He studied medicine at Queens' College, Cambridge, and then at St George's Hospital Medical School in London, graduating in 1952.

[3][4] 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.

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.

[13] In 2006, he was awarded the inaugural Discovery Prize[14] by the RCGP as "a general practitioner who has captured the imagination of generations of GPs with his groundbreaking research".

Graham Watt, professor of general practice at the University of Glasgow, nominated Tudor Hart for the award.

His last book, The Political Economy of Health Care: A Clinical Perspective explores how the NHS might be reconstituted as a humane service for all (rather than a profitable one for the few) and a civilising influence on society as a whole.
