Born free in 1821 to two parents who had been enslaved, William Still was drawn to antislavery work from a young age. Hired as a clerk at the Anti-Slavery office in Philadelphia after teaching himself to read and write, he began directly assisting enslaved people who were crossing over from the South into freedom. Andrew Diemer captures the full range and accomplishments of Still's life, from his resistance to Fugitive Slave Laws and his relationship with John Brown before the war, to his long career fighting for citizenship rights and desegregation until the early twentieth century.
