I read somewhere that Andrew Wyeth was outside once doing a watercolor. A couple people wandered over to peek. Wyeth overheard one tell the other that the painter was an amateur who didn't know anything about art. In the first volume of the Matisse biography, Spurling recounts that Matisse once met Madame Cezanne after her husband had died. She told Matisse that her husband had been an old fool who did not know anything about art.
