John King [Nicholas Johann Koenig] (1766–1846): Bristol-based surgeon, painter and linguist, originally from Berne, Switzerland. He came to England in the 1790s and studied medicine under John Abernethy (1764–1831; DNB) at St Bartholomew’s Hospital, before settling at Clifton in Bristol. He married Emmeline Edgeworth, a sister of the novelist Maria (1768–1849; DNB). Southey came to know King well when he succeeded Davy in his role at the Pneumatic Institution in 1801. Southey saw much less of King after he moved to Keswick in 1803, but he continued to speak warmly of his personal qualities and medical skill.
