Marie-Louise O'Donnell

She revealed in February 2021 that she had contracted COVID-19.

From Foxford, County Mayo, O'Donnell is the daughter and second child of Frank O'Donnell from Foxford (relatives founded the Foxford Woolen Mills, in which her father and uncles worked) and Maire Cranny from Newry, a speech and drama teacher, still working in southern County Dublin as of 2018. The family moved to Dublin but O'Donnell and her brother spent summer and Easter holidays in Mayo.

More recently, in addition to her work with RTÉ and presence in the Seanad, she has appeared as a panellist on TV3's Tonight with Vincent Browne, often featuring in the section of the programme that reviews the following morning's newspapers. She is noted for her persistent and firm defence of Enda Kenny. In March 2018 she sparked criticism after stating teenagers below the age of 18 should “stay away from politics”

In May 2011, Taoiseach Enda Kenny nominated O'Donnell to the 24th Seanad. O'Donnell indicated that the appointment was a surprise, and she did not enter as a member of any party. Kenny again nominated her to the 25th Seanad in May 2016. She ousted David Norris from his role as leader of the Seanad's independent Technical Group on 29 June 2016; however, she is no longer a member of the group.

O'Donnell first rose to prominence in the media as a reporter on RTÉ Radio 1's Today with Pat Kenny in the summer of 2010. However, according to a friend who spoke to The Irish Times: ""It's one of those 'overnight success stories' that was actually years in the making. She trained in radio production and presentation with the BBC and presented programmes for BBC Radio 4." A colleague told the same publication "It's extraordinary the amount of people she knows and counts among her friends. Gay Byrne, Charlie McCreevy, many Fine Gael TDs – she's genuinely close to many people. I accompanied her on a trip to America at one stage and she even had a network there."

O'Donnell commenced PhD studies on university teaching at St Patrick's College, Drumcondra, now the DCU Institute of Education, in 2009.

O'Donnell has also lectured extensively in Ireland, Europe and the US in the areas of education, and Irish culture, especially drama and language. In the early 2000s, she also spent six months as a touring actor across the UK and Ireland, in The Merry Wives of Windsor and King John with the Northern Broadsides company.

O'Donnell served two terms on the board of the National Concert Hall in the 1990s and 2000s. In 2004, she co-founded, with Andy Hinds, the theatrical company Classic Stage Ireland, which produced Shakespeare and ancient Greek drama.

O'Donnell became head of drama at the teacher training college, Carysfort College, where she taught for ten years, until the college's closure in 1988, when she was appointed as a lecturer in the School of Communications at Dublin City University (DCU). At DCU for 23 years, she taught a range of communications and arts courses, including radio documentary making, storytelling and public speaking, and the university sent her for training at the BBC. Research interests included theatrical and radio voice performance, and ancient and modern chorus speech.

Marie-Louise O'Donnell (born 5 September 1952) is an Irish academic, and later broadcaster and politician, who served as a Senator from 2011 to 2020, after being nominated by the Taoiseach. She played a key role in the arts at Dublin City University over a 23-year period, including in the launch of the Helix cultural centre.
