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.
Robert McCloskey
McCloskey won a second Caldecott Medal in 1958 for "Time of Wonder". Meanwhile, he had been a runner-up in 1949 for "Blueberries for Sal", in 1953 for "One Morning in Maine", and in 1954 for "JourneyCake, Ho!", the latter written by his mother-in-law Sawyer. In a 1958 magazine article titled "Bob McCloskey, Inventor", another Medal winner Marc Simont observed that "[his] talent for devising mechanical contraptions is topped only by his ability to turn out books that carry off the Caldecott Medal."
