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".
Mary and Conrad Buff
Mary Buff (April 10, 1890 – 1970) and Conrad Buff II (August 31, 1886 – March 11, 1975) were married creators of illustrated children's books. Between 1937 and 1968, they collaborated on both text and illustrations to produce 14 books; four times they were a runner-up for the Caldecott Medal or Newbery Medal. They had a profound impact on children's literature in the middle of the 20th century.
