Green College was a graduate college of the University of Oxford in England. It was centred around an architecturally appealing 18th century building: the Radcliffe Observatory, which is modelled after the ancient "Tower of the Winds" in Athens. Established in 1979, the college was one of the youngest of the university, and was named after its main benefactors: Dr Cecil H. Green and his wife Dr Ida Green. Dr Green was a founder of Texas Instruments. Green College, Oxford was one of two colleges established due to his generosity, the other being Green College, University of British Columbia. Green College was dedicated to human welfare in contemporary society. This was interpreted as an academic focus on medicine. Related disciplines, such as education, the environment and social sciences, however, were also covered. 30% of the students studied in the field of medicine. About 20% were engaged in medical research on a post-graduate level. Social Work, environmental change and educational studies were other strongholds of the college.
