I've always been irked by the lack of recognition Glackens has received in the formation of the Barnes Foundation. Glackens was the real discoverer of Renoir for America, not Barnes. Glackens studied the works of Manet, Renoir, Degas, and other French Impressionists when they were actually cutting edge artists. Barnes provided the money to amass the collection, but the real visionary of the Barnes Foundation is William Glackens, at least in my mind. The Barnes Foundation in Lower Merion includes a room of Glackens' work, but too many people rush through to see all the Renoir and Matisse, unfortunately.
Perhaps one day William Glackens will be remembered as one of the pioneers of American Impressionism, but not soon enough for me.
