Black Beauty: His Grooms and Companions, the Autobiography of a Horse is an 1877 novel by English author Anna Sewell. It was composed in the last years of her life, during which she was bedridden and seriously ill. The novel became an immediate best-seller, with Sewell dying just five months after its publication, but having lived long enough to see her only novel become a success. With fifty million copies sold, Black Beauty is one of the best-selling books of all time.
