Today, Harriet Tubman is an icon for the struggle for freedom in the United States. Her story might have been lost to history except for one woman, Sarah Bradford, who agreed to write her friend's biography. But who was she? Why did she say, "Yes," when others called her plan to make a heroine of a black woman and slave a "quixotic attempt," doomed to failure from the start. Working together, these two indomitable women, one born a slave and a hero of the Civil War, the other born into a privileged New York family, gave voice to their shared vision of the New Republic. Little has been known of the remarkable Sarah Bradford. Until now.
