"Illiterate but deeply religious, Harriet Tubman was raised on the Eastern Shore of Maryland in the 1820s, not far from where Frederick Douglass was born. As an adolescent, she incurred a severe head injury when she stepped between a lead weight thrown by an irate master and the slave it was meant for. She recovered but suffered from visions and debilitating episodes for the rest of her life. While still in her early twenties she left her family and her husband, a free black, to make the journey north alone. Yet within a year of her arrival in Philadelphia, she found herself drawn back south, first to save family members slated for the auction block, then others. Soon she became one of the most infamous enemies of slaveholders. She established herself as the first and only woman, the only black, and one of the few fugitive slaves to work as a conductor on the Underground Railroad.
