Mícheál Ó Muircheartaigh, an Irish Gaelic games commentator for the Irish national radio and television, RTÉ, is born in Doonshean just outside Dingle, County Kerry, on August 20, 1930. In a career that spans six decades he comes to be regarded as the “voice of Gaelic games.” He has been described as a national treasure. His prolific career earns him a place in Guinness World Records.
Ó Muircheartaigh grows up on the family farm and is educated locally in Dingle. In September 1945, he begins studying at Coláiste Íosagáin in Ballyvourney in the County Cork Gaeltacht where he trains to be a teacher. It is at this all-Irish language school that his name changes from Michael Moriarty to the Irish version Mícheál Ó Muircheartaigh. He says that Irish is his stronger language. In September 1948, he begins the final year of his teacher training at St. Patrick’s College of Education in Drumcondra, Dublin.
In early March 1949, Ó Muircheartaigh, along with ten other students from the college, and several from other colleges, do a test commentary on a hurling match at Croke Park. Each student has to commentate for five minutes in Irish and the most successful is to be selected for further commentary work. Up to this point, he has never seen a game of hurling before in his life. He is the one selected and his first assignment is to provide an all-Irish commentary on the 1949 Railway Cup final on Saint Patrick’s Day.
Ó Muircheartaigh graduates from St. Patrick’s College a little later and also completes a Bachelor of Arts degree from University College Dublin (UCD) in 1952. He also completes a Higher Diploma in Education in 1953. He teaches economics, accountancy and Irish in both primary and secondary schools throughout Dublin, the majority of which are run by the Christian Brothers. He continues teaching up until the 1980s, when he becomes a full-time broadcaster with RTÉ.
For the early part of his broadcasting career, Ó Muircheartaigh commentates on Minor GAA matches, in the Irish language. He also replaces the legendary Michael O’Hehir when he is not available to commentate. Eventually when O’Hehir is forced to retire in the mid-1980s Ó Muircheartaigh takes over as the station’s premier radio commentator. He develops his own inimitable style of commentary, and his accent is unmistakably that of a native Irish speaker. He is a true lover of Gaelic Athletic Association, and it is reflected in the enthusiasm he brings to matches. His unusual turn of phrase makes him a much-loved broadcaster and often imitated character. He becomes particularly famous in Ireland for his unusual turns of phrase in the heat of the moment while commentating. Towards the end of his life, he commentates on RTÉ Radio 1. In 2004, he publishes his autobiography, From Dún Sion to Croke Park.
On March 5, 1988, Ó Muircheartaigh presents the Saturday Live show on RTÉ 1. In 1990, he holds an impromptu interview with Britain’s Prince Edward, after his greyhound had won at the English Greyhound Derby qualifier when he was commentating.
Ó Muircheartaigh’s commentaries for RTÉ Radio 1’s Sunday Sport show win him a Jacob’s Award in 1992. He is also the Parade Grand Marshal for the 2007 St. Patrick’s Festival, having been given the honour by the chairman of the festival in recognition and appreciation of his unique contribution to Irish culture. He is the Parade Grand Marshal for the 2011 St. Patrick’s Parade in Toronto, Ontario, Canada, also in recognition and appreciation of his unique contribution to Irish culture.
On September 16, 2010, Ó Muircheartaigh announces his retirement from broadcasting. The last All-Ireland he commentates on is the 2010 All-Ireland Senior Football Championship Final on September 19, 2010.
On October 29, 2010, it is announced that the 2nd International Rules test at Croke Park would be Ó Muircheartaigh’s final broadcast as commentator on RTÉ Radio 1. The following day he commentates his final commentary alongside RTÉ’s pundit and former Meath footballer Bernard Flynn.
Ó Muircheartaigh is contracted to officiate at the 2011–2012 Volvo Ocean Race finish in Galway where he commentates on the finish to the round-the-world race, giving it a uniquely Irish conclusion. Sailing is his longtime hobby.
Ó Muircheartaigh writes a weekly sports column for Foinse, the Irish-language newspaper free with the Irish Independent each Wednesday. He is invited to read out a piece in Irish and in English at an event called “Laochra” in Croke Park on April 24, 2016, to commemorate the 100th anniversary of the Easter Rising.
In 2007, Ó Muircheartaigh is awarded the UCD Foundation Day Medal. His nephew by marriage, John McGuire, has presented several programmes on RTÉ.
Ó Muircheartaigh dies in hospital in Dublin at the age of 93 on June 25, 2024.
Ó Muircheartaigh is awarded an honorary doctorate by NUI Galway in 1999 for his lifetime service to broadcasting. Shortly after his 90th birthday, he is awarded the only GAA GPA All Stars Award of 2020. No further All Stars can be awarded as competition is suspended due to the COVID-19 pandemic and only completed that December.
