Korman wrote his first book, "This Can't be Happening at Macdonald Hall", when he was 12 years old, for a coach who suddenly found himself teaching 7th grade English. He later took that episode and created a book out of it, as well, in "The Sixth Grade Nickname Game", wherein Mr. Huge was based on that 7th grade teacher. Korman moved to New York City, where he studied film and film writing. While in New York, he met his future wife; they now live in Long Island with their three children. He has published more than 50 books.

The author of over 80 books in a little over a decade of writing, Dan Gutman has written on topics from computers to baseball. Beginning his freelance career as a nonfiction author dealing mostly with sports for adults and young readers, Gutman has concentrated on juvenile fiction since 1995. His most popular titles include the time-travel sports book Honus and Me and its sequels, and a clutch of baseball books, including The Green Monster from Left Field. From hopeful and very youthful presidential candidates to stunt men, nothing is off limits in Gutman's fertile imagination. As he noted on his author Web site, since writing his first novel, They Came from Centerfield, in 1994, he has been hooked on fiction. "It was fun to write, kids loved it, and I discovered how incredibly rewarding it is to take a blank page and turn it into a WORLD." Gutman was born in New York City in 1955, but moved to Newark, New Jersey the following year and spent his youth there.

Francesca Simon grew up in California and attended both Yale and Oxford Universities, where she specialised in Medieval Studies. How this prepared her to write children’s books she cannot imagine, but it did give her a thorough grounding in alliteration. She then threw away a lucrative career as a medievalist and worked as a freelance journalist, writing for the Sunday Times, Guardian, Mail on Sunday, Telegraph, and Vogue (US). After her son Joshua was born in 1989, she started writing children’s books full time. One of the UK’s best-selling children’s writers, Francesca has published over 50 books, including the immensely popular HORRID HENRY series, which has now sold over twelve million copies. Francesca won the Children’s Book of the Year in 2008 at the British Book Awards for Horrid Henry and the Abominable Snowman. HORRID HENRY is published in 24 countries and is also an animated CITV series. She lives in London with her husband, son, and Tibetan Spaniel, Shanti.
