Roger Antoine Duvoisin (August 28, 1900 – June 30, 1980)[1] was a Swiss-born American writer and illustrator best known for children's picture books.
He won the 1948 Caldecott Medal for picture books[2] and in 1968 he was a highly commended runner-up for the biennial, international Hans Christian Andersen Award for children's illustrators.
He also became a manager of an old French pottery plant before becoming involved with textile design, an occupation that eventually brought him to the United States.
He sometimes gave 1904 as his year of birth but he was nearly 80 at his death, born in 1900—the US Library of Congress learned from a publisher, indirectly from his widow.
Duvoisin's works also include translation and illustration of medieval European folk tales such as The Crocodile in the Tree (1973).
