MUNRO LEAF (1905–1976) was an American writer, illustrator, and columnist whose books for children include Manners Can Be Fun and How to Behave and Why (both of which he also illustrated). In 1936 he “dashed off in 25 minutes” a story about a bull who preferred flowers to bullfights as a showcase for the artistic talent of his friend Robert Lawson. The Story of Ferdinand went on to become a best-seller and the two men collaborated on three subsequent books, Wee Gillis (1938), The Story of Simpson and Sampson (1941), and Aesop’s Fables (1941).
 
ROBERT LAWSON (1892-1957) was a prolific writer and illustrator of literature for children and was the first person ever to receive both the Newbery and Caldecott medals. Among his forty-odd books are such classic stories as Rabbit Hill, Ben and Me, and They Were Strong and Good.
