He left Harvard after quarreling with his mentor T. W. Richards, after which he became Superintendent of the Bureau of Weights and Measures in the Philippines.  He published the seminal books Valence and the Structure of Atoms and Molecules and Thermodynamics and the Free Energy of Chemical Substances shortly after serving as chief of his nation's Chemical Warfare Service in World War I.  His later researches elucidated the role of the triplet state in phosphorescence, and this man's work in photochemistry led him to coin the term "photon."  Legend has it that this educator inaugurated the tradition of difficult problem sets in chemistry courses while dean of the College of Chemistry at Berkeley.  FTP, name this American chemist, the first man to isolate a pure sample of heavy water and namesake of an electron mediated acid-base definition and certain dot structures.
