Bruce Coville was born in Syracuse, New York, on May 16, 1950. He spent one year at Duke University in North Carolina. Coville started working seriously at becoming a writer when he was seventeen. He was not able to start selling stories right away, so he had many other jobs, including toymaker, gravedigger, cookware salesman, and assembly line worker. Eventually, Coville became an elementary teacher, and worked with second and fourth graders. Coville married Katherine Dietz an artist, and they began trying to create books together. It wasn't until 1977 that they finally sold their first book, The Foolish Giant. They joined together on two other books after that, Sarah's Unicorn and The Monster's Ring, and followed them with Goblins in the Castle, Aliens Ate My Homework, and The World's Worst Fairy Godmother.
