Jackson can also claim responsibility for fiber optic cables, solar cells, and the portable fax.

#3. Bette Nesbith Graham made it possible to cover up your mistakes.

As a secretary, Graham often made mistakes that needed to be corrected. Using white paint, she was able to hide any error she made. After spending a few years making the formula perfect, she patented the cover-up in 1958, calling it Liquid Paper. She later sold the patent to the Gillette Corporation in 1979, for $47.5 million.

#4. Thanks to Anna Connelly, people in big cities have a way to escape their apartment buildings during a fire.

In 1887, Connelly patented the very first fire escape. Without even realizing it, she created something that would save countless lives over the years.

#5. You know you've accomplished something when your invention is flying in outer space!

Puerto Rican scientist and inventor, Olga .D Gonzalez-Sanabria, spent the 80's developing a nickel-hydrogen battery that had a longer cycle life than anything else on the market at that time. Her batteries actually helped power the International Space Station.
