About 45 members of NASS attended the third annual conference in the windy city of Chicago. The Adler Planetarium hosted the conference and provided a tour of their fine collection of astrolabes and sundials. Of particular interest was the special sundial exhibit prepared by Sara Schechner Genuth for the conferees in the History of Astronomy Department. NASS sessions started with John Shephed describing his design of a vertical declining sundial 56 feet wide. Warren Thom talked about sundial computer aided design using several popular programs. Fred Sawyer took the mathematical side and presented a new sundial, described as “Ptolemaic Coordinate Sundials” which he invented in response to a British Sundial Society challenge.
