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".
Katharine Burr Blodgett Medal and Prize
At its inception in 2008, the award was named the "Business and Innovation Medal". In 2012, it was renamed the "Swan Medal and Prize" in memory of Sir Joseph Swan, a chemist, physicist, and early developer of the incandescent light bulb. Since 2016, the award was renamed again to commemorate Katharine Burr Blodgett, inventor of low-reflectance invisible glass and the first woman to receive a degree in physics from Cambridge University.
