author
1874–1949
A practical early-20th-century engineering writer, he is best known for explaining how vacuum cleaning systems worked and why they mattered in modern buildings. His surviving work turns a familiar household idea into a detailed look at hygiene, machinery, and design.

by M. S. (Maxwell Stephens) Cooley
Published in 1913, Vacuum Cleaning Systems: A Treatise on the Principles and Practice of Mechanical Cleaning is the work most clearly connected with M. S. Cooley, identified in library and public-domain records as Maxwell Stephens Cooley, born in 1874. The book was issued by the Heating and Ventilating Magazine Company and reflects a strong technical interest in building systems and mechanical cleaning.
Cooley wrote in a direct, practical way, focusing on principles, equipment, testing, and real-world application rather than literary flourish. That makes his work especially interesting today: it captures a moment when vacuum cleaning was emerging as an important part of healthier, more efficiently managed indoor spaces.
Reliable biographical details about his personal life are hard to confirm from the sources available here, so a full life story remains unclear. What does stand out is his contribution as a specialized technical author whose work preserves the language and concerns of early modern engineering.
