"David Pilkey, who is also known by the pen name, Sue Denim was born on 4th March, 1966 is a very famous and renowned American writer and illustrator of children’s literature. He is most popular for being both the author and illustrator of the Captain Underpants book series. He occasionally also uses the pen names of George Beard and Harold Hutchins. Pilkey resides with his wife, Sayuri near Seattle, Washington. His father’s name was David Pilkey and mother’s name was Barbara. He also has one older sister whose name is Cindy. While Pilkey was in elementary school in Elyria, Ohio, he was diagnosed with and suffers from dyslexia and attention deficit hyperactivity disorder. He was therefore chided for his behaviour in school several times and consequently took to sitting at a desk in the school hall, where he fantasized and created the character of Captain Underpants. Pilkey gave his book, World War Won for entry in a national competition for student authors and won the prize in his age bracket. As a result of the award, the book was published in 1987."
