Dora Kalff (1904–1990) was a Swiss Jungian therapist who developed Sandplay Therapy, a powerful non-verbal therapeutic method that helps both children and adults access their inner world. 

 

The basis of Sandplay includes the depth psychology of Carl Jung and Kalff was encouraged by him to develop a method that could help children express their unconscious.  It was then discovered that adults also benefitted imensely from Sandplay.

 

The Sandplay method created by Dora Kalff included Margaret Lowenfelds "World Technique" serving as the primary foundation for the use of sandtrays and miniatures.

 

Kalff uniquely integrated principles from Eastern philosophy, particularly Zen and Tibetan Buddhism, which informed her focus on the therapist's role as a "silent witness".

 

 In 1985, she founded the International Society for Sandplay Therapy (ISST) to preserve and spread her teachings worldwide
