1880–1940
Best known for early 20th-century chiropractic textbooks, this American writer focused on practical subjects like orthopedy, hygiene, and pediatrics. His surviving books give a clear glimpse of how chiropractic education was being taught in the 1920s.

by J. H. (John Henry) Craven
John Henry Craven (1880–1940) was an American chiropractic author and publisher whose work centered on professional training. Records for his books show that he wrote A Text-Book on Chiropractic Orthopedy in the early 1920s and later published A Text-Book on Hygiene and Pediatrics from a Chiropractic Standpoint in 1924.
His writing appears to have been aimed at students and practitioners rather than general readers. The subjects he chose—posture and structural problems, hygiene, and children's health—suggest a strong interest in building a practical textbook literature for chiropractic study.
Little biographical information was confirmed in the sources I found beyond his dates and published works. Even so, his books remain useful as historical documents, reflecting the language, methods, and medical ideas circulating in chiropractic education during his era.
