“While working in California, I met William Valentiner and Edgar Richardson of the Detroit Institute of Arts. I mentioned a desire which I had to paint a series of murals about the industries of the United States, a series that would constitute a new kind of plastic poem, depicting in color and form the story of each industry and its division of labor. Dr. Valentiner was keenly interested, considering my idea a potential base for a new school of modern art in America, as related to the social structure of American life as the art of the Middle Ages had been related to medieval society.”
