Charles Poindexter Wertenbaker

Charles Poindexter Wertenbaker was born in Charlottesville, Virginia, on April 1, 1860, and died there on July 12, 1916. Sources available here identify him as a physician, surgeon, and officer in the United States Public Health and Marine-Hospital Service, later also noted as a colonel in the U.S. Army.

He is best known as the author of A Working Plan for Colored Antituberculosis Leagues (1909). In that booklet, published from his work in public health, he set out a practical plan for organizing state and church-based leagues to combat tuberculosis through education, reporting, sanitation, and local support.

Because biographical information on him is limited in the sources I could confirm, this portrait stays focused on the essentials: Wertenbaker was a medical officer whose writing reflects the era's public health campaigns and the use of organized local action against infectious disease.
