Mícheál Ó Muircheartaigh (; born 20 August 1930) is an Irish Gaelic games commentator for the Irish national radio and television, RTÉ. In a career that has spanned six decades he has come to be regarded as the "voice of Gaelic games." He has been described as a national treasure. His prolific career has earned him a place in Guinness World Records. Early life Mícheál Ó Muircheartaigh was born in Dún Síon just outside Dingle, County Kerry in 1930. Ó Muircheartaigh grew up on the family farm and was educated locally in Dingle. In September 1945 he began studying at Coláiste Íosagáin in Baile Bhúirne in the County Cork Gaeltacht where he was in training to be a teacher. It was at this all-Irish school that his name changed from Michael Moriarty to the Irish version Mícheál Ó Muircheartaigh. In September 1948 he began the final year of his teacher training at St Patrick's College of Education in Drumcondra, Dublin. Broadcasting career In early March 1949 Ó Muircheartaigh, along with ten other students from the college, and several from other colleges, did a test commentary on a hurling game at Croke Park. Each student had to commentate for five minutes in Irish and the most successful would be selected for further commentary work. Ó Muircheartaigh had never seen a game of hurling before in his life. But he knew that those adjudicators judging his commentary were not able to see the game: Ó Muircheartaigh was the one selected and his first assignment was to provide an all-Irish commentary on the 1949 Railway Cup final on St. Patrick's Day. He graduated from St. Patrick's College a little later and also completed a Bachelor of Arts degree (1952) from University College Dublin. He also completed a Higher Diploma in Education (1953). He taught economics, accountancy and Irish in both primary and secondary schools throughout Dublin, the majority of which were run by the Christian Brothers. He continued teaching up until the 1980s, when he became a full-time broadcaster with Raidió Teilifís Éireann. For the early part of his broadcasting career Ó Muircheartaigh commentated on Minor GAA matches, in the Irish language. He also replaced the legendary Micheál O'Hehir when he was not available to commentate. Eventually when O'Hehir was forced to retire in the mid-1980s Ó Muircheartaigh took over as the station's premier radio commentator. He developed his own inimitable style of
