Final answer:
Rene Paul Chambellan designed both the Caldecott and Newbery Medals, with the Newbery established in 1921 and the Caldecott in 1937, both awards honoring significant contributions to children's literature.
Step-by-step explanation:
The Caldecott and Newbery Medals were both designed by renowned sculptor Rene Paul Chambellan. The Newbery Medal was designed in 1921 and the Caldecott Medal was designed later, in 1937. Originally, these awards were established to recognize and honor outstanding contributions to children's literature: the Newbery for written work and the Caldecott for illustrations.
The Newbery Medal depicts a figure of a man offering a book to a boy and a girl, who are both reaching out to receive it. This symbolism represents the transmission of knowledge and literature from one generation to the next. The Caldecott Medal features an image of a man on a horse in a parade, telling a story to a child, signifying the legacy and importance of storytelling and illustrations.
