Who run the world? Girls!

And not just any girls, but badass women who broke barriers and shattered stereotypes to make their mark in male-dominated industries.

From inventing street sweepers to designing rocket fuel, these ladies were not afraid to get their hands dirty and change the game.

So, grab a hard hat and a cup of coffee (or a martini, we don’t judge) and let’s take a look at some of history’s most inspiring women “sheroes” who made our world a better place, one invention at a time.

Emily Roebling – Brooklyn Bridge

We have all heard the joke “If you believe that, I have a bridge in Brooklyn to sell to you”.

But, what is no joke is that a woman played a HUGE part in the completion of the Brooklyn bridge.

It is 1872 and Washington Roebling falls terribly ill leaving him unable to manage one of the biggest projects of his lifetime.

What does a loving wife do?

Steps in of course!

Emily Warren Roebling was an American socialite and engineer who played a crucial role in the construction of the Brooklyn Bridge. Emily took over many her husband’s duties, including communicating with the workers and overseeing the construction. She was seen on site every day

She became an expert in bridge engineering and was able to complete the project alongside her husband. Emily’s contributions to the construction of the Brooklyn Bridge were groundbreaking and helped pave the way for women in engineering. She is remembered as a pioneer in her field and a symbol of perseverance and dedication

Tabitha Babbitt – Circular Saw

Those working in construction careers should be thanking Ms. Babbitt every day because her amazing invention makes their lives a whole lot easier.

Born in Hardwick, Massachusetts on December 9, 1779, Ms. Babbitt is the brains behind the circular saw. He invention was first used in a saw mill in 1813 and the rest as they say is history.

Her inspiration was born after she watched two men struggle to cut wood using a whipsaw. She felt that the effort they were using was being wasted and thought a round blade would be more effective.

We think she was right.
