This volume provides a wide-ranging narrative, through the work of an exceptional public servant, of the 20th century development of water and environmental planning.  It  illuminates how a single active individual in government service can have a significant impact on transforming new academic principles into accepted planning practice.  Harry E. Schwarz was the first practitioner in a major Federal agency to adopt and implement many of the new ideas and methods of water resources and environmental planning pioneered by Professors Arthur Maass and Gilbert White, for whom  the Maass-White Library Series in Water Planning and Management  is named. This book makes available a substantial selection of Schwarz's innovative work, which can provide guidance and encouragement to today's planners and researchers as they confront the new challenges of our time. This book will appeal to government planners in water resources and the environment, to professionals in the private sector, and to faculty and graduate students in a range of programs dealing with natural resources planning.
