One of the most profound writers to follow Jung in the field of Analytical Psychology, Marie-Louise von Franz was born in Munich in 1915 and earned a Ph.D. from the University of Zurich. She began analysis with Jung at eighteen, and worked with him on research until his death in 1961. Her first major publication, Aurora Consurgens, is the companion volume to Jung’s last major work, Mysterium Coniunctionis.
