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.
Kate Greenaway Medal
Gail E. Haley was the first illustrator to win both medals, albeit for different works: the 1971 Caldecott for "A Story a Story" (1970) and the 1976 Greenaway for "The Post Office Cat". She also wrote both books.
