Harriet Tubman

Harriet Tubman (born Araminta Ross; c. 1822 – March 10, 1913) was an African-American abolitionist, humanitarian, and, during the American Civil War, a Union spy. Born into slavery, Tubman escaped and subsequently made some thirteen missions to rescue approximately seventy enslaved families and friends,^[2] using the network of antislavery activists and safe houses known as the Underground Railroad. She later helped abolitionist John Brown recruit men for his raid on Harpers Ferry, and in the post-war era was an active participant in the struggle for women's suffrage.
