The Secret Language of Birthdays

Gary Goldschneider began his study of human personality with an interest in biographies and psychoanalytic theory. Before deciding against a career in medicine, for three years he attended Yale Medical School, where he studied psychiatry. During this time he discovered his deep and abiding interest in astrology and its symbolic relationship to personality.
