Told in the first person as if written by Beautiful Jim himself, this is the story of the sensation in the late 1800s and early 1900s: a horse whose owner, Doc Key, a formerly enslaved man who loved animals, taught to read, write, and do math. Reading Jim's diary and the story, we learn how, together with Doc Key, Jim performed all over the United States, even for two presidents, while promoting kindness to animals.
