1709–1779
A Scottish doctor who turned medicine into poetry, he is best remembered for The Art of Preserving Health, a lively 18th-century poem on well-being. His work mixes wit, learning, and the everyday concerns of health in a way that still feels surprisingly modern.

Born in Scotland around 1709, John Armstrong studied medicine at the University of Edinburgh and later built his career in London. He was both a practicing physician and a man of letters, moving in literary circles while writing poetry, satire, and essays.
His best-known work is The Art of Preserving Health (1744), a didactic poem that made an unusual subject—healthy living—engaging for readers of his time. He also wrote other poems and prose pieces, bringing together medical knowledge, observation, and a sharp, sometimes playful style.
Armstrong died in 1779. He is remembered less as a single-book curiosity than as a distinctive 18th-century voice who joined science and literature in an especially readable way.
