Henry Murray

Henry Alexander Murray was an American professor of psychology at Harvard University who, despite having no formal training in psychology, made several notable contributions to the field, including a personology theory of personality. With Christiana Morgan he co-developed the Thematic Apperception Test, a widely used projective measure of personality. In his later years at Harvard, from 1959 to 1962, Murray led a series of experiments studying how people's beliefs held up under extreme stress; the experiments, in which one participant was Ted Kaczynski, later known as the Unabomber, have since been recognized as likely unethical because of their psychologically damaging, deliberately abusive design and their use of deception.
