Two sisters, two cases of C.G. Jung : the story of two patients and their relation to Jung's evolving practice

This research conducts an investigation of Maggy Reichstein and Mischa Epper, two unknown cases of C.G. Jung, around the 1920s. The sisters belonged to an aristocratic family and Reichstein, born in Indonesia in 1894, brought her sister Epper, born in Holland in 1901, to Zürich to be treated in 1917. Epper’s story sheds light on an important period of the development in Jung’s practice. Her story adds information to the manner in which Jung applied and taught the techniques he developed in his self-experiment. Epper’s case also sheds light on the work of Maria Moltzer, one of Jung’s early close collaborators. Jung mentioned, anonymously, Reichstein's case as an example in different passages in his presentations and writings, relating it to the process of transference and countertransference, to the concept of synchronicity, and to his studies on Eastern psychology. He published some of her mandalas, and considered her able to understand his ideas in depth. Reichstein’s case challenged and triggered his interests in different subjects. The material presented can be compared to Jung’s treatments of Kristine Mann, Tina Keller-Jenny and Christiana Morgan, which took place in a similar period of time. The research also provides insights into how Jung shaped case material as examples for his concepts.
