Caldecott Medal
The award is named for Randolph Caldecott, a nineteenth-century English illustrator. Rene Paul Chambellan designed the Medal in 1937. The obverse scene is derived from Randolph Caldecott's front cover illustration for "The Diverting History of John Gilpin" (Routledge, 1878, an edition of the 1782 poem by William Cowper), which depicts Gilpin astride a runaway horse. The reverse is based on "Four and twenty blackbirds baked in a pie", one of Caldecott's illustrations for the nursery rhyme "Sing a Song of Sixpence".
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.
