William Redfern (1775 – 17 July 1833) was the Surgeon’s First Mate aboard HMS Standard during the May 1797 Nore mutiny, and at a court martial in August 1797 he was sentenced to death for his involvement. His sentence was later commuted and in 1801 he was transported to New South Wales and assigned as an assistant to the Norfolk Island hospital. In this post he demonstrated the medical skills that enabled him to become one of the colony’s most revered physicians and a pioneer in public health. Redfern advocated major reforms to sanitary conditions aboard convict ships and this significantly reduced the morbidity rates of convicts arriving in NSW. Later in life he became a highly successful farmer, bank director and an emancipist rights activist.
