Lowenfeld Mosaics, 1999.
© Science Museum / Science & Society Picture Library
This set of 556 small plastic tiles, in five geometric shapes and six primary colours, was based on a set designed in the 1930s and used by the psychologist Margaret Lowenfeld (1890-1973) in her psychotherapy of adults and children. Lowenfeld was a paediatrician who became a pioneer of child psychology and psychotherapy. She recognised that language is often unsatisfactory as an expresive medium for children and that play is an esential part of their development. She consequently invented non-verbal techniques to enable them to convey their experiences. Her mosaics used tiles of different colours and shapes to produce a powerful diagnostic and therapeutic instrument.
