One of the most important African American leaders of the twentieth century and perhaps the most influential woman in the civil rights movement, Ella Baker (1903-1986) was an activist whose remarkable career spanned fifty years and touched thousands of lives.A gifted grassroots organizer, Baker shunned the spotlight in favor of vital behind-the-scenes work that helped power the black freedom struggle. She was a national officer and key figure in the National Association for the Advancement of Colored People, one of the founders of the Southern Christian Leadership Conference, and a prime mover in the creation of the Student Nonviolent Coordinating Committee. Baker made a place for herself in predominantly male political circles that included W. E. B. Du Bois, Thurgood Marshall, and Martin Luther King Jr., all the while maintaining relationships with a vibrant group of women, students, and activists both black and white.In this deeply researched biography, Barbara Ransby chronicles Baker's long and rich political career as an organizer, an intellectual, and a teacher. Beyond documenting an extraordinary life, the book paints a vivid picture of the African American fight for justice and its intersections with other progressive struggles worldwide across the twentieth century.
