Austrian psychiatrist and psychotherapist who developed the psychological approach known as logotherapy, widely recognized as the “third school” of Viennese psychotherapy, after the “first school” of Sigmund Freud and the “second school” of Alfred Adler. The basis of Frankl’s theory was that the primary motivation of an individual is the search for meaning in life and that the primary purpose of psychotherapy should be to help the individual find that meaning.
