Launched in 1971, Adolescent Psychiatry, in the words of founding coeditors Sherman C. Feinstein, Peter L. Giovacchini, and Arthur A. Miller, promised "to explore adolescence as a process...to enter challenging and exciting areas that may have profound effects on our basic concepts."  Further, they promised "a series that will provide a forum for the expression of ideas and problems that plague and excite so many of us working in this enigmatic but fascinating field."  For over two decades, Adolescent Psychiatry has fulfilled this promise.  The repository of a wealth of original studies by preeminent clinicians, developmental researchers, and social scientists specializing in this stage of life, the series has become an essential resource for all mental health professionals working with youth.
Volume 20 of the series serves as a tribute to editor emeritus Sherman C. Feinstein.  In addition to an appreciation of, and contributions by, Dr. Feinstein, it contains heretofore unpublished papers by two other major figures in adolescent psychiatry, founding father William Schonfeld and a Viennese colleague transplanted to America, Siegfried Bernfeld.  With sections on general considerations of adolescence, specific syndromes, and treatment modalities, volume 20 presents the work of many of today's preeminent minds in adolescent psychiatry.
