- In the mid-twentieth century, engineers designing slide rules often carried out extensive calculations by hand. The documentation for the Georgia Iron Works hydraulic slide rule (2009.0100.01) includes numerous pages of such calculations, as well as four blueprints showing the design of the rule. Correspondence between Danforth W. Hagler, who designed the slide rule, and officials of Pickett & Eckel Company, the manufacturer, is also included. The letters and drawings are dated 1961.
