Lionel Sharples Penrose, FRS (11 June 1898 – 12 May 1972) was an English psychiatrist, medical geneticist, paediatrician, mathematician and chess theorist, who carried out pioneering work on the genetics of intellectual disability. Penrose was initially the Galton professor of eugenics (1945–1963) at University College London, before having his title changed to professor of human genetics (1963–1965) at his request. He was later emeritus professor.
