According to Wikipedia: "Anna Sewell (30 March 1820 – 25 April 1878) was a British writer, best known as the author of the classic novel Black Beauty…. Her only publication was Black Beauty, which she wrote between 1871 and 1877 having moved to Old Catton, a village outside the city of Norwich in Norfolk. During this time her health was declining. She was often so weak that she couldn't get out of bed and writing at all was a challenge. She dictated the text to her mother and from 1876 began to write on slips of paper which her mother then transcribed. Anna Sewell sold the novel to the local publishers Jarrolds for £40 on 24 November 1877, when she was 57. Although now considered a children's classic, she originally wrote it for those who worked with horses. Anna said "It's a special aim being to induce kindness, sympathy, and an understanding treatment of horses."
