Nicholas Hobbs (1915–1983).

Presents an obituary for Nicholas Hobbs. Just at the end of his stellar career of public service through psychology, Nick Hobbs received very appropriate honors showing that psychologists and many others knew what a precious national resource his life had been. Only days before his death from cancer on January 23, 1983, he participated in the dedication of the Nicholas Hobbs Laboratory of Human Development of the Peabody College for Teachers of Vanderbilt University, part of the Kennedy Center for Research on Education and Human Development that he founded and directed at its beginning. Two years earlier, he had received two parallel American Psychological Association (APA) awards--one for Distinguished Contributions to Psychology in the Public Interest and another for Distinguished Professional Contributions "utilizing psychological knowledge in the public interest and social policy." As the citations and testimonials on these occasions variously noted, Nick gave creative, responsible, and effective service to the institutions that he helped administer, to the Southern region from which he sprang, to the APA, and to the profession of psychology, but above all to the nation's children and youth, especially those who grew up with disadvantage and difficulty.
