The Caldecott Medal is awarded annually to the children’s book whose illustrations represent the best work being produced in the field of children’s book illustration. This honor is the highest award in the nation for children’s illustrators, for which even a nomination is considered a remarkable achievement. Throughout the years, most illustrators have only won one award, with several winning two. However, only two illustrators, since the conception of the award, have won the medal three times. Those two artists are Marcia Brown, and today’s subject of our Caldecott Winning Illustrators series: David Wiesner.
