1874–1939
A leading early osteopath and medical writer, this author helped shape how osteopathic medicine was taught in the early 1900s. His best-known books, including Clinical Osteopathy and The Practice of Osteopathy, were written for students and practicing physicians alike.

by Carl Philip McConnell, Charles Clayton Teall
Born in Wisconsin in 1874, Carl Philip McConnell became an important figure in the early development of osteopathic medicine. Sources connected with his books describe him as a D.O. and M.D., a professor of theory, practice, and diagnosis at the American School of Osteopathy in Kirksville, Missouri, and a member of the examining and operating staff of the A. T. Still Infirmary.
McConnell is best remembered today for substantial instructional works such as Clinical Osteopathy and The Practice of Osteopathy (written with Charles Clayton Teall). These books were aimed at both students and practitioners, and they reflect his role in turning osteopathy into a more systematic field of study with detailed guidance on diagnosis and treatment.
He died in 1939 at age 64. While biographical details about his personal life are limited in the sources I could confirm, his medical writing remains part of the historical record of osteopathic education and continues to be preserved by libraries, archives, and public-domain collections.
