Another collaborator was Violette de Mazia (1896–1988), who was born in Paris and educated in Belgium and England. Originally hired to teach French to the Foundation staff in 1925, de Mazia became a close associate of Barnes, teaching and co-authoring four Foundation publications. After Barnes' death, she became a trustee and the Director of Education of the Art Department, continuing to express Barnes' philosophy in her teaching. The Violette de Mazia Foundation was then established after her death, and in 2011 the Barnes Foundation came to an agreement with them to allow the de Mazia Foundation student access to the collection for art education after its move to the Parkway. In 2015 however, the de Mazia Foundation ceased its operations and was absorbed by the Barnes Foundation.
