Wake up, bear - it's Christmas!

Stephen Gammell (born February 10, 1943) is an American illustrator of children's books. He won the 1989 Caldecott Medal for U.S. picture book illustration, recognizing Song and Dance Man by Karen Ackerman. His illustrations in Where the Buffaloes Begin by Olaf Baker (1982) and The Relatives Came by Cynthia Rylant (1986) earned those titles the designation of Caldecott Honor books. Although he is most widely known for his evocative, nightmarish illustrations for Alvin Schwartz's Scary Stories to Tell in the Dark trilogy, he has illustrated nearly seventy books between 1973 and 2013, including nine which he authored himself.
