(1898–1972). British physician, born in London. Penrose's father was a portrait painter and both his parents were members of the Society of Friends. After serving in the Friends' Ambulance Train of the British Red Cross during the First World War, he went in 1919 to St John's College, Cambridge, where he wanted to study mathematical logic with Bertrand Russell. He obtained his degree in 1921, and then studied with F. C. Bartlett and at the University of Vienna, where he did work on memory andperception in E. Buhler's laboratory and met Sigmund Freud. At this time, Penrose was very interested in the problems of abnormal psychology and mental disorder and realized that he would be advised to qualify in medicine in order to pursue this interest. He therefore went to Cambridge in 1925 and subsequently to St Thomas' Hospital in London. He presented his MD thesis on the subject of schizophrenia in 1930 and the following year applied for, and ultimately obtained, an appointment as research medical officer at the Royal Eastern Counties Institution at Colchester.
