author
b. 1882
A prolific early 20th-century veterinary writer, he focused on practical treatments and field medicine for horses, cattle, and other farm animals. His books are straightforward, hands-on guides from an era when veterinary care was closely tied to everyday agricultural life.

by Mart R. (Martin Robert) Steffen
Born in 1882, Martin Robert Steffen wrote a number of veterinary manuals and reference works in the 1910s and later. Surviving catalog records and digitized editions identify him as the author of books including Special Cattle Therapy (1915), The Itinerant Horse Physician (1916), Veterinary Clinical Notes (1917), and A Treatise on Regional Iodine Therapy for the Veterinary Clinician (1919).
His writing centers on practical veterinary diagnosis and treatment, especially for livestock and horses. The emphasis in these works is clinical and usable rather than literary, which makes them a window into how animal medicine was taught and practiced in the early twentieth century.
Some editions connect him with Milwaukee, Wisconsin, and several library records continue listing later farm-animal titles under his name. Beyond those publication details, reliable biographical information appears to be scarce, so much of what remains visible today is preserved through library catalogs and public-domain scans of his veterinary texts.
