content: These three photographs relate to the hydraulic slide rule developed for calculations relating to pumps and pipelines at the Georgia Iron Works (2009.0100.01). A snapshot from 1961 shows the slide rule as it was first designed. A second image shows the designer, Danforth W. Hagler, in an office in the 1960s. The third, which is somewhat later, shows Hagler at the console of an IBM 1130 computer. In that photograph, an oversized version of the slide rule he invented is mounted on the wall.
