In celebration of this year’s International Women's Day, Google has put together one of its iconic Google Doodles.

The Doodle features 13 “female pioneers”; many of whom are not known outside of their respective fields. If you’re wondering who these incredible women are, here they all are.

Ida Wells

Born into slavery, Wells was an anti-lynching crusader and suffragette. After three of her friends were attacked and lynched by a mob, Wells began a campaign speaking against the practice. She would later go on to become one of the founding members of the National Association for the Advancement of Colored People (NAACP).

Lotifa El Nadi

El Nadi earned her pilot’s license at the age of 26, after only 67 days of training. Because she could not afford the lessons, she worked as a receptionist at the airport.
