While motorsport is often perceived as a man’s world, the history of racing is littered with trailblazing women who refused to accept the rules — both formal and informal — that prevented them from racing. And thanks to them, we’ve transformed the definition of what a racing driver can be.

From Camille du Gast in early-1900s city-to-city racing to Danica Patrick in NASCAR, each of these women competed under different rules and expectations, yet all faced similar pushback from the male-heavy institutions of motorsport. But more importantly, they all carved a space for themselves and for the women who followed.
