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".
Berta and Elmer Hader
Berta Hoerner Hader (August 1, 1890 – February 6, 1976) and Elmer Stanley Hader (September 7, 1889 – September 7, 1973) were an American couple who jointly illustrated more than 70 children's books, about half of which they also wrote. They won the annual Caldecott Medal for "The Big Snow" (1948), recognizing the year's "most distinguished American picture book for children". They received the Caldecott Honor Book Award for "Cock-a-doodle-doo" in 1940 and "The Mighty Hunter" in 1944.
