Hagler, who's family ran Georgia Iron Works, Grovetown, Ga., conceived and designed the GIW Hydraulic Slide Rule. His brother Tom, wrote the manual. Before its invention, each engineer in the engineering department had a large, thick notebook with about 100 pages of graphs. The slide rule incorporated many hydraulic pump and pipeline formulas. One side of the slide rule contained engineering formulas involved with performance of a pump while the other side contained everything necessary for pipeline and production calculations.

Eaton, PhD., Boulder, Colorado Robert C Eaton (1946 - present) used this slide rule starting in his student years in 1963, and throughout his career as a scientist in biophysics. Trained at several different universities in the US & Europe. Worked as research scientist at Scripps Institution of Oceanography, and later became a Professor and Department Chair at the Univ. of Colorado at Boulder. Professor Eaton studied the neural control of movement using high-speed film & digital cameras, electrical recordings from brain cells, and computer models of neural network processes. After computers became commonplace, he often surprised students and associates by pulling out this slide rule to do a quick analogue calculation. Robert retired in 2003 and lives in Boulder, Colorado with his wife Katie.

The contestants had to complete a series of calculations in 30 minutes. As the competition was timed there was a premium on speed but the marking system also required high accuracy. If the answer was accurate to three place of decimals, three points were awarded but if the answer was off by more than 2 places in the third significant figure no marks were awarded. Whilst other rules were allowed, and were used, the Pickett "Texas speed rule" was most popular. Ref: Ron Manley

Pickett Teaching (Classroom size) Slide Rules Pickett manufactured large slide rules for mounting in class rooms. They came in 4 foot and 7 foot versions. The stock and slide are of plywood (tounge and grooved), the end brackets are sheet aluminum. The cursor consisted of pine with aluminum paint, with a clear plastic lens. Both sizes came with metal eye loops for hanging from a wall or ceiling. Go to Pickett Demonstration and Teaching Slide Rules
