Merle Randall (January 29, 1888 – March 17, 1950)[1] was an American physical chemist famous for his work with Gilbert N. Lewis, over a period of 25 years, in measuring reaction heat of chemical compounds and determining their corresponding free energy. Together, their 1923 textbook "Thermodynamics and the Free Energy of Chemical Substances" became a classic work in the field of chemical thermodynamics.
In 1932, Merle Randall authored two scientific papers with Mikkel Frandsen: "The Standard Electrode Potential of Iron and the Activity Coefficient of Ferrous Chloride,"[2] and "Determination of the Free Energy of Ferrous Hydroxide from Measurements of Electromotive Force."[3]
