David

Best known for his books chronicling the adventures of "Captain Underpants," Dav Pilkey has built a reputation as one of his generation's most inventive writers and illustrators. Yet as a young boy, he seemed unlikely to ever become a success. Suffering from attention-deficit/hyperactivity disorder, or ADHD, this one-time "class clown" was sent out from class to sit in the hallway so often that he had his own desk waiting for him, which he kept stocked with paper, pencils, and crayons.
