Frederick Douglass was born into slavery in Maryland, 1818. He was separated from his mother as a baby and lived with his grandmother up to the age of eight, when he was sent to live as a house servant, a field hand and then a ship caulker. He escaped to New York in 1838 and seven years later published Narrative of the Life of Frederick Douglass, an autobiography of his life as a slave, which became an instant bestseller.

Douglass rose to fame as a powerful orator and spent the rest of his life campaigning for equality. He became a national leader of the abolitionist movement, a consultant to Abraham Lincoln in the civil rights movement and a passionate supporter of the women’s rights movement. He died in 1895.

Sojourner Truth (c.1797 - 1883) was born into slavery in New York State. In 1826, she escaped with her young daughter, leaving two of her other children behind. When her son was later illegally sold to a slave owner in Alabama she sued for his return, becoming one of the first black women to successfully challenge a white man in an American court. She spent the rest of her life campaigning for abolition, equal rights and universal suffrage, and found fame as a reformer and public speaker. Her memoir, The Narrative of Sojourner Truth, is published in Penguin Classics.
