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".
Alice and Martin Provensen
The Provensens were a runner-up for the 1982 Caldecott Medal as illustrators of "A Visit to William Blake's Inn" by Nancy Willard (who won the companion Newbery Medal). Two years later they won the Caldecott for "The Glorious Flight", the story of aviator Louis Blériot, the first man to fly solo across the English Channel, which they also wrote. The annual award by U.S. professional librarians recognizes the year's "most distinguished American picture book for children". Eight of their books were named to "The New York Times" annual Ten Best Illustrated Books, including "Our Animal Friends at Maple Hill Farm" (1974) and "An Owl and Three Pussycats" (1981). The couple were collaborative illustrators for Donald Waxman's "Pagaents for Piano," a series of pedagogical primers.
