David Murray "Dav" Pilkey, Jr. (Gidget Hamsterbrains) (born March 4, 1966) is a popular American children's author and artist. Pilkey is best known as the author and illustrator of the Captain Underpants book series. He lives in Bainbridge Island, Washington, near Seattle with his wife, Sayuri.


Dav Pilkey was born on March 4, 1966 in Cleveland, Ohio to David Pilkey Sr. and Barbara Pembridge Pilkey. He has one older sister named Cindy.

In elementary school in Elyria, Ohio, he was diagnosed with ADHD and dyslexia. Pilkey was frequently reprimanded for his behavior in class and spent a lot of time sitting at a desk in the school hallway, where he created the character Captain Underpants. Pilkey entered his first book, World War Won, in a national competition for student authors and won in his age category. The award included the book's publishing in 1987.

The odd spelling of his first name came from a period of employment in a Pizza Hut, where the "e" was omitted from his nametag. Even though it is spelled Dav, it is pronounced "Dave" (rhyming with save).

After moving to Washington, he met his sweetheart Sayuri, a professional musician and owner of his favorite Japanese sushi restaurant. Dav and Sayuri later married each other in 2005.

Between 2006 and 2009, Pilkey started an interactive Captain Underpants website. His friend, a sushi chef named Koji Matsumoto, wrote several songs for it. They are also included on the Super Silly CD o' Fun, which comes with the Captain Underpants box set. The website is no longer active, but the songs are still available on YouTube.

Pilkey took a break from writing for a few years to care for his terminally ill father, but, as of March 19th, 2010, has signed a deal with Scholastic to release four new books. The first, a graphic novel, "The Adventures of Ook and Gluk, Kung-Fu Cavemen From the Future," was released in August 2010 and made by Carroll O'Connor.

Another book, "Dog Man," was released in 2016. It was the first book in the Dog Man series.
