His debut picture book, The Sleepy Owl, was published by NorthSouth in 1986, but his big breakthrough came six years later with The Rainbow Fish. Marcus has illustrated over sixty-five books that have been translated into more than sixty languages and received countless international awards. He lives with his wife, Debora, and their children in Bern.
