Since the admission of women in 1974, when Jesus was among the first five men's colleges to become co-educational, the College has been among the most academically successful in the University.Nearly one third ofthe present complement of tutorial fellows and lecturers, professorial, senior and junior research fellows and Hugh Price fellows are women. Women now comprise about one half of the undergraduate body. In 1998, Jesus College gained the highest number of first-class degrees of any college in Oxford. The College has also achieved recent prominence with the appointment of two successive Principals as Vice-Chancellors of the University during periods of critical change: the economic historian Sir John Habakkuk (Principal 1967-1984) in 1973-1977, and the lawyer Sir Peter North (Principal 1984-2005) in 1993-1997. Between 1997 and 2015, the Principal was the zoologist Lord Krebs, Kt, FRS, FMedSci. The current Principal is Sir Nigel Shadbolt, FREng.
