Christened as William O’Brien, Ó Briain is born at 10 Church Street, North Wall, Dublin, on September 16, 1888, the seventh child of Arthur O’Brien, clerk, and Mary O’Brien (née Christie), who is from County Meath. He takes an interest in the Irish language from an early age and begins learning Irish by himself from a grammar book, as it is not encouraged by his teachers at the Christian Brothers’ O’Connell School nor spoken by his parents. While still at the O’Connell School, he starts using the Irish version of his name. He also attends meetings of the Gaelic League, then attends University College Dublin (UCD) on a scholarship, where he studies French, English and Irish, receiving a BA (1909) and an MA (1910).
UCD decides to start awarding one annual scholarship for overseas travel in 1911, and Ó Briain wins the first one, using it to visit Germany and study under Kuno Meyer and Rudolf Thurneysen. After three years, he returns home, where he rejoins the Gaelic League and begins teaching French at UCD. He also joins the Irish Volunteers then, the following year, Seán T. O’Kelly convinces him to join the Irish Republican Brotherhood (IRB).
Around this time, Ó Briain joins Sinn Féin, and he stands unsuccessfully for the party in Mid Armagh at the 1918 United Kingdom general election in Ireland, taking 5,689 votes. His campaign leads, indirectly, to his arrest and three months in jail in Belfast. In 1920, following his release, he is appointed a judge in the then-illegal republican court system in Galway, and visits both France and Italy to try to source weapons for the Irish Republican Army (IRA). In November 1920, he is arrested in the UCG dining room by Black and Tans, and is imprisoned for thirteen months, first in Galway and then in the Curragh camp in County Kildare, thereby missing the conclusion of the Irish War of Independence. By the time he is released, the Anglo-Irish Treaty has been signed. He supports the treaty and takes no further part in militant activity.
In the newly independent Ireland, Ó Briain remains a professor at Galway. He also stands in the 1925 Seanad election, although he is not successful. He is the founding secretary of the Taibhdhearc na Gaillimhe theatre, also acting in many of its productions, and spends much time translating works from English and the Romance languages into Irish. He stands to become president of UCG in 1945, but is not elected, and in the 1940s and 1950s is best known for his many appearances on television and radio.
From his retirement in 1959, Ó Briain lives in Dublin. In 1974, the National University of Ireland (NUI) confers an honorary doctorate on him. He dies on August 12, 1974, at St. Gabriel’s Hospital, Cabinteely, County Dublin. His funeral to Glasnevin Cemetery is almost a state occasion, with a huge attendance of public figures, and a military firing party at the graveside, where the oration is given by Micheál Mac Líammóir and a lesson is read by Siobhán McKenna. For days after his death, the newspapers carry tributes to his many-sided career and personality. On the one hundredth anniversary of his birth, Proinsias Mac Aonghusa and Art Ó Beoláin write commemorative articles in Feasta.
On September 1, 1921, Ó Briain marries Helen Lawlor, of Dublin, who dies two years before him. The couple’s only child is Eibhlín Ní Bhriain, who is a journalist for The Irish Times and other periodicals.

On September 1, 1921, Ó Briain marries Helen Lawlor, of Dublin, who dies two years before him. The couple’s only child is Eibhlín Ní Bhriain, who is a journalist for The Irish Times and other periodicals.
Mac Aonghusa is the son of Criostóir Mac Aonghusa, a writer and Irish language activist, and Mairéad Ní Lupain, a nurse and native Irish speaker. The eldest of four siblings, he grows up speaking Irish as his first language and allegedly does not learn English until the age of eleven. His parents are left-wing Irish republicans who support Fianna Fáil and associate with the like-minded Máirtín Ó Cadhain and Peadar O’Donnell. His parents split when he is ten years of age. His mother takes his siblings away to Dublin while he and his father remain in Rosmuc, a remote village and part of the Galway Gaeltacht. As a teenager he is educated at Coláiste Iognáid (also known as St. Ignatius College), a bilingual school in Galway.
Upon leaving school, Mac Aonghusa first works as an actor at the Abbey Theatre in Dublin, performing in Irish language productions. In 1952, he becomes involved in Radio Éireann, first as an actor but later as a reader of short stories before advancing to becoming a newsreader, presenter and interviewer. As he advances his career, he works for RTÉ, UTV and BBC television from the 1960s. In 1962, he begins presenting An Fear agus An Sceal (The Man & his Story) on RTÉ television, an Irish language show which sees him interviewing a different guest of note about their life each episode. That same year he wins a Jacob’s Award for An Fear agus an Sceal, which he continues to host until 1964.
As well as attracting awards, An Fear agus an Sceal also brings controversy. Two interviews, one with Máirtín Ó Cadhain, one with Con Lehane, both criticise the measures practised by the Fianna Fáil government during World War II to suppress and imprison Irish republicans. In response, the Fianna Fáil government intervenes with RTÉ, and those episodes are not aired. This is not to be Mac Aonghusa’s only run-in with the Fianna Fáil government. After he recorded a programme in which he questioned the effectiveness of Ireland’s civil defence measures in the face of nuclear war, then Minister for DefenceKevin Boland has the episode suppressed. He once again runs afoul of the Fianna Fáil government when, after criticising the party in his anonymous weekly political gossip column in the Sunday Independent, then Minister for AgricultureNeil Blaney sees to it that the column is dropped. He is not deterred and returns anonymously as “Gulliver” in The Sunday Press and a gossip column on the back page of The Hibernia Magazine.
The latter half of Mac Aonghusa’s 1960s/70s broadcasting career is primarily associated with the Irish language current events show Féach, which he both presents and edits. He resigns from Féach in 1972 following a bitter dispute with the broadcaster and commentator Eoghan Harris.
In 1959, Mac Aonghusa writes a series of six articles for The Irish Times in which he vehemently opposes the Fianna Fáil government’s proposal to abolish single transferable vote in Ireland in favour of first-past-the-post voting. He contends that first-past-the-post voting gives too much influence to party bosses, while proportional representation gives even small minorities representation, preventing them from feeling excluded by the state such as nationalists in Northern Ireland. In the referendum held on the matter on June 17, 1959, voters reject first past the vote by a margin of 2%. Fianna Fáil attempts to repeal proportional representation again in the late 60s, at which point Mac Aonghusa once again throws himself into the fight, leading a group called “Citizens for PR.” In the referendum of 1968, voters reject the first past the post system by over 20%. He later recalls that his defence of proportional representation his greatest achievement in politics.
In the 1960s, both Mac Aonghusa and his wife, Catherine, join the Sean Connolly branch of the Labour Party in Dublin. The branch had established a reputation as a haven for intellectuals who want a branch to themselves away from the many other Labour branches dominated by trade unionists. The branch comes to advocate for expressly socialist policies combined with on-the-ground grass-roots campaigning. Through the Sean Connolly Branch, both he and his wife begin to develop significant influence over the leader of the Labour party Brendan Corish.
In the 1965 Irish general election, Mac Aonghusa stands on behalf of the Labour party in the Louth constituency but is not elected. In 1966, he publishes a book of speeches by Corish, the speeches themselves mostly having been ghostwritten by his wife Catherine. The introduction of the book proclaims that Corish had developed a “brand of democratic republican socialism … broadened by experience and built firmly on Irish‐Ireland roots” and had rid the party of “do‐nothing backwoodsmen”, thereby becoming the “first plausible and respected Labour leader in Ireland”. It is at this same time that he is elevated to vice-chairman of the party. As vice-chair, he tries to convince Corish to stand in the 1966 Irish presidential election. When he fails to do so, he supports Fine Gael‘s Tom O’Higgins in his bid for the presidency. O’Higgins comes within 0.5% of beating the incumbent, an ageing Éamon de Valera.
It was around this same time that Mac Aonghusa becomes active in the Wolfe Tone Societies, a republican organisation linked almost directly to Sinn Féin. He suggests that republicans with “progressive views” should join the Labour party. In 1966, alongside Máirtín Ó Cadhain and other Gaeilgeoirí, he counter-protests and disrupts the Language Freedom Movement, an organisation seeking the abolition of compulsory Irish in the education system. For this, he and his allies are criticised as acting illiberally, while he maintains that those who oppose the Irish language are “slaves” unworthy of tolerance.
Mac Aonghusa’s open disdain for the conservative and trade union wings of the Labour, as well as his open embrace of republican sensibilities and tendency to make pronouncements on Labour policy without first consulting the party’s structures, bring him many internal enemies. An attempt is made to censure him for backing breakaway trade unions, but he is able to survive this. In 1966, he encourages the formation of the Young Labour League, an unofficial youth wing of the party led by Brian Og O’Higgins, son of former Sinn Féin president Brian O’Higgins. Mirroring his own position, the Youth League are Corish loyalists that openly rebel against the views of Labour’s conservative deputy leader James Tully. When the youth league begins publishing their own weekly newsletter, Labour’s administrative council condemns it after discovering material which is “violently” critical of Tully and other Labour conservatives. An ensuing investigation into the newsletter leads to Mac Aonghusa admitting that he had financed it and written some of the content, but not the anti-Tully material. After he refuses to co-operate with further investigations into the matter, he is expelled on January 12, 1967 for “activities injurious” to the party. In the aftermath, he portrays himself a left-wing martyr purged by a right-wing “Star chamber,” a tactic that garners him sympathy. Nevertheless, his expulsion is confirmed at the October 1967 party conference, despite one last appeal. His wife leaves the party alongside him.
In the aftermath of his expulsion from Labour, Mac Aonghusa expresses an interest in the social democratic wing of Fine Gael, which had been developing under Declan Costello since the mid-1960s. However, he does not join the party and instead runs as an independent candidate in the 1969 Irish general election in Dún Laoghaire–Rathdown. When he is not elected, he begins to refocus on the revival of the Irish language and with nationalist politics rather than being elected himself.
Upon the onset of the Troubles, Mac Aonghusa is initially supportive of Official Sinn Féin, however by 1972 he comes to resent them and, through the Ned Stapleton Cumann, their secret influence over RTÉ. During the Arms Crisis in 1970, he supports Charles Haughey and Neil Blaney, who stand accused of arranging to supply weapons to the Provisional IRA, in the pages of the New Statesman and other left‐wing journals. In this time period, he warns editors not to reprint his material in the Republic of Ireland as there is a de facto ban on him, and indeed, official attempts are made to block the transmission of his telexed reports.
Despite his earlier famed stark criticism of Fianna Fáil, Mac Aonghusa’s defence of Haughey leads to a friendship between the two men which results in him becoming one of Haughey’s loudest defenders throughout the rest of his career. His columns in The Sunday Press and Irish language paper Anois are accused of descending into self-parody in their stringent defences of Haughey.
During the 1970s, Mac Aonghusa writes a number of books covering significant figures in Irish republicanism. In order, he releases books on James Connolly, Patrick Pearse, Wolfe Tone and Éamon de Valera. In his work on De Valera, he emphasises what he perceives as the more radical aspects of the Fianna Fáil founder. During 1974 and 1975, he works as a United Nations Special Representative to the Southern Africa region with Seán MacBride, where they involve themselves in the South African Border War, and during which time Mac Aonghusa becomes involved in setting up a radio station in Namibia, linked to the South West Africa People’s Organisation (SWAPO) nationalist party.
In the 1980s, Haughey twice appoints Mac Aonghusa to the Arts Council as well as naming him president of Bord na Gaeilge (1989-93). This is an issue as Mac Aonghusa is already president of Conradh na Gaeilge. Being head of the main Irish language lobbying body as well as the state body responsible for the Irish language has an obvious conflict of interest. In 1991, following the announcement by Haughey that the government is to fund the creation of an Irish-language television station (launched in 1996 as Teilifís na Gaeilge), an elated Mac Aonghusa suggests that Haughey would be “remembered among the families of the Gael as long as the Gaelic nation shall survive.”
In 1992 there are calls for Mac Aonghusa to step down from Bord na Gaeilge after he pronounces that “every respectable nationalist” in West Belfast should vote for Sinn Féin’s Gerry Adams over the Social Democratic and Labour Party (SDLP) candidate Joe Hendron in the 1992 United Kingdom general election as he considers a defeat for Adams “a victory for British imperialism.” Nevertheless, he simultaneously advises voters in South Down to vote for the SDLP’s Eddie McGrady over Sinn Féin. He rails against his detractors at the Conradh na Gaeilge ardfheis that year, declaring that “The mind of the slave, of the slíomadóir, of the hireling and the vagabond is still fairly dominant in Ireland.”
As of 1995, Mac Aonghusa continues to label himself a socialist. In the foreword to the book, he writes about James Connolly that is released that year, he declares that “the abolition of capitalism is essential if the great mass of the people in all parts of the globe are to be emancipated.”
However, with the recent collapse of the Soviet Union in mind, Mac Aonghusa declares that the Stalinist regimes of Eastern Europe have not been socialist and argues that the social democracies of Scandinavia are what James Connolly had envisioned as the desired socialist society. In the same text, he accuses the Irish education system as well as Ireland’s media of obfuscating Connolly’s views on socialism and nationalism.
Mac Aonghusa battles through ill health in his final years but remains able to continue writing a number of books. His last publication, Súil Tharam (2001), comes just two years before his death in Dublin on September 28, 2003.
In 1955, Mac Aonghusa marries Catherine Ellis, a member of the Church of Ireland from Belfast. For her married name, she chooses to use “McGuinness,” the English language equivalent of Mac Aonghusa. Catherine McGuinness goes on to become a Senator and a Judge of the Circuit Court, High Court and Supreme Court over the course of her legal career. Together they have three children together.
Criostóir Mac Aonghusa, teacher, author, critic, and campaigner for the Irish language, is born on December 13, 1905, in Gort an Ghabhainn, Banagher, King’s County (now County Offaly), son of Francis McGuiness (surname thus on his birth certificate), farmer, and his wife, Rosanna (née Egan). He is educated at La Sainte Foi, Banagher, Reachra national school, Shannonbridge, and Naas CBS. He qualifies as a primary school teacher from De La Salle Training College, Waterford, in 1926 and has the distinction of being the first person to sit all exams through the medium of Irish. He graduates BA at University College Galway (UCG) in 1933 and his further education includes a diploma in Spanish literature from University of Barcelona and an MA on the Irish scholar Tomás Ó Máille.
Mac Aonghusa’s teaching career begins in 1926 when he becomes headmaster on Inis Treabhair, County Galway, spending fourteen months there. Afterwards he transfers to Gort Mór, Rosmuc, County Galway, where he continues teaching until 1962. He remains an active member of Cumann na Múinteoirí Náisiúnta throughout his life. Between 1962 and 1972 he is employed as an ad-hoc examiner at the civil service commission. An active member of Fianna Fáil, he helps to organise the party in County Galway in the 1920s and 1930s and is elected a member of Galway County Council in 1934.
Mac Aonghusa is a prominent advocate of the Irish language and together with his close friend Máirtín Ó Cadhain and another Connemara schoolteacher, Seosamh Mac Mathúna, founds Cumann na Gaeltachta to agitate for the civil rights of the Gaeltacht communities and of Irish speakers in general. He is one of the main campaigners for the establishment of the Rath Carn Gaeltacht in County Meath and forms part of the delegation that meets Éamon de Valera on November 11, 1932, and receives from him a promise to provide land in County Meath for that purpose. The Gaeltacht is established in 1935. Mac Aonghusa continues to support the project throughout his life and is involved in further campaigns relating to the area, including the recognition of Rath Carn’s Gaeltacht status. He is also an active member of Conradh na Gaeilge in the 1940s and is later involved in the campaign for the establishment of an Irish-language television broadcasting service.
Mac Aonghusa is a prolific writer and begins publishing short stories and articles from 1926 onward. His contributions appear in An tÉireannach, An Phoblacht, The Irish Tribune, An Stoc, and Ar Aghaidh. From 1948, he is a regular contributor to Feasta and his essays and reviews on Máirtín Ó Cadhain’s works appear in Comhar. He is a member of several literary organisations, including Cumann na Scríbhneoirí and the Galway Literary Society. His first book, An Cladóir agus scéalta eile, appears in 1952. Between 1963 and 1972 he is a contributor to The Irish Press and works also as a literary journalist. An essay on Pádraic Ó Conaire earns him a prize from Acadamh Liteartha na hÉireann.
Mac Aonghusa speaks a number of European languages including German, Spanish, French, Romanian, and Greek and travels widely throughout Europe. In the early 1970s he lives in Russia, and a collection of essays entitled Ó Rosmuc go Rostov is published in 1972. For health reasons he lives in Málaga, Spain, from the middle of the 1970s until 1987. While there, RTÉ produces a documentary on his life entitled Ó Ros Muc go Malaga.
Mac Aonghusa dies on April 9, 1991, in Portiuncula General Hospital, Ballinasloe, County Galway, and is interred in Clonmacnoise. In 1930 he marries Mairéad Ní Lupain, a nurse from Annaghvane in Connemara, and has four children, Proinsias (1933), Micheál (1937), Róisín (1939), and Máirín (1944). The couple separates in the 1940s. Proinsias follows in his father’s footsteps as a writer and journalist and becomes president of Conradh na Gaeilge and chairman of Bord na Gaeilge.
