This book presents a series of informal biographies about major figures in the history of psychology. A unique combination of expertise and human appeal, the volume places the contributions of each pioneer in a new and fascinating perspective. For instance, several of the authors use the novel approach of having the pioneers return to the present day to reflect back on their work as it relates to the here and now. Revisions of speeches given in a popular series of invited addresses at psychological conventions, the chapters offer appealing glimpses into the lives of individuals who made a difference in the early years of psychology as a field of study. Each of the five volumes in this series contains different profiles thereby bringing more than 100 of the pioneers in psychology more vividly to life.
