author
b. 1851
Remembered for practical health and household books aimed at everyday readers, this late-19th-century physician-author wrote in a direct, advice-giving style that reached a wide popular audience. His best-known work, co-written with J. L. Nichols, brought medical, moral, and domestic guidance together in one volume.

Benjamin Grant Jefferis (1851–1929) was a physician and author whose surviving bibliographic records connect him with Chicago and with medical training at the Kentucky School of Medicine, Louisville, part of Transylvania University's medical department. Reference listings consistently identify him as both a doctor and a writer, and they place his life span from 1851 to 1929.
He is best known for works such as Searchlights on Health and Safe Counsel, written with J. L. Nichols. Those books mixed health advice, household guidance, and discussions of courtship, marriage, and sexuality for a broad general readership, which helps explain why his name still appears in library, public-domain, and medical-history collections.
Because easily available biographical details are limited, a full personal portrait is harder to confirm than his publications. Still, the record that does survive shows a writer-physician who focused on practical instruction and produced books that circulated widely enough to remain preserved in major archives and reference catalogs.
