On March 30, 1820, Anna Sewell was born into a devoutly Quaker family. Her mother, Mary Wright Sewell, was a successful children's book author. Sewell was mostly educated at home and did not attend school for the first time until she was twelve years old. Two years later, she seriously injured both ankles in an accident. From then on, Sewell had extremely limited mobility; she required crutches and could never walk great distances.
