Acknowledgements
1The authors would like to acknowledge those who worked with Medard Gabel on an earlier version of this book, including Robert Blissmer, Howard Brown, Robert Cook, Geoffrey Hoare, Cathy Horvitz, Jack Ren Marquette, and Gail Ziegelmeier. That book, the Environmental Design Science Primer, now almost fifty years old and seriously out of date, nevertheless served as an organizational inspiration for this document. The authors of this present volume thank those whose work inspired us.
