John (Inspector of Naval Hospitals) Wilson

He is identified in library and public-domain records as John Wilson, Inspector of Naval Hospitals, a naval medical officer who wrote about the treatment of cholera at the Royal Hospital, Haslar. His best-known surviving work, Treatment of Cholera in the Royal Hospital, Haslar during the months of July and August, 1849, draws on firsthand observation during the outbreak.

The book is valuable not just as a medical report, but as a window into mid-19th-century medicine. Wilson discusses symptoms, treatment methods, patient outcomes, and the wider debate over the nature and origin of cholera, showing how doctors of the period balanced practical care with uncertain scientific knowledge.

Very little biographical detail beyond his professional role could be confirmed from the sources found in this search, so the picture that remains is mostly the one preserved in his writing: an experienced hospital inspector documenting epidemic disease from within the naval medical system.
