to use the title of "Vice-Chancellor and Warden".
After World War II, the Durham division expanded rapidly. St Aidan's Society (St Aidan's College from 1961) was founded in 1947 to cater for non-resident women and the decision was made to expand further on Elvet Hill (where the science site had been established in the 1920s), relocating St Mary's College, building new men's colleges, vastly expanding the existing pure science provision in Durham, and adding applied science (1960) and engineering (1965).
In 1947, the foundation stones for the new St Mary's College building on Elvet Hill were laid by Princess Elizabeth (later Queen Elizabeth II). The new building opened in 1952. In the same year, tensions surfaced again over the Durham–Newcastle divide, with the university court putting forward a proposal to change the name of the university to the "University of Durham and Newcastle". This motion was defeated in convocation (the assembly of members of the university) by 135 votes to 129. Eleven years later, with the Universities of Durham and Newcastle upon Tyne Act 1963, King's College became the University of Newcastle upon Tyne, leaving Durham University based solely in its home city.

By the time of the separation from Newcastle the Elvet Hill site was well established; with the first of the new colleges being founded in 1959, Grey College, named after the second Earl Grey who was the prime minister when the university was founded. Expansion up Elvet Hill continued, with Van Mildert College, Trevelyan College (1966), and Collingwood College (1972) all being added to the university, along with the relocation of the botanic garden (1970) and the business school (1977).
These were not the only developments in the university, however. The Graduate Society, catering for postgraduate students, was founded in 1965 (renamed Ustinov College in 2003) and the Roman Catholic seminary of Ushaw College, which had been in Durham since 1808, was licensed as a hall of residence in 1968 …
