As [William] Valentiner noted in his uncompleted memoirs [Diego] Rivera’s [ ] murals rooted the Detroit Institute of Arts to the many-faceted jewel of its central court because of the harmonious, fertile relationship between "the industrialist" and "the artist." Rivera remarked to Valentiner how especially struck he was that "Edsel had none of the characteristics of the exploiting capitalist, that he had the simplicity and directness of a workman in his won factories and was like one of the best of them." Their relationship was like the murals themselves, a superb expression of pluralism, toleration, and empathy for the other, and of a cosmopolitan sense of all the Americas, not just of the United States of America or Detroit alone.
