author
b. 1882
An early 20th-century veterinary writer, he focused on practical treatment methods for horses and cattle at a time when animal medicine was still taking shape. His surviving books have a straightforward, working-doctor feel that makes them a vivid window into historical veterinary practice.

by Mart R. (Martin Robert) Steffen
Born in 1882, Mart R. Steffen — also published as Martin Robert Steffen — wrote veterinary manuals and clinical guides in the 1910s. Library and archive records connect him with works such as The Itinerant Horse Physician (1916), Veterinary Clinical Notes (1917), Special Veterinary Therapy, and A Treatise on Regional Iodine Therapy for the Veterinary Clinician (1919).
His books center on hands-on diagnosis and treatment, especially for horses and cattle. The emphasis is practical rather than academic, suggesting he wrote for working veterinarians who needed concise guidance they could use in the field.
Very little biographical detail beyond his birth year is easy to confirm from reliable public sources. Even so, his books remain useful as historical documents from an era when veterinary medicine was becoming more systematic and specialized.
