Arnold Stark Lobel (May 22, 1933 – December 4, 1987) was an American author of children’s books, including the Frog and Toad series and Mouse Soup. He both wrote and illustrated those picture books, as well as Fables, for which he won the 1981Caldecott Medal recognizing the year’s best-illustrated U.S. picture book. He won a Newbery Honor Award in 1973 for Frog and Toad Together.
Lobel felt his personality was reflected in the two characters, saying “Frog and Toad are really two aspects of myself.” The marked contrast between adventurous Frog and bumbling Toad is part of what made their relationship believable and endearing. He loved his work, saying “I cannot think of any work that could be more agreeable and fun than making books for children.” Lobel illustrated close to 100 books during his career, which were translated into dozens of languages.
