Robert Knox, Scottish surgeon and zoologist (b. 1791)
Robert Knox (4 September 1791 – 20 December 1862) 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 career in Scotland. Following these developments, he moved to London, though this did not revive his career.

Knox's views on humanity gradually shifted over the course of his lifetime, as his initially positive views (influenced by the ideals of Étienne Geoffroy Saint-Hilaire) gave way to a more pessimistic view. Knox also devoted the latter part of his career to studying and theorising on evolution and ethnology; during this period, he also wrote numerous works advocating scientific racism. His work on the latter further harmed his legacy and overshadowed his contributions to evolutionary theory, which he used to account for racial differences.
