WALTER L. Du MOULIN
Arizona, The Youngest State, 1913, pg 606

Walter L. Du Moulin, superintendent of the Morenci Water 
Company, has had a varied experience in responsible positions 
of civil engineering since the beginning of his active career 
and although still a young man, possesses in his ability and 
well developed intellectual powers the elements of 
distinguished attainment along professional lines. He was 
born in Joliet, Illinois in 1882 and is a son of Ferdinand 
and Emma Du Moulin, residing in the latter city, who are the 
parents of two children, Walter L. of this review and Alice, 
who resides at home.

Walter L. Du Moulin was reared in Illinois and acquired his 
preliminary education in the public schools of that state. He 
later completed his high school course in Pontiac, Illinois, 
followed this by a full business course and supplemented that 
by a course in electrical and mechanical engineering in the 
University of Illinois at Urbana, leading to a degree of M.E.  
After a general business experience along mercantile lines, Mr. 
DuMoulin came to Arizona in 1904 and settled in Globe, where he 
acted as draughtsman for the Old Dominion Copper Mining and 
Smelting Company and as first assistant to C.F. Moore, 
mechanical engineer of that concern.  After one year, he 
went to Troy, New York in order to still further carry 
forward his technical studies at the Rennsselaer Polytechnic 
Institute, from which he was graduated in 1908 with the 
degree of C.E. being honored with election to membership in 
both the honorary engineering fraternity Tau Beta Pi and the 
honorary scientific fraternity Sigma Xi.  Thus splendidly 
equipped he went to Cananea, Sonora, Mexico and there became 
identified with the Cananea Consolidated Copper Company with 
which he continued until January 1, 1910 when he came to 
Morenci as superintendent of the Morenci Water Company.  He 
has accomplished a great deal of construction work since 
taking charge, increasing the capacity of the plant, 
systematizing methods of operation and doing all in his 
power to promote efficiency of service.  This is the largest 
privately owned water company in the state.  Mr. Du Moulin 
occupies a prominent place in business circles of Morenci, 
which he holds by reason of his comprehensive knowledge of 
the details of his profession.
