of residence, as well as the completion of the Western Bank quadrangle and the extension of the Students' Union.
The university then grew slowly until the 1950s and 1960s when it began to expand rapidly. Many new buildings (including the Main Library and the Arts Tower) were built and older houses were brought into academic use. Student numbers increased to their present levels of just under 26,000. At the same time in the 1950s, the university was expanding at other sites, including the St Georges area. From the 1960s, many more buildings have been constructed or extended, including the Union of Students and St George's Library.

The 1980s saw the opening of many new buildings and centres, such as the multi-purpose Octagon Centre and the Sir Henry Stephenson Building. The university's teaching hospital, Northern General Hospital, was also extended. In 1987 the university began to collaborate with its once would-be partners of the Victoria University by co-founding the Northern Consortium; a coalition for the education and recruitment of international students. The university continued to expand in the 1990s. New premises were opened for School of the Clinical Dentistry, the Division of Education, and the Management School.

At Sheffield Krebs and his postgraduate student discovered the citric acid cycle (also known as the Krebs cycle) in 1937, which earned him a Nobel Prize for Medicine and Physiology for 1953. In 1938, the university opened the Department of Biochemistry (renamed since the 1990s as the Department of …
