Jerry Saltz at New York Magazine:
In 1953, Walter and the love of his life Eileen Galway set sail to London for a planned ten-year European Grand Tour: nothing but love, ambition, and promise was on the horizon. Yet by the time he died, in 2009, he had spent the last two decades of his life living alone, dirt-poor, in a shack without running water, electricity, or access to roads, on the side of an Antigua mountain. Here, rocketing between brilliant insight, wild imagination, full-on hallucination, and fits of delusional grandeur he produced an epic series of almost entirely unseen work — including a 25,000-page typed manuscript on philosophy, history, art, geology, and biology; numerous plays, poems, musical scores; and hundreds of hours of recorded audiotape. He also made over 5,000 sculptures, paintings, drawings, diagrams, cosmic charts, and heraldry designs on cardboard, wood panels, old photos, the backs of album covers, paper bags, planks, metal signs, and any surface he could scavenge. (All of this would likely have been lost were it not for art historian Barbara Paca happening upon his work in Antigua at the very end of Walter’s life, and seeing genius. In 2017, Paca oversaw Walter being named the representative of Antigua and Barbuda at the Venice Biennale.)
