Andrew Clements has written a number of books for children, including three novels about school life. He taught in public schools near Chicago for seven years before moving east to begin a career in publishing. The idea for Frindle grew out of a talk that he gave to second graders. He says that "Frindle is about discovering the true nature of words, language, thought, community and learning, and about the life that surges through the corridors and classrooms every day." Andrew Clements now writes full-time and lives in central Massachusetts with his wife and their four children.

Tim Bowers began his illustrating career working as an artist for Hallmark Cards. In 1986 he illustrated his first picture book, The Toy Circus by Jan Wahl. Since then, he has illustrated more than twenty books for children. Mr. Bowers lives with his family in Granville, Ohio.
