William Still’s parents escaped slavery but had to leave two of their children behind, a tragedy that haunted the family. As a young man, William went to work for the Pennsylvania Anti-Slavery Society, where he raised money, planned rescues, and helped freedom seekers who had traveled north. And then one day, a strangely familiar man came into William’s office, searching for information about his long-lost family. Could it be? Motivated by his own family’s experience, William began collecting the stories of thousands of other freedom seekers. As a result, he was able to reunite other families and build a remarkable source of information, including encounters with Harriet Tubman, Henry Box Brown, and William and Ellen Craft. Award-winning author-illustrator Don Tate brings to life the incredible, stranger-than-fiction true story of William Still, a man who dedicated his life to recording the stories of enslaved people fleeing to freedom. Tate’s powerful words and artwork are sure to inspire young audiences in this biography of the Father of the Underground Railroad.
