1849–1918
A New Hampshire physician and public health reformer, he wrote practical medical works at a time when sanitation and disease prevention were becoming urgent public concerns. His books reflect a hands-on interest in clean water, disinfection, and the systems communities needed to stay healthy.

by Irving A. (Irving Allison) Watson
Born in Salisbury, New Hampshire, in 1849, Irving Allison Watson studied medicine at Dartmouth and the University of Vermont, graduating in 1871. He practiced medicine in northern New Hampshire before moving to Concord, where his career became closely tied to public health work.
Watson is best remembered for his long service as secretary and executive officer of the New Hampshire State Board of Health, a role he held from the board’s founding in 1881 until his death in 1918. He was also active beyond his state, serving for many years as secretary of the American Public Health Association.
As an author and editor, he wrote on sanitation, disinfection, and water safety, and he compiled Physicians and Surgeons of America. His writing has a practical, civic-minded feel: it was meant not just for specialists, but for improving everyday health and preventing disease.
