C. O. (Charles Oren) Benson

C. O. Benson — identified in library and public-domain records as Charles Oren Benson (1906–1974) — wrote short, practical guides on exercise and physical well-being. His books include Constipation and Its Correction by Exercise and Correction of Underweight and Overweight by Exercise, both of which present movement and routine as tools for better health.

One edition of Constipation and Its Correction by Exercise describes him as an instructor of physical education at Washington University in St. Louis, which fits the hands-on, instructional tone of his work. His books were issued by Haldeman-Julius Publications, a publisher known for inexpensive, accessible booklets meant for general readers rather than specialists.

Very little biographical information about Benson appears to be widely available online today. What does come through clearly is his practical approach: he wrote in a plain, encouraging style and focused on simple habits readers could use to improve everyday health.
