Jon Klassen is a Canadian writer and illustrator of children's books, and an animator. He is known for the 2012 picture book This Is Not My Hat, which won both the Caldecott Medal and the Kate Greenaway Medal. This Is Not My Hat is a companion to Klassen's preceding picture book, I Want My Hat Back (2011), which was his first as both writer and illustrator. Both books were on the New York Times Best Seller list for more than 40 weeks; by April 2014 one or the other had been translated into 22 languages and they had jointly surpassed one million worldwide sales. Both books were recommended for children ages 5+ by the Greenaway judges. Klassen's Hat Trilogy was completed with the publication of We Found a Hat (2016).
