Blanche Morgan was a set and costume designer for the Seattle Negro Repertory Company, a subsidiary of the WPA's Federal Theater Project which put on plays with African-American actors. She was also a watercolor artist and interior designer for Frederick & Nelson. She studied at the University of Washington and was a member of Women Painters of Washington, Northwest Watercolor Society, and the National Association of Women Artists. Her art departed from the traditional attitudes of loose, whimsical images done with watercolor, concentrating more on crisp, precise form and design. She exhibited in New York as well as the Oakland Art Museum, Seattle Art Museum and other regional venues.
