ABSTRACT
Jung encountered the sisters Mischa Epper and Maggy Reichstein during an important phase in the development of his ideas, namely, as he began to teach and apply the findings of his self-experimentation. The case of Mischa Epper sheds light on the historical development of the technique of active imagination. The notes of Epper’s diary showed the use of the technique of active imagination by Jung’s collaborator Moltzer, and, in this respect, it sheds light upon a phase when Jung’s technique was still in development. Conversely, Reichstein’s case gives us an example of how Jung used clinical material in his presentations. Comparing the available biographical information of Jung’s patients, and the use of primary sources in the two new cases, allows us to draw a better picture of Jung’s practice and his shaping of case material. This focus allows us a better understanding of how Jung used and framed clinical material in the context of his ideas, particularly in the way he presented his cases related to his postulations.
