Karlfried Graf Durckheim (1896-1988) was a German diplomat, writer, and psychologist of noble origin. During his diplomatic career in Japan, he deeply studied Zen Buddhism and Japanese culture, which profoundly shaped his later work. After World War II, he transitioned to psychoanalysis and founded the Georg Groddeck Institute in Munich. He became a key figure in integrating Eastern philosophy with Western psychology, making significant contributions to humanistic and transpersonal psychology. His works including 'The Way of Transformation' and 'Japan and the Spirit of the West' influenced generations of psychologists and spiritual seekers in the West.
