provost in 1912 as the chief academic officer, who "would be associated with the President and the Secretary of the university in the consideration and oversight of matters of general university concern and in the preparation of general university business for consideration either by the Trustees, the University Council, or the appropriate Faculty." It fell vacant again between 1926 and 1937, but on its restoration was seen as the second officer in the administration, behind only the president. Other American universities and colleges created provosts as heads of academic affairs during and after World War II, when dramatic increases in undergraduate enrollments (due to the G.I. Bill) and the increased complexity of higher education administration led many chief executive officers to adopt a more corporate governing structure. By the 1960s, many private research universities had provosts installed as their chief academic officers, including Brown (1949), Chicago (1963), Cornell (1931), Dartmouth (1955; in abeyance 1972–79), Duke (1960), Johns Hopkins (1924), MIT (1949), Princeton (1966), Rice (1954), Stanford (1952), Tufts (1951), Wake Forest (1967) and Yale (1919). Harvard was a notable holdout: a provost had been appointed in 1933, but only with authority over the Faculty of Arts and Sciences, and the position had been eliminated in 1953. It was not until 1995 that Harvard appointed a university-wide provost. The use of provost as the title of the chief academic officer of a university (as opposed to its historic use for the head of a college) is relatively recent in the UK. One of the earliest was Imperial College London, where the first provost was appointed in 2012, splitting off the chief academic officer role previously carried out by the rector (chief executive) of the university after a governance review. The vice-chancellor (chief executive) of Durham University praised this arrangement in 2014, following a governance review that recommended it at that university, saying "The Vice-Chancellor’s role in an international university like this now is something that cannot be done by one person with all the external and internal stuff you have to do. In America it’s been the case all the time that they’ve had a president and a provost, with the president being the equivalent of Vice-Chancellor. This more or less splits the external and internal duties. Personally I believe that we should move to this model – Imperial [College] has done it, I believe the LSE [London School of Economics]
