ALS in German, signed “C. G. J.,” penned on both sides of a 4 x 5.75 postal card that is postmarked at Bollingen, Switzerland, on January 2, 1929. An untranslated handwritten letter to his colleague, Dr. Wolfgang M. Kranefeldt, that regards a speech. In fine condition.



Kranefeldt was a German psychiatrist, psychotherapist, and National Socialist (1892-1950) who was closely associated with Carl Jung. He was active in the AAGP and IAAGP in the 1930s and in 1936 joined the faculty of the Göring Institute in Berlin. He was regarded as Jung's ‘leading pupil in Germany. In 1934, Kranefeldt published the book Secret Ways of the Mind: A Survey of the Psychological Principles of Freud, Adler, and Jung. The work features an introduction by Jung, which to this day offers great into his reassessment of psychoanalysis.



The village of Bollingen on the shore of the Obersee (upper lake) basin of Lake Zürich is home to the Bollingen Tower, an inhabitable two-story stone structure that Carl Jung began building in 1923. Additions to the tower were constructed in 1927, 1931, and 1935, resulting in a building that has four connected parts. Another story was added to the 1927 addition after the death of Jung's wife in 1955, signifying ‘an extension of consciousness achieved in old age.’ For much of his life, Jung spent several months each year living at Bollingen.
