Kimberlé Crenshaw is a pioneering scholar and writer on civil rights, critical race theory, Black feminist legal theory, and race, racism and the law. In addition to her position at Columbia Law School, she is a Distinguished Professor of Law at the University of California, Los Angeles.
Crenshaw’s work has been foundational in critical race theory and in “intersectionality,” a term she coined to describe the double bind of simultaneous racial and gender prejudice. Her studies, writing, and activism have identified key issues in the perpetuation of inequality, including the “school to prison pipeline” for African American children and the criminalization of behavior among Black teenage girls. Through the Columbia Law School African American Policy Forum (AAPF), which she co-founded, Crenshaw co-authored (with Andrea Ritchie) Say Her Name: Resisting Police Brutality Against Black Women, which documented and drew attention to the killing of Black women and girls by police. Crenshaw and AAPF subsequently launched the #SayHerName campaign to call attention to police violence against Black women and girls.
