Ending an often testy and sometimes distant 25-year coexistence, the Barnes Foundation will merge with the foundation established by the estate of Violette de Mazia, Albert C. Barnes' longtime colleague.

The Violette de Mazia Foundation - whose sole purpose has been to promulgate and support art education based on the formalist pedagogical principles of Barnes, de Mazia, and the philosopher John Dewey - will form the core of the Barnes-de Mazia Education Program, to be based at the Barnes Foundation on the Parkway.
