For several years I was an active member of the National Stereoscopic Association, serving as the Eastern Regional Director as well as the Curator of the Oliver Wendell Holmes Steroscopic Library. I gave an 3-D illustrated lecture on the life of Sir David Brewster at the national convention in St. Louis in 1980 and wrote two articles for Stereo World, the organization's bi-monthly magazine. Those articles are included here. The paper will appear here soon.
