Janet Harley (NIAID), Rowe used this abacus for many years “in making rapid calculations for data analysis—before and even after hand calculators were readily available.” His use of this calculation aid is of interest because many of Rowe’s research contributions had important and fairly sophisticated mathematical aspects. Berger, who owned this rule, began his career at the NIH in 1962 in the Laboratory of cal Development, NBI. patents: the first in 1988 for the computer-controlled all-tantalum stopped-flow micro calorimeter; and the second in 1992 for the hh-resolution dital thermometer. This slide rule is one of the commonly used 6-inch slide rules, equivalent to a 14-inch straht slide rule in calculation power. Dempster of Berkeley, California, filed the first patent filed for a circular slide rule on April 30, 1928; the patent was issued on March 15, 1932.
