# University College Dublin

University College Dublin (commonly referred to, in Ireland, as UCD; Irish: Coláiste na hOllscoile, Baile Átha Cliath) is a public research university in Dublin, Ireland, and a member institution of the National University of Ireland. With 38,417 students, it is Ireland's largest university.
UCD originates in a body founded in 1854, which opened as the Catholic University of Ireland on the feast of St. Malachy with John Henry Newman as its first rector; it re-formed in 1880 and chartered in its own right in 1908. The Universities Act, 1997 renamed the constituent university as the "National University of Ireland, Dublin", and a ministerial order of 1998 renamed the institution as "University College Dublin – National University of Ireland, Dublin".
Originally located at St Stephen's Green and Earlsfort terrace in Dublin's city centre, all faculties later relocated to a 133-hectare (330-acre) campus at Belfield, six kilometres to the south of the city centre. In 1991, it purchased a second site in Blackrock, which currently houses the Michael Smurfit Graduate Business School.
A report published in May 2015 asserted that the economic output generated by UCD and its students in Ireland amounted to €1.3 billion annually. Five Nobel Laureates are among UCD's alumni and current and former staff. Additionally, four Taoisigh (Prime Ministers) and three Irish Presidents have graduated from UCD, along with one President of India.

## History

UCD can trace its history to the institution founded in 1854 as the Catholic University of Ireland. Renamed University College in 1883 and put under the control of the Jesuits in 1883, it became University College Dublin in 1908, a constituent college of the National University of Ireland under the Universities Act.

### Catholic University of Ireland

After the Catholic Emancipation period of Irish history, Archbishop of Armagh attempted to provide, for the first time in Ireland, higher-level education for followers of the Catholic Church and taught by such people. The Catholic hierarchy demanded a Catholic alternative to the University of Dublin's Trinity College, whose Anglican origins the hierarchy refused to overlook. Since the 1780s, the University of Dublin had admitted Catholics to study; a religious test, however, hindered the efforts of Catholics in their desire to obtain membership in the university's governing bodies. Thus, in 1850 at the Synod of Thurles, it was decided to open a university in Dublin for Catholics.
As a result of these efforts, a new "Catholic University of Ireland" opened in 1854 on St Stephen's Green, with John Henry Newman appointed as its first rector. The Catholic University opened its doors on the feast of St Malachy, 3 November 1854. In 1855, the Catholic University Medical School was opened on Cecilia Street.
As a private university, Catholic University was never given a royal charter, and so was unable to award recognised degrees and suffered from chronic financial difficulties. Newman left the university in 1857. In 1861, Bartholomew Woodlock was appointed Rector and served until he became Bishop of Ardagh and Clonmacnoise in 1879. Henry Neville was appointed Rector to replace Woodlock.
In 1880, the Royal University of Ireland was established and allowed students from any college to take examinations for a degree.

### Foundation of University College Dublin

In 1882, Catholic University reorganised, and the St Stephen's Green institution (the former Arts school of the Catholic University) run by the Irish Jesuits, was renamed University College, and it began participating in the Royal University system. In 1883, Fr William Delany SJ was appointed the first president of University College. The college attracted academics from around Ireland, including Fr. Gerard Manley Hopkins and James Joyce. Some notable staff and students at the school during this period included Francis Sheehy-Skeffington, Patrick Pearse, Hugh Kennedy, Hannah O'Leary, Eoin MacNeill, Kevin O'Higgins, Tom Kettle, James Ryan, Douglas Hyde and John A. Costello.
In 1908, the National University of Ireland was founded and the following year the Royal University was dissolved. This new university was brought into existence with three constituent University Colleges – Dublin, Galway and Cork. Following the establishment of the NUI, D. J. Coffey, Professor of Physiology, Catholic University Medical School, became the first president of UCD. The Medical School in Cecilia Street became the UCD Medical Faculty and the Faculty of Commerce was established. Under the Universities Act, 1997, University College Dublin was established as a constituent university within the National University of Ireland framework.
In 1911, land donated by Lord Iveagh helped the university expand in Earlsfort Terrace/Hatch Street/ St Stephen's Green. Iveagh Gardens was part of this donation.

### UCD and the Irish War of Independence

UCD is a major holder of archives of national and international significance relating to the Irish War of Independence.
In 1913, in response to the formation of the Ulster Volunteers, Eóin MacNeill, professor of early Irish history, called for the formation of an Irish nationalist force to counteract it. The Irish Volunteers were formed later that year and MacNeill was elected its Chief-of-staff. At the outbreak of World War I, in view of the Home Rule Act 1914 and the political perception that it might not be implemented, the leader of the Home Rule Party, John Redmond, urged the Irish Volunteers to support the British war effort as a way of supporting Irish Home Rule. This effort on behalf of Home Rule included many UCD staff and students. Many of those who opposed this move later participated in the Easter Rising.
Several UCD staff and students participated in the rising, including Pádraig Pearse, Thomas MacDonagh, Michael Hayes and James Ryan, and a smaller number, including Tom Kettle and Willie Redmond, fought for the British in World War I.
Many UCD staff, students and alumni fought in the Irish War of Independence. Following the signing of the Anglo-Irish Treaty, four UCD graduates joined the government of the Irish Free State.
UCD graduates have since participated in Irish political life – three of the nine Presidents of Ireland and six of the fourteen Taoisigh have been either former staff or graduates.

### Expansion

In 1926, the University Education (Agriculture and Dairy Science) Act transferred the Royal College of Science in Merrion Street and Albert Agricultural College in Glasnevin to UCD. In 1933, Belfield House was purchased for sporting purposes.

### Move to Belfield

In 1940, Arthur Conway was appointed president. By the early 1940s, the college had become the largest third-level institution in the state and the college attempted to expand the existing city centre campus. It was later decided that the best solution would be to move the college to a larger greenfield site outside of the city centre and create a modern campus university. This move started in the early 1960s when the faculty of science moved to the new 1.4 square kilometres (350 acres) park campus at Belfield in a suburb on the south side of Dublin. The Belfield campus developed into a complex of modern buildings and inherited Georgian townhouses, accommodating the colleges of the university as well as its student residences and many leisure and sporting facilities.
One of UCD's previous locations, the Royal College of Science on Merrion Street, is now the location of the renovated Irish Government Building, where the Department of the Taoiseach (Irish prime minister) is situated. University College Dublin also had a site in Glasnevin for much of the last century, the Albert Agricultural College, the southern part of which is now occupied by Dublin City University, the northern part is where parts of the suburb of Ballymun are located.

#### Architecture

The new campus was largely designed by A&D Wejchert & Partners Architects and includes several notable structures, including the UCD Water Tower which was built in 1972 by John Paul Construction. The Tower won the 1979 Irish Concrete Society Award. It stands 60 metres high with a dodecahedron tank atop a pentagonal pillar. The Tower is part of the UCD Environmental Research Station. O'Reilly Hall, opened in 1994, was designed by the Irish architecture firm Scott Tallon Walker.

### 1950–2000

In 1964, Jeremiah Hogan was appointed president and Thomas E. Nevin led the science faculty to move to a new campus at Belfield. Also that year, UCD became the first university in Europe to launch an MBA programme. In 1967, Donogh O'Malley proposed a plan to merge UCD and Trinity. Between 1969 and 1970, the Faculties of Commerce, Arts and Law moved to Belfield. In 1972, Thomas Murphy was appointed president. In 1973, the library opened. In 1980, the college purchased Richview and 17.4 acres and the architecture faculty moved there. In 1981, the Sports Complex opened. In 1986, Patrick Masterson was appointed president.
From the 1980s until his death in January 2021, a solitary, non-verbal homeless man affectionately known as Old Man Belfield became a fixture of campus life at Belfield, becoming well known to students and staff alike. The man, whose real name was Michael Byrne, slept rough on campus for the last 30, if not 40 years, of his life.$^{:29:40}$ Despite not speaking, he came to be "loved and respected by generations of students and staff" and accepted as "part of the UCD community".
During the 1990s, some of the students of Women's Studies, led by Niamh Nolan, petitioned to rename their Gender Studies building after Hanna Sheehy-Skeffington to honour her contribution to women's rights and equal access to third-level education. Her husband Francis Sheehy-Skeffington was himself an alumnus of the university and Hanna of the Royal University, a sister university of UCD. Their campaign was successful and the building was renamed the Hanna Sheehy-Skeffington Building.
In 1990, UCD purchased Carysfort College, Blackrock, and became the location of the Smurfit Graduate school of business. The first student village, Belgrove, opened that year as well. In 1992, the second student village, Merville, opened and the Centre for Film studies was established. In 1993, Art Cosgrove was appointed president. In 1994, O'Reilly Hall was opened.
In Malaysia, UCD and Royal College of Surgeons in Ireland (RCSI) owns a private medical university RCSI & UCD Malaysia Campus (RUMC) within George Town, Penang. Established in 1996, RUMC, as a branch campus of UCD, offers a twinning programme in medicine where students spend the first half of their course in either RCSI or UCD, before completing their clinical years at RUMC.

### 2000s

In 2003, NovaUCD, a Euro Innovation and Technology Transfer Centre, opened. In 2004, Hugh Brady was appointed president. In 2006, UCD Horizons begins. In 2009, Trinity and UCD announce the Innovation Alliance. In 2010, NCAD and UCD form an academic alliance. In 2012 the expanded Student and Sports Centre opened. In 2012, the college closed the athletics track and field facilities and students demanded an apology. In 2013, the UCD O'Brien Centre for Science opened and the UCD Sutherland School of Law opened. It is now the largest Common Law law school in the European Union. In 2015, UCD opened a global centre in the US. In 2019, UCD became the first Irish university to launch a Black Studies module, coordinated by Dr Ebun Joseph and Prof Kathleen Lynch. In March 2022 Prof Andrew Deeks resigned to take up the role of vice-Chancellor at Murdoch University, in Perth, Western Australia. Prof Mark Rogers was appointed acting president.

### Societies

As of 2022, UCD had more than seventy student societies, including large-scale party societies such as Ag Soc, Arts Soc, Commerce and Economics Society, ISS (and its subgroup AfricaSoc), INDSoc (Indian Society) and MSoc (Malaysian Society) who have the largest student communities of Indian and Malaysian students in Ireland. There are also religiously interested groups such as the Christian Union, the Islamic Society, the Atheist and Secular Society, a television station Campus Television Network, academic-oriented societies like the Economic Society, UCD Philosophy Society, Mathsoc, Classical Society, and An Cumann Gaelach, an Irish-language society and such charities as St. Vincent de Paul, UCDSVP. There are two main societies for international students, ESN UCD (part of the Erasmus Student Network) and the International Student's Society. The UCD Dramsoc is the university's drama society.
The oldest societies include the Literary and Historical Society (known as the L&H and which dates itself to 1855), the Commerce & Economics Society (in its 110th session as of 2022), and the Law Society (founded in 1911). At the start of the 2012/13 Academic Year, the L&H had a membership of 5,143 becoming the largest student society in UCD and in Europe.
The Commerce & Economics Society, which describes itself as "Ireland's largest and oldest business orientated university society", was originally a debating society. By 1999 it was, according to an article in the Irish Times, the "largest college society in UCD, Ireland and the British Isles". The society runs a number of events, including the formal black-tie 'Comm Ball', as well as mock interviews and networking events. Its notable former auditors and members include ex-Taoisigh Charles Haughey and Garret FitzGerald.
In competitive debating, the L&H and Law Society have represented the college several times, with the L&H securing 11 team wins and 12 individual wins in the Irish Times Debate and the Law Society achieving 2 team wins and 2 individual wins. The two societies have also been successful at the UK and Ireland John Smith Memorial Mace (formerly The Observer Mace) with the L&H winning 5 titles and Law Society 2 titles. UCD has hosted the World University Debating Championships twice, including the 2006 event.
A number of UCD societies engage in voluntary work on-campus and across Dublin. For example, the UCD Student Legal Service is a student-run society that provides free legal information clinics to the students of UCD.
Irish political parties are also represented on campus, with chapters of Ógra Fianna Fáil, Young Fine Gael, Ógra Shinn Féin, the Young Greens, People Before Profit and Labour Youth. UCD's "flagship instrumental ensemble", the University College Dublin Symphony Orchestra, was celebrating its 20th anniversary season as of 2022/2023.

### Student publications and media
#### Newspapers

UCD has two student newspapers currently published on campus, the broadsheet University Observer and the tabloid College Tribune

##### The University Observer

The University Observer has won several awards, including five "newspaper of the year" awards at Ireland's National Student Media Awards. Founded in 1994, its first editors were Pat Leahy and comedian Dara Ó Briain. Several figures in Irish journalism have held the position of editor including The Irish Times political editor Pat Leahy, RTÉ News reporter Samantha Libreri, and Virgin Media News political correspondent Gavan Reilly. In 2001, in addition to several Irish National Student Media Awards, the University Observer took the runner up prize for "Best Publication" at the Guardian Student Media Awards in London.
The main sections within the paper are campus, national and international news, comment, opinion and sport. Each issue is also accompanied by an arts and culture supplement called O-Two, with music interviews, travel, fashion and colour pieces.

##### College Tribune

The College Tribune was founded in 1989, with the assistance of political commentator Vincent Browne. Then an evening student at UCD, Browne noted the lack of an independent media outlet for students and staff and set about establishing a student newspaper. The paper was initially established with links to the Sunday Tribune, though over time these links faded and ultimately, the Tribune would outlast its national counterpart. The paper supports itself financially through commercial advertising in its print edition, and maintains editorial independence from both university authorities and the Students' Union. The Tribune has been recognised on a number of occasions at the National Student Media Awards, and won Student Newspaper of the Year at the 1996 USI & Irish Independent Media Awards.
College Tribune sections include news, sport, features, arts, film and entertainment, music, fashion, business, and politics & innovation. It also has an arts culture supplement, The Trib, and a satirical 'paper within a paper', The Evil Gerald.

#### Radio and television

UCD also has a student radio station, Belfield FM, broadcasting throughout the academic year online on the station's website. The station is independently run by the UCD Broadcasting Society and has produced well known Irish radio presenters such as Ryan Tubridy and Rick O'Shea (of RTÉ fame) and Barry Dunne of 98FM. Belfield FM is the successor to UCD FM, which was operated within the entertainment office of the students' union as a service for students. Initially launched in 1992, the station rebranded in 2000 and has operated since then under the current name. As a result of the implementation of the students' union's new constitution at the beginning of the 2012 / 2013 academic year, the station now operates as a student society.

### UCD scarf colours

In later years, students have been given a scarf of St Patrick's blue, navy and saffron at the President's Welcome Ceremony when they are officially welcomed. These colours have replaced "Faculty" colours and are now worn at graduation also.

## In popular culture
### In literature

James Joyce's novel A Portrait of the Artist as a Young Man is partially set in UCD (when it was sited on Earlsfort Terrace) where Stephen Dedalus (now the name of the IT building) is enrolled as a student. Joyce's posthumously published autobiographical novel Stephen Hero contains stories of his time in UCD. Flann O'Brien's novel At Swim-Two-Birds features a UCD student who writes a meta-novel wherein the author is put on trial by the characters of his novel. Maeve Binchy's novel, Circle of Friends, deals with three female friends starting college in UCD in the 1950s. However, shots of Trinity College were used in the 1995 film. The second Ross O'Carroll-Kelly novel, The Teenage Dirtbag Years, follows the titular character as he enters UCD.

### In music and film

Christy Moore wrote a tongue in cheek song about UCD's Literary and Historical Society called "The Auditor of the L and H".
Conor McPherson's third film Saltwater was filmed in Belfield, UCD. In Boston Legal, Season 2, Episode 21 "Word Salad Day", there is a reference to a fictional study from University College Dublin that "found that the effects of divorce on children are far more damaging than the death of a parent".
