Frederic G. Melcher
Melcher proposed the Caldecott Medal in 1937 to honor children's picture books. Named for British illustrator Randolph Caldecott, the medal is presented annually for the "most distinguished picture book for children".
Brian Selznick
Prior to winning the 2008 Caldecott Medal, Selznick had been a runner-up for the award, winning a Caldecott Honor in 2002 for "The Dinosaurs of Waterhouse Hawkins: An Illuminating History of Mr. Waterhouse Hawkins, Artist and Lecturer". Other awards include the Texas Bluebonnet Award, the Rhode Island Children's Book Award, and the Christopher Award.
