Hannah began analysis with Jung in 1929. She befriended
Joseph L. Henderson the same year, and shared accommodation with him in Zurich. In late 1974, she accepted
Marion Woodman into analysis stating, "You are a parson's daughter; I am a parson's daughter...Jung told me that only a parson's child can handle a parson's child.' Hannah became a close friend of Swiss
Jungian psychologist Marie-Louise von Franz, to whom she was introduced by Jung. He encouraged the younger von Franz to live with her, stating that "the real reason you should live together is that your chief interest will be analysis and analysts should not live alone." Hannah wrote a biography of Jung entitled
Jung, His Life and Work: A Biographical Memoir. She also practised as a
psychotherapist and served as
lecturer at the
C.G. Jung Institute. ==Major works==
