The Early Development of Electronic pH Meters
Hines, Wallis G.; de Levie, Robert
Journal of Chemical Education, v87 n11 p1143-1153 Nov 2010
A 19-year-old undergraduate at the University of Chicago, Kenneth Goode, in 1921 came up with the idea of an electronic pH meter, worked out some of its initial problems, and set in motion an international scientific effort that culminated in the current, wide availability of electronic pH meters. Except for the replacement of vacuum tubes by solid-state electronics, modern pH meters closely follow his original designs. (Contains 10 figures.)
