Louis M. (Louis Marshall) Warfield

Louis M. Warfield, listed in archival records as Louis Marshall Warfield and born in 1876, was an American physician and medical author. A Washington University in St. Louis archival authority record confirms his name and gives his dates as 1876-?, suggesting that basic details of his later life are not firmly documented in the sources readily available online.

He is known for Arteriosclerosis: Etiology, Pathology, Diagnosis, Prognosis, Prophylaxis, and Treatment, published in 1908. Catalog and book records identify him as the author, and a Google Books record describes him at that time as assistant superintendent and resident physician at Milwaukee County Hospital, as well as assistant professor of medicine at the Wisconsin College of Physicians and Surgeons.

That combination of roles helps explain the tone of his writing: it comes from someone working at the intersection of bedside medicine, hospital administration, and medical education. While a fuller personal biography is hard to confirm from the available sources, his published work clearly places him among the physicians who helped shape early modern discussion of cardiovascular disease.
