Watercolor U.S.A. Honor Society
The first move of The Watercolor USA Honor Society was to hold a symposium in Spring Green, Wisconsin, to find out who the members were, what WHS was about, and what the organization might be capable of. The first meeting was held in the Aldebaran barn adjacent to Frank Lloyd Wright’s hillside school at Taliesin East. The trailblazers present were Bill Armstrong and Bill Landwehr as co-chairmen, Lee Weiss, Bob Johnson, Bill Senter, Francis Meisch, Judy Gard, Edward Betts, Jim Foosey, Fred Messersmith, Jerry Baum, E.J. Velardi, Carl Sublett, Rosalee Price, Merry Berry, Judi Betts, Rich Clubb, Edward Herbleck, and Doris White. The first Directors elected from the fledgling Watercolor USA Honor Society were Bill Armstrong, the first President; Lee Weiss, Vice-President; Bob Johnson, Secretary; and Bill Senter, Treasurer.
