In Step Right Up: How Doc and Jim Key Taught the World About Kindness, author Donna Janell Bowman tells how a former slave and his horse changed people's ideas about how animals learn. Doc Key trained his horse, Beautiful Jim Key, with treats instead of beatings. Using this method, Beautiful Jim Key learned how to count, add, read, and write. Doc took Jim on the road to perform all over the United States, even for President McKinley! Everywhere they went, Doc Key encouraged people to sign a pledge, promising to treat all animals with kindness.
