History of Somerville College, Oxford

Founding

In June 1878, the Association for the Higher Education of Women was formed, aiming for the eventual creation of a college for women in Oxford. Some of the more prominent members of the association were George Granville Bradley, Master of University College, T. H. Green, a prominent liberal philosopher and Fellow of Balliol College, and Edward Stuart Talbot, Warden of Keble College. Talbot insisted on a specifically Anglican institution, which was unacceptable to most of the other members. The two parties eventually split, and Talbot's group (the "Christ Church camp") founded Lady Margaret Hall, which opened its doors for students in 1879, the same year as Somerville did.

Thus, in 1879, a second committee was formed to create a college "in which no distinction will be made between students on the ground of their belonging to different religious denominations." This committee was called the "Balliol camp" and had close ties to the Liberal Party. This second committee included John Percival, George William Kitchin, A. H. D. Acland, Thomas Hill Green, Mary Ward, William Sidgwick, Henry Nettleship, Walter Pater and A. G. Vernon Harcourt.

This new effort resulted in the founding of Somerville Hall, named for the then recently deceased Scottish mathematician and renowned scientific writer Mary Somerville. It was felt that the name would reflect the virtues of liberalism and academic success which the college wished to embody. She was admired by the founders of the college as a scholar, as well as for her religious and political views, including her conviction that women should have equality in terms of suffrage and access to education.

Madeleine Shaw Lefevre was chosen as the first Principal because, although not a well-known academic at the time, her background was felt to reflect the college's political stance. Because of its status as both women's college and non-denominational institution, Somerville was widely regarded within Oxford as "an eccentric and somewhat alarming institution."

Mary Somerville, 1780–1872, after whom the College is named

Women's college

When opened, Somerville Hall had twelve students, ranging in age between 17 and 36. The first 21 students from Somerville and Lady Margaret Hall attended lectures in rooms above an Oxford baker's shop on Little Clarendon Street. Just two of the original 12 students admitted in 1879 remained in Oxford for three years, the period for which male students had to remain to complete a bachelor's degree.

Increasingly, however, as the college admitted more students, it became more formalized. Somerville appointed its first in-house tutor in 1892 and, by the end of the 1890s, female students were permitted to attend lectures in almost all colleges. In 1891 it became the first women's hall to introduce entrance exams and in 1894 the first of the five women's halls of residence to adopt the title of 'college' (changing its name to Somerville College), the first of them to appoint its own teaching staff, and the first to build a library. In Oxford legend it soon became known as the 'bluestocking college', its excellent examination results refuting the widespread belief that women were incapable of high academic achievement.

In the 1910s, Somerville became known for its support for the women's suffrage campaign. In 1920, Oxford University allowed women to matriculate and therefore gain degrees. All female students had to be chaperoned when in the presence of male students from the college's inception. The practice was abolished in 1925, although male visitors to the college were still subject to a curfew. In 1925, during the principalship of Janet Vaughan, Somerville's college charter was granted.

World War One

During World War I the college was converted into a military hospital as Somerville Section of the 3rd Southern General Hospital, adjacent to the Radcliffe Infirmary. For the duration of the war, Somerville students relocated to Oriel College. Because many male students had left Oxford to enlist in the military, Somerville was able to rent St Mary Hall Quad which they bricked off from the rest of the college to segregate it from the Oriel's remaining male students. Many students and tutors were involved in work in World War I and some of them went to the Western Front in France.

Notable patients who stayed in Somerville include Robert Graves and Siegfried Sassoon. Graves and Sassoon were both to reminisce of their time at Somerville Hospital. How unlike you to crib my idea of going to the Ladies' College at Oxford, Sassoon wrote to Graves in 1917, and called it very much like Paradise. At Somerville College, Graves met his first love, a nurse and professional pianist called Marjorie. About his time at Somerville, he wrote: I enjoyed my stay at Somerville. The sun shone, and the discipline was easy. Officer Llewelyn Davies died at the college. Photographs of the college in this period can be found hanging in Hall, outside the pantry.

Once the war ended, the return to normality between Oriel College and Somerville College was delayed, sparking both frustration and an incident in spring 1919 known as the 'Oriel raid', in which male students made a hole in the wall dividing the sexes. In July 1919 the Principal (Emily Penrose) and Fellows returned to Somerville.

Alumna Vera Brittain wrote about the impact of the war in Oxford and paid tribute to the work of the Principal, Miss Penrose, in her memoir Testament of Youth.

Admission of men

Starting in the 1970s, the traditionally all-male colleges in Oxford began to admit female students. Since it was assumed that recruiting from a wider demographic would guarantee better students, there was pressure on single-sex colleges to change their policy to avoid falling down the rankings. All-female colleges, like Somerville, found it increasingly difficult to attract good applicants and fell to the bottom of the intercollegiate academic rankings during the period.

During the 1980s, there was much debate as to whether women's colleges should become mixed. Somerville remained a women's college until 1992, when its statutes were amended to permit male students and fellows; the first male fellows were appointed in 1993, and the first male students admitted in 1994. Somerville became the second-last college (after St Hilda's) to become coeducational. With an intake 50% male/female; a gender balance maintained to this day, though without formal quotas.

In the 1890s Somerville helped fashion the "New Woman"; a century later….the college has set itself the perhaps greater challenge of educating the "New Man."

Buildings of Somerville College, Oxford

Walton House

House from the Quad

The original building of Somerville Hall, Walton House (commonly called 'House') was built in 1826 and purchased from St John's College in 1880 amid fears that the men's colleges might, in the future, repossess the site for their own purposes. The house could only accommodate 7 of the 12 students who came up to Oxford in the first year. In 1881, Sir Thomas Graham Jackson was commissioned to build a new south wing which could accommodate eleven more students. In 1892, Walter Cave added a north wing and an extra storey. He also installed a gatehouse at the Woodstock Road entrance. In 1897/98, the 'Eleanor Smith cottages' were built, adjoining Walton House.

Today House is home to some students. It also contains Green Hall, where guests to College are often greeted and in which prospective students are registered and wait for interviews. Until 2014, it housed the college bar. Most of the administration of college and academic pigeon-hole messageboxes are located in House. A staircase from Green Hall leads up to Hall. Somerville's dining hall has a curved ceiling and wooden panelling and is one of very few in Oxford to contain portraits only of women.

Park

Main Quad (looking westwards), from left to right: Penrose, Wolfson, Park, Holtby

Originally known as West, due to its location within the college, the project to build a second self-contained hall was an attempt to imitate Newnham College, Cambridge. The building was designed by Harry Wilkinson Moore and built in two stages. The 1885-7 phase saw the construction of rooms for 18 students with their own dining-room, sitting rooms and Vice-Principal. This was a deliberate policy aimed at replicating the family environment that the women students had left. This arangement had the effect of turning House and West into rivals. The second building stage (1888-1895) created two sets of tutors' rooms, a further 19 rooms and the West Lodge (now Park Lodge). It was renamed Park in honour of Daphne Park, the Principal from 1980 to 1989.

There are over 60 student rooms and Fellows' rooms within the building. There is a music room and computer room. Park is a Grade II-listed building.

Library*

Main article: Somerville College Library

Somerville College Library

Designed by Basil Champneys in 1903 and opened by John Morley the following year, Somerville College Library was the first purpose-built library amongst the women's colleges of the university. Specially for this opening, Demeter was written by Robert Bridges and performed for the first time. As such it was designed to serve readers beyond the membership of the college and to contain 60,000 volumes despite the college only possessing 6000 in 1903. The Grade II-listed building now contains around 120,000 items and is the second largest college library in the university.

Amelia Edwards, John Stuart Mill, John Ruskin and Vera Brittain are notable benefactors to the library.

The John Stuart Mill room contains what was Mill's personal library in London at the time of his death, with significant annotations in many of the books.

The library dominates the north wing of the main quadrangle and is open 24 hours, with wifi access which is college-wide, a group study room, and many computers. It has with 100% the highest library satisfaction according to the annual student surveys.

Hall and Maitland

View of Hall and Maitland (right) from the quad

High Table in Hall

Until 1911, there was no hall large enough to seat the entire college. The buildings were designed by Edmund Fisher in Queen Anne style and Edwardian Baroque architecture. Maitland Hall and Maitland were opened by H. A. L. Fisher, the Vice-Chancellor of the University and Gilbert Murray. Murray, whose translations of Greek drama were performed at Somerville in 1912 and 1946, supported Somerville in many ways, including endowing its first research fellowship. A fund was raised as a memorial to Miss Maitland, the principal of Somerville Hall (College from 1894) from 1889 to 1906. This money was used to pay for the oak panelling in Hall. The panelling of the south wall was specially designed to frame the portrait of Mary Somerville by John Jackson. The buildings were constructed on the site of an adjoining building gifted to Somerville by E. J. Forester in 1897 and bought from University and Balliol Colleges for £4000 and £1,400. There was difficulty in the construction of the buildings, which is now thought to have been the result of the outer limit of the Oxford city fortifications running under the site. In 1935, Morley Horder reconstructed the archway which connected Maitland Hall and the south wing of Walton House. In 1947, André Gide gave a lecture in the hall.

Hall and Maitland form the East face of the main quad and are Grade II-listed buildings. The Senior Common Room is situated on the ground floor. The first floor is occupied by the pantry and the hall, in which Formal Hall (called guest night) is held weekly during term time.

Maitland houses few students, being mainly occupied by Fellows' offices and the college IT office. The building is named after Principal Agnes Maitland, and is to the south of Hall.

Penrose

The Penrose block was designed by Harold Rogers in 1925 and its first students were installed in 1927. It is situated at the south western end of the main quadrangle on the site of 119 and 119A Walton Street. A row of poplars had to be removed in 1926 for the construction of Penrose.

The building was refurbished in 2014, with carpets replacing the formerly bare wooden floorboards, and new furniture. Penrose is named for Dame Emily Penrose, the third principal of the college. Penrose houses mainly first year accommodation, with around 30 rooms. Some fellows' rooms are located in Penrose.

Darbishire*

Darbishire Quad

Darbishire Quad was the culmination of a long-standing project to absorb Woodstock Road properties above the Oxford Oratory. In 1920, three houses (29, 31 and 33) were purchased by the college from the vicar of St Giles' Church, Oxford, for the sum of £1,300. The three properties were constructed in 1859 and had been rented by the college prior to their purchase. The adjoining 'Waggon and Horses' was purchased from St John's College, Oxford, in 1923. These buildings were demolished between 1932 and 1933 together with the old Gate House.

Morley Horder was commissioned to build a quadrangle which would fill the space left by the demolished structures with a loan of £12,000 from Christ Church. The porters' lodge and a council room, the New Council Room, were constructed at the entrance to the quad, which housed undergraduate and fellows' rooms. The coat of arms of Somerville and that of co-founder John Percival, first principal Madeleine Shaw-Lefevre and Helen Darbishire were carved by Edmund Ware inside the quadrangle. The archway leading to Hall was reconstructed in 1938.

Originally it was called the East Quadrangle and it was opened in June 1934 by Lord Halifax, who called it 'a notable addition to buildings of varying styles' (varii generis aedificiia additamentum nobile) in the Creweian Oration during the Encaenia. Darbishire was renamed in 1962 in honour of the principal of the college during its construction, Helen Darbishire.

Today Darbishire contains around 50 student rooms mixed with tutors' offices, the college archive and medical room. The offices of the Global Ocean Commission, co-chaired by José María Figueres, Trevor Manuel and David Miliband, were situated in Darbishire as part of a partnership with Somerville, from 2012 to 2016, when the organisation completed its work.

Darbishire Quad is described on the opening page of Gaudy Night by alumna Dorothy L. Sayers and is home to a clock donated by alumna Eleanor Rathbone.

Chapel*

Main article: Somerville College Chapel

Somerville College Chapel

Built largely with funds provided by alumna Emily Georgiana Kemp in 1935, Somerville Chapel reflects the nondenominational principle on which the college was founded in 1879. No religious texts were used for admission and nondenominational Christian prayers were said in college. The chapel's history, architecture, and artworks give valuable insights into the religious, intellectual, and cultural roots of what would subsequently become a global norm. The chapel can be seen as both a manifestation of the aspirations of liberal Christianity in the interwar years, including the advancement of women and ecumenism, and of the contestation of the role of religion in higher education among elites in the same period.

The chapel does not have a chaplain, but a 'Chapel Director' which is in keeping with its undenominational tradition. The chapel provides opportunities for Christian worship in addition to hosting speakers with a multi-faith range of religious perspectives. The chapel also has an excellent mixed-voice choir, the Choir of Somerville College, which tours and produces occasional CDs.

Hostel and Holtby

Hostel is a small block between House and Darbishire, completed in 1950 by Geddes Hyslop. It houses 10 students over three floors. The Bursary is on the ground floor.

Holtby, designed in 1951 and completed in 1956 by Hyslop, is situated above the library extension, adjacent to Park. It has 10 rooms for undergraduates and is named for alumna Winifred Holtby.

Vaughan and Margery Fry & Elizabeth Nuffield House

Designed by Sir Philip Dowson between 1958 and 1966, Vaughan and Margery Fry & Elizabeth Nuffield House (commonly shortened to Margery Fry) are both named for former principals of the college, whilst Elizabeth Nuffield was an important proponent of women's education and along with her husband Lord Nuffield, a financial benefactor of the college. Margery Fry was opened in 1964 by Vijaya Lakshmi Pandit and Vaughan was opened in 1966. Constructed in the same architectural style, with an exterior concrete frame standing away from the walls of the interior edifice, the two buildings sit atop a podium containing shops and an arcaded walkway on Little Clarendon Street.

Vaughan is the larger of the two, with 11 rows to its concrete frame compared to the 8 of Margery Fry. It is a Grade II-listed building. Vaughan contains around 60 undergraduate rooms, which are smaller than those of Margery Fry and house exclusively first year students, along with the junior deans. Vaughan was refurbished in 2013, with new bathroom facilities, including, for the first time, sinks. Beneath the two buildings, a tunnel provides access to Somerville from Little Clarendon Street.

Margery Fry serves as the centre of the post graduate student community at Somerville and contains 24 graduate rooms. Other accommodation for graduate students is provided in buildings adjacent to the College.

Wolfson

Wolfson building

Sir Philip Dowson was commissioned to design a building at the back of the college, to house undergraduates and offices for fellows. Wolfson is, in common with Dowson's other work in Somerville, constructed largely of glass and concrete. It is a Grade II-listed building. A four-storey building, with five bays of each floor, Wolfson boasts impressive views of Walton Street from the rear and Somerville's main quadrangle from the front. Wolfson is named for the building's principal benefactor Sir Isaac Wolfson and opened in 1967 by Principal Barbara Craig, with Harold Macmillan, Dorothy Hodgkin and Lord Wolfson giving speeches.

The ground floor of the building contains the Flora Anderson Hall or FAH and the Brittain-Williams Room, named for the college's most famous mother-daughter alumnae. The room was designed in 2012 by Niall McLaughlin Architects and opened on 29 November 2013 by alumna Baroness Shirley Williams during an event which saw her unveil a portrait of herself, which now hangs in the room. The FAH is used for lectures and events. Notably it hosts college parties known as bops.

Margaret Thatcher Centre and Dorothy Hodgkin Quadrangle*

Named for the alumna-Prime Minister, the MTC comprises a lobby, lecture room and ante room used for many meetings, with disabled access. The lecture room enjoys AV facilities and can accommodate 60 seated patrons. The venue is used for certain term time events and is popular with conferences. A bust of Margaret Thatcher stands in the lobby, and the meeting room contains portraits of Somerville's two prime-minister alumnae, Margaret Thatcher by Michael Noakes and Indira Gandhi by Sanjay Bhattacharyya.

The Dorothy Hodgkin Quad (DHQ) was conceived in 1985 and completed in 1991. It houses mainly finalists and some second year students. The Quadrangle is above the MTC and designed around self-contained flats of two and four bedrooms with communal kitchens. DHQ is named for Somerville's Nobel Prize winning laureate.

Architect Geoffrey Beard's scheme was submitted to the Oxford City Council in 1986 and energies of Sir Geoffrey Leigh and alumna and former Principal Baroness Daphne Park brought support from around the world. The buildings were opened in 1991 by Margaret Thatcher, Dorothy Hodgkin, Principal Catherine Hughes and College Visitor Baron Roy Jenkins.

St Paul’s Nursery

Somerville College was the first Oxford college to provide a nursery for the children of Fellows and staff and is still one of the few colleges to do so. Alumna Dorothy Hodgkin donated much of her Nobel Prize money to the project. St Paul’s Nursery is also open to families who are not connected with the college and cares for 16 children between the ages of 3 months and 5 years.

Radcliffe Observatory Quarter

ROQ East from outside College

ROQ East and West flank the north side of Somerville and overlook the site of the university's principal development, the Blavatnik School of Government. Completed in 2011, the ROQ buildings were the first buildings on the Radcliffe Observatory Quarter and have won 4 awards for their architect Niall McLaughlin. The project was also awarded Oxford City Council's David Steel Sustainable Building Award, being commended for its balancing of Somervillian collegiate heritage with the need for energy efficiency to be a consideration for the new building. Energy efficiency measures include renewable technologies such as solar thermal energy and ground source heat pumps.

The buildings house 68 students and all rooms are en-suite. There are a number of rooms and facilities specifically designed to help those with disabilities, including lifts and adjoining carer rooms. The buildings were made possible by donations of over £2.7 million from over 1000 alumni and friends of the college, and by a significant loan. There is now an unimpeded view of the Observatory.

The Terrace

The most recent construction in Somerville (2013), the college bar in Vaughan replaces the bar in House. The bar is housed in a mainly glass structure, with seating in the college colours of red and black. Following a campaign by the JCR Guinness is now available on tap, and the pool table costs 50p per frame. The college drink, the "Stone-cold Jane Austen", is made from blue VK, Southern Comfort, and Magners cider. Other college drinks are the "Somerville Sunset" and the "College Triple". The college also has its own 'Somerville wine': red, white and sparkling.

Catherine Hughes Building

Named after Somerville's late Principal from 1989 to 1996, the Catherine Hughes Building will be completed in October 2019 and will provide 68 additional bedrooms. The new building, designed by Niall McLaughlin Architects, boasts en suite bathrooms, kitchens and accessible rooms on every floor and a new communal study area for students.

The red brick building will have a frontage on to Walton Street and additional access from the college gardens, aligning with key levels on the adjacent Penrose Building. The bedrooms will be arranged in clusters with kitchens and circulation spaces forming social focal points.

The building's construction has given Somerville sufficient accommodation to allow all students applying from 2017 to live in college for the entirety of their 3 to 4-year undergraduate degree and Somerville is one of only three Oxford colleges able to do so.

Darbishire Quadrangle

Darbishire Quad

Darbishire Quad was the culmination of a long-standing project to absorb Woodstock Road properties above the Oxford Oratory. In 1920, three houses (29, 31 and 33) were purchased by the college from the vicar of St Giles' Church, Oxford, for the sum of £1,300. The three properties were constructed in 1859 and had been rented by the college prior to their purchase. The adjoining 'Waggon and Horses' was purchased from St John's College, Oxford, in 1923. These buildings were demolished between 1932 and 1933 together with the old Gate House.

Morley Horder was commissioned to build a quadrangle which would fill the space left by the demolished structures with a loan of £12,000 from Christ Church. The porters' lodge and a council room, the New Council Room, were constructed at the entrance to the quad, which housed undergraduate and fellows' rooms. The coat of arms of Somerville and that of co-founder John Percival, first principal Madeleine Shaw-Lefevre and Helen Darbishire were carved by Edmund Ware inside the quadrangle. The archway leading to Hall was reconstructed in 1938.

Originally it was called the East Quadrangle and it was opened in June 1934 by Lord Halifax, who called it 'a notable addition to buildings of varying styles' (varii generis aedificiia additamentum nobile) in the Creweian Oration during the Encaenia. Darbishire was renamed in 1962 in honour of the principal of the college during its construction, Helen Darbishire.

Today Darbishire contains around 50 student rooms mixed with tutors' offices, the college archive and medical room. The offices of the Global Ocean Commission, co-chaired by José María Figueres, Trevor Manuel and David Miliband, were situated in Darbishire as part of a partnership with Somerville, from 2012 to 2016, when the organisation completed its work.

Darbishire Quad is described on the opening page of Gaudy Night by alumna Dorothy L. Sayers and is home to a clock donated by alumna Eleanor Rathbone.

Gardens of Somerville College, Oxford

Chapel and Quad in snow

Somerville is the only Oxford college where students may walk on the grass and it has a vast green space behind the unassuming front gate, looked after by two gardeners.

The original site comprised a paddock, an orchard and a vegetable garden and was bounded by large trees. It was home to a donkey, two cows a pony and a pig. The paddock was soon transformed into tennis courts, where huge tents where erected during WWI. During World War Two, large water tanks were dug in the Main Quad and Darbishire Quad, in case or firebombing and the lawns were dug up and planted with vegetables.

In the Main Quad there's a cedar planted by Harold Macmillan in 1976, after an old cedar was victim of a winter storm. Another tree, a Picea likiangensis, was planted in 2007 on the chapel lawn, providing Somerville with an outdoor Christmas tree. The library border of lavender and Agapanthus references the bluestocking reputation of Somerville and the tory blue Ceratostigma willmottianum is planted outside the Margaret Thatcher Centre. Beardtongues, Begonia and 1,200 red and black tulips reflect the college's colours. There are nods to Somerville's long-standing links with India, a strip of Alpine plants in front of Wolfson, a bog garden, herbaceous borders and the emblematic Somerville thistles (Echinops). The western wall of Penrose and the northern wall of Vaughan form two faces of the Fellows Garden, previously kitchen gardens, which is distinct from the main quad and separated from it by a hedge and a wall. The Fellows Garden is home to a sundial, commissioned in 1926, and a garden roller which was a gift from the parents of tutor Rose Sidgwick.

In 1962, Henry Moore lend his item Falling Warrior to the college and Barbara Hepworth lent Core shortly afterwards. Permanent sculptures in Somerville's garden are made by Wendy Taylor, Friedrich Werthmann and Somervillian Polly Ionides.
