Alan Julian Macbeth Tudor-Hart (9 March 1927 – 1 July 2018), commonly known as Julian Tudor Hart, was a general practitioner (GP) who worked in Wales for 30 years, known for theorising the Inverse care law. He produced medical research and wrote many books and medical articles. Early life Hart was born in London on 9 March 1927, the son of Alexander Tudor-Hart and Alison Macbeth. He studied medicine at Cambridge University and in London, graduating in 1952. He is a descendant of American businessman Frederic Tudor and Ephraim Hart, a Bavarian Jew who became a prominent merchant in New York, and was reportedly partners with John Jacob Astor. The name was originally Hirz. His paternal grandfather, the Canadian artist Percyval Hart, married his Polish-French cousin Éléonora Délia Julie Aimée Hart Kleczkowska, and later changed the family surname to Tudor-Hart. Kleczkowska was the daughter of diplomat Michel Alexandre Cholewa, comte Kleczkowski (Michał Kleczkowski; 1818–1886) and granddaughter of Julie Sobieska, a direct descendant of John III Sobieski, king of Poland in the 17th century. He was a member of the Sigerist Society from 1947 to 1955. Hart joined the Communist Party of Great Britain, following his father Alex, and stood unsuccessfully as the CPGB candidate for Aberavon at the 1964, 1966 and 1970 general elections. Career In 1961, he moved to Glyncorrwg in Wales. There, he worked for 30 years as a general practitioner. One of his partners was Brian Gibbons, later minister for health in Wales. Hart became involved in epidemiological research, with Richard Doll and Archie Cochrane. He was a passionate advocate of the National Health Service and of socialism. He was President of the Socialist Health Association. He was a Fellow of the Royal College of General Practitioners (RCGP) and the Royal College of Physicians (RCP). In 2006, he was awarded the inaugural Discovery Prize by the RCGP as "a general practitioner who has captured the imagination of generations of GPs with his groundbreaking research". His practice in Glyncorrwg, Wales, was the first in the UK to be recognised as a research practice, piloting many Medical Research Council studies. He was also the first doctor to routinely measure every patient's blood pressure and as a result was able to reduce premature mortality in high risk patients at his practice by 30%. Graham Watt, professor of general practice at the University of Glasgow, nominated Tudor Hart for the award.
