This book is dedicated to the memory of John J. and Emma L. Bonica. John was the inspiration and guiding force behind the pain movement that began with the first edition of this book; Emma made his contributions possible. We miss them both, but the momentum they created is rapidly accelerating, and the memories of their goodness will be with all who study pain and its management.
