Robert Knox, Scottish surgeon and zoologist (born 1791)

Robert Knox was a Scottish anatomist and ethnologist best known for his involvement in the Burke and Hare murders. Born in Edinburgh, Scotland, Knox eventually partnered with anatomist and former teacher John Barclay and became a lecturer on anatomy in the city, where he introduced the theory of transcendental anatomy. However, Knox's incautious methods of obtaining cadavers for dissection before the passage of the Anatomy Act 1832 and disagreements with professional colleagues ruined his reputation in Scotland. Following these developments, he moved to London, though this did not revive his career.
