Kimberlé Williams Crenshaw's work as a legal scholar has been massively influential. She coined the term “intersectionality,” which refers to the way multiple interlocking systems of power overlap to shape people's lived experiences.

Her work has also faced its share of pushback. She came up with the phrase "critical race theory," a subject that has been widely misunderstood as it has become a flashpoint in the culture wars.

But when Professor Crenshaw meets controversy, she isn’t afraid to talk back. Hence the title of her new book, Backtalker: An American Memoir.
