M. S. (Maxwell Stephens) Cooley

Born in 1874, M. S. Cooley — Maxwell Stephens Cooley — is known for Vacuum Cleaning Systems: A Treatise on the Principles and Practice of Mechanical Cleaning, published in 1913. The book was issued by the Heating and Ventilating Magazine Company in New York and later preserved by sources such as Project Gutenberg and the Internet Archive.

Cooley wrote at a time when engineers were rethinking how buildings should handle dust, sanitation, and maintenance. His book explains the principles, equipment, testing, and practical use of vacuum cleaning systems, showing how closely early mechanical engineering could connect with everyday life.

Little biographical information about him was readily confirmed in the sources I found beyond his full name and life dates, 1874–1949. Even so, his surviving work gives a strong sense of a careful technical author interested in making new building technology understandable and useful.
