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".
Gerhard Herzberg Canada Gold Medal for Science and Engineering
NSERC's Canada Gold Medal for Science and Engineering was first awarded in 1991 to Raymond Lemieux, a chemist working at University of Alberta. Mathematician James Arthur from the University of Toronto was the 1999 recipient, the last year before the award was renamed in honour of Gerhard Herzberg, the winner of the 1971 Nobel Prize in Chemistry. NSERC decided to rename the award after Herzberg because they felt he embodied the two main qualities of the award, namely research contributions that are of high quality and influential.
