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".
John Schoenherr
John Carl Schoenherr (July 5, 1935 – April 8, 2010) was an American illustrator. He won the 1988 Caldecott Medal for U.S. children's book illustration, recognizing "Owl Moon" by Jane Yolen, a father-and-daughter story where only Schoenherr's drawings reveal the child's gender. He was posthumously inducted by the Science Fiction and Fantasy Hall of Fame in 2015.
