This eleventh volume in the series departs from the pattern of earlier volumes. Some of those volumes addressed research, design, and policy topics in terms of environmental settings, for example, homes, communities, neighborhoods, and public places. Others focused on environmental users, for example, chil­ dren and the elderly. The present volume examines the field of environment and behavior studies itself in the form of intellectual histories of some of its most productive and still visible senior participants. In so doing we hope to provide readers with a grand sweep of the field-its research and design content, methodology, institutions, and past and future trajectories-through the experiences and intellectual histories of its participants. Why intellectual histories? Several factors led to the decision to launch this project. For one, 1989 was an anniversary and commemorative year for the Environmental Design Research Association, perhaps the major and most long-standing interdisciplinary organization of environment and behavior re­ searchers and practitioners. Established in 1969, this organization has been the vehicle for generations of researchers and practitioners from many disciplines to come together annually to exchange ideas, present papers, and develop professional and personal relationships. It held its first and twentieth meetings in North Carolina, with the twentieth conference substantially devoted to dis­ cussions of the past, present, and future of the field-a taking stock, so to speak. Thus it seemed appropriate to launch a volume on intellectual histories at this significant juncture in the life of the field.
