Marcus Pfister was born in Bern, Switzerland. After studying at the Art School of Bern, he apprenticed as a graphic designer and worked in an advertising agency before becoming self-employed in 1984. His debut picture book, The Sleepy Owl, was published by NorthSouth Books in 1986, but his big breakthrough came six years later with The Rainbow Fish. Today Marcus has illustrated over fifty books, which have been translated into more than fifty languages and received countless international awards. He lives with his wife, Debora, and his children in Bern.
"An award winning series, "The Adventures of Rainbow Fish" teaches children not only about fish and marine dwellers, but also such values as working together to solve problems, valuing each others unique differences, and using creativity to make up with friends who are different instead of fighting with them."- Midwest Book Review
