HISTORY OF THE TRAY
In 1929, Margaret Lowenfeld, a child psychiatrist, began to work with her patients by having them manipulate miniatures in a tray partially filled with sand. She called it The World Technique. The method appealed especially to an associate of Carl Jung’s, Dora Kalff. One of the many things that Jung is famous for is understanding the healing powers of the imagination. Kalff used her Jungian background to bring a new clinical dimension to interpreting and using Sandplay, which is a term created by Kalff to differentiate her Jungian-oriented technique from Lowenfeld’s.
