Randolph Caldecott
Randolph Caldecott (; 22 March 1846 – 12 February 1886) was an English artist and illustrator, born in Chester. The Caldecott Medal was named in his honour. He exercised his art chiefly in book illustrations. His abilities as an artist were promptly and generously recognised by the Royal Academy. Caldecott greatly influenced illustration of children's books during the nineteenth century. Two books illustrated by him, priced at a shilling each, were published every Christmas for eight years.
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.
