10 Great Inventions by Women

Indeed, where would we be without women? Aside from the obvious fact that we wouldn’t exist, human civilization would be quite technologically impoverished. Below, we run through some of the greatest inventions by women.

It’s International Women’s Day (March 8th). In conjunction with the global celebration of the fairer sex, we look at some of women’s greatest contributions to humanity as a whole.

Stephanie Kwolek, a Polish-American chemist, is best known for the invention of poly-paraphenylene terephtalamide. Say, what?

Tabitha Babbitt – Circular saw (1813)

The circular saw is, of course, best known in horror or hardcore action movies, where it’s employed to dismember parts of the human body in a grizzly fashion.

Hedy Lamarr, Hollywood sex symbol and brilliant rocket scientist.
