“Arnold Stark Lobel (May 22, 1933–December 4, 1987) was a popular American author of [pre-school-age] children’s books. Among his most popular books are those of the Frog and Toad series, and Mouse Soup, which won the Garden State Children’s Book Award from the New Jersey Library Association. Lobel won the 1981 Caldecott Medal for his book Fables.” (from Wikipedia, the free encyclopedia)
Lobel used alliteration and detailed imagery to bring his animals to life; although his illustrations were anthropomorphized, with Owls in bathrobes and Toad and Frog using vehicles to travel in, his colors are earthy and pastel, giving both a realistic and fantastic feel to his art.
Lobel also illustrated the works of other authors, for example Nathaniel Benchley, Charlote Zolorow, Jean van Leeuwen, Edward Lear. Lilian Moore, Peggy Parish, Jack Prelutsky as well as using other illustrators to illustrate his books.
