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".

He was the son of Alexander Meadows Rendel and the nephew of Stuart Rendel. Her mother, Ruth Frances "née" Paul, was the daughter of the publisher Kegan Paul. Leila was the eldest of three siblings. Her sister, Olive, became an obstetrician and later wrote a book on the use of exercise in the post-war rehabilitation of children. Her brother, Robert, became a stage and film actor.
