Abstract
Four close colleagues reflect on Stuart T. Hauser's legacy to developmental psychology, adolescent psychiatry, and psychoanalytic research. Peter Fonagy highlights Hauser's unique contribution to the science of resilience. Alan Jacobson reflects on Hauser's groundbreaking investigations of the psychosocial dimensions of juvenile diabetes. Robert McCarley discusses Hauser's remarkable record of mentorship, and David Reiss poignantly captures defining qualities of Hauser's life that enabled his scientific contributions, and his gifts of mentorship and friendship. Together, these articles underscore the extraordinary breadth and depth of Hauser's influence on the science of understanding adolescents' interpersonal and intrapsychic journeys toward adulthood.
