Anna Sewell was born in 1820 in England. Around the age of 14, Sewell fell and injured her ankles. They didn't heal properly. From then on, she had trouble walking and relied on horses to take her where she needed to go. She loved horses and was grateful for them. Sewell was shocked to see how cruelly some people treated her favorite animal. In 1872, Sewell was told she had only a short time to live. She decided to write a book that would show the kind and loving nature of horses. That book, the only one she ever wrote, was Black Beauty. It has been considered a classic since it was published in 1877.
