When Petroleum Refining Was the Frontier

Notwithstanding such intradisciplinary conflicts, the transformation of chemical engineering that Walker led was remarkably successful, and he is widely regarded as the father of the discipline. Testimony to the success were the impacts of graduates, ideas, approaches, and research results on the chemical and petroleum industries of the United States. That country had come out of World War I the world s most powerful economy [32]. 

The little book, Differential Equations in Applied Chemistry (Fig. 6), has been unsung for years, though all through an era when few engineers truly understood calculus it showed off powerful mathematical tools, among them (in the 1936 second edition) numerical solution methods. It connected with chemist J. W. Mellor s 1902 Higher Mathematics for Students of Chemistry
