In 1908, Barnes organized his business, the A.C. Barnes Company, as a cooperative, devoting two hours of the work day to seminars for his workers. They read philosophers William James, Georges Santayana, and John Dewey. Barnes also brought some of his art collection into the laboratory for the workers to consider and discuss. This kind of direct experience with art was inspired by the education philosophy of John Dewey and planted the seed that eventually grew into the establishment of the Barnes Foundation. The two met at a Columbia University seminar in 1917 becoming close friends and collaborators spanning more than three decades.
