content: These seventeen black slides are glass with geometric curves shown on them in white. Black tape covers the rim of the glass. All but three of the slides have a typed paper tag in one corner that reads: Saul Pollock, Pollock, a mathematician who obtained his PhD. from Berkeley in 1931, made a variety of ruled surfaces, including some exhibited at the World's Fair held in Chicago in 1933. Apparently Pollock also designed lantern slides that showed mathematical curves and projected them onto his ruled surfaces, generating new space curves. It is possible that these slides were used for that purpose.
