I am seeking information for an upcoming book on the artsit William E.B. Starkweather who painted with Twachtman and Sorolla and lived next door to Hopper. Starkweather had a museum in Endless Caverns, Virginia for 30 years. We need ephemera, stories about his life and paintings that have survived. The Metropolitan Museum is using a Starkweather painting from their collection in the 2011 New York Calendar.
