As a child, Dav Pilkey was diagnosed with dyslexia and ADHD. Dav was so disruptive in class that his teachers made him sit out in the hall every day. Luckily, Dav loved to draw and make up stories, so he spent his time in the hallway creating his own original comic books. In the second grade, Dav Pilkey created a comic book about a superhero named Captain Underpants. He has gone on to write and illustrate many award-winning and bestselling books for children. His Captain Underpants series has tens of millions of copies in print worldwide and has been translated into more than two dozen languages. In 2017, DreamWorks Animation brought the character to the silver screen in the feature film adaptation Captain Underpants: The First Epic Movie, and Netflix is now streaming The Epic Tales of Captain Underpants TV show. Dav’s latest creation, Dog Man, continues to be a #1 New York Times bestselling series with translations available in more than 35 languages. Dav is also the author and illustrator of the The Paperboy (which is a Caldecott Honor Book), the Dragon series, Dog Breath, ’Twas the Night Before Thanksgiving, and the Dumb Bunnies series.
