Nikki Giovanni called Margaret Walker “the most famous person nobody knows.” This biography aims to correct that imbalance. Walker’s inner life was marked by bouts of poor health and a difficult marriage that stand in sharp contrast to her public persona, which revealed only lively intellectual engagement and deep commitment to the radical political forces at work during her lifetime (communism in the 1930s, and Black nationalism in the 1960s, both of which merged into her brand of humanism). This biography also reveals her connection to an even longer history as she took up the cause of educational reform, a mission that had motivated her parents in their lifetime. She is perhaps best known for her novel Jubilee from 1966, a historical narrative based on her maternal grandmother’s memories. Scholars often view the novel as a Black writer’s response to America's problematic fascination with Gone with the Wind (1936). The novel has enjoyed tremendous popularity, despite some scandal after Walker accused Alex Haley of plagiarism. Throughout her life Walker had an astonishing series of relationships with other writers, artists, and activists—Langston Hughes, Richard Wright, Ralph Ellison, Fannie Lou Hamer, Ruby Dee, Myrlie Evers, and Sonia Sanchez among them. She was the only member of her generation to insist upon living in the South and she had a full and sometimes chaotic home life. The resulting career slumps contrasted with her driven-ness as an unacknowledged intellectual and cultural force in the twentieth century. In these respects her biography is a portrait of the shifts between exceptional and everyday life—a tension that rippled across Walker’s eighty-three and informed her unique view of the world.
