William Hultz Walker

William Hultz Walker (April 7, 1869 – July 9, 1934) was born in Pittsburgh, Pa., and graduated in 1890 at Penn State College and took his Ph.D. at Göttingen (1892). In 1894 he accepted the chair of industrial chemistry at the Massachusetts Institute of Technology, where from 1908 he was also director of the research laboratory of applied chemistry. Walker was vice president of the International Congress of Applied Chemistry in 1893 and president of the American Electrochemical Society in 1910. The New York Section of the American Chemical Society conferred on him its Nichols medal in 1908.

William H. Walker, as he is commonly referenced, was one of the pioneers of chemical engineering practice and principles in the United States. He was the first graduate in chemistry at Penn State in 1890. He earned an M. S. in chemistry from Penn State, and a Ph. D. in organic chemistry from Göttingen University, before returning to Penn State, where he served as an instructor in chemistry in 1892 - 1894. He moved to Massachusetts Institute of Technology (MIT) in 1894, and in 1917 founded the School of Chemical Engineering Practice.

Although he was trained as a chemist, and worked as a chemistry educator, Dr. Walker was extremely influential in developing modern chemical engineering discipline. He is rightfully considered one of the founders of that discipline.

Dr. Walker and Arthur Dehon Little formed Little and Walker, a partnership, in 1900, where Walker worked until 1905. He then returned to full-time academic work as an associate professor at MIT, in charge of the newly opened Research Laboratory of Applied Chemistry. Little remained in business, which he incorporated as the Arthur D. Little, Inc. in 1909. Little and Walker maintained a professional relationship after dissolving the partnership. Little was active as member and chairman of the MIT Corporation Visiting Committees for Chemistry and Chemical Engineering. Little propounded the concept of "unit operations" to explain industrial chemistry processes in 1916.
