A Champion for Chemistry: Elements of Jim Morgan's Intellectual Legacy.

James (Jim) Morgan was a leading figure in the field of environmental science and engineering. He championed the application of chemistry in the study of the environment and the design and optimization of environmental treatment processes. Jim influenced the field through his classic text Aquatic Chemistry, coauthored with Werner Stumm, his role as founding editor of Environmental Science & Technology, his seminal contribution to computational methods for the calculation of chemical equilibria, and most especially, his mentorship of his extended academic family. Jim transmitted his enthusiasm for research, particularly on the chemistry of manganese and iron, so successfully to his doctoral students and postdoctoral advisees that many of them carried these topics forward in their own careers.
