Ella Baker was an African-American civil rights and human rights activist. She was a largely behind-the-scenes organizer whose career spanned more than five decades. In New York City and the South, she worked alongside some of the most noted civil rights leaders of the 20th century, including W. E. B. Du Bois, Thurgood Marshall, A. Philip Randolph, and Martin Luther King Jr. She also mentored many emerging activists, such as Diane Nash, Stokely Carmichael, Rosa Parks, and Bob Moses, whom she first mentored as leaders in the Student Nonviolent Coordinating Committee (SNCC).

Baker criticized professionalized, charismatic leadership; she promoted grassroots organizing, radical democracy, and the ability of the oppressed to understand their worlds and advocate for themselves. She realized this vision most fully in the 1960s as the primary advisor and strategist of the SNCC.

Baker has been called “one of the most important American leaders of the twentieth century and perhaps the most influential woman in the civil rights movement.” She is known for her critiques not only of racism within American culture, but also of sexism within the civil rights movement.
