Marie Louise Von Franz (4 January 1915 – 17 February 1998), was C.G. Jung’s perhaps most trusted colleague. She lived with another of Jung’s colleagues, Barbara Hanna:
“In the autumn of 1946 Jung suggested that Marie-Louise von Franz and Barbara Hannah should move into a shared apartment. He argued that it was better for unmarried people to live in one household to experience all the good as well as the bad times of a closer relationship and therewith become better analysts.
For 25 years, until Barbara Hannah’s death, they lived together at Lindenbergstrasse 15 in Küsnacht and in the Tower in Bollingen, that Marie-Louise von Franz had built in 1958.” (https://www.psychologyclub.ch/…/archive/barbara-hannah)
