Cruise O’Brien follows his cousin Owen into Sandford Park School, which has a predominantly Protestant ethos despite objections from Catholic clergy. He subsequently attends Trinity College Dublin (TCD) before joining the Irish diplomatic corps.
Although he is a fierce advocate of his homeland, Cruise O’Brien is a strong critic of Irish Republican Army (IRA) violence and of what he considers the romanticized desire for reunification with Northern Ireland. His collection of essays Maria Cross: Imaginative Patterns in a Group of Modern Catholic Writers (1952; written under the pseudonym Donat O’Donnell) impresses UN Secretary-GeneralDag Hammarskjöld, who in 1961 appoints him UN special representative in the Congo, later the Democratic Republic of the Congo. He orders UN peacekeeping forces into the breakaway Katanga province, and the resulting scandal forces him out of office. Despite UN objections, he writes To Katanga and Back (1963) to explain his actions.
After serving as vice-chancellor of the University of Ghana (1962–65) and Albert Schweitzer Professor of Humanities at New York University (1965–69), Cruise O’Brien enters Irish politics. He holds a Labour Party seat in Dáil Éireann from 1969 to 1977 and then in the Senate from 1977 to 1979, representing Trinity College, of which he is pro-chancellor (1973–2008).
In 1979, Cruise O’Brien is named editor in chief of the British Sunday newspaper The Observer, but he leaves after three tumultuous years. He remains an active newspaper columnist, especially for the Irish Independent until 2007. His books include States of Ireland (1972) and On the Eve of the Millennium (1995), as well as perceptive studies of Charles Stewart Parnell, Edmund Burke, and Thomas Jefferson.
In early July 1996, in the period of Cruise O’Brien’s involvement as a UK Unionist Party (UKUP) representative in talks at Stormont, he suffers a mild stroke. He recovers well, but is left with anxiety about his recall of names. His last public appearance is on September 7, 2006, to deliver an address on the ninetieth anniversary of the death of Tom Kettle, in the old House of Lords chamber of the Bank of Ireland on College Green.
Mitchell is the younger son of David William Mitchell, owner of a Dublin ironmongery and furniture business, and Francis Elizabeth Mitchell (née Kirby). His elder brother David becomes president of the Royal College of Physicians of Ireland (RCPI) and his sister Lillias is a noted weaver and teacher. He is educated at The High School, Dublin, and Trinity College Dublin (TCD), where he is a scholar in 1933 and receives a gold medal the following year. In 1934 he is appointed assistant to the professor of geology at TCD, and later is lecturer in geology (1940), reader in Irish archaeology (1959) and professor of Quaternary studies – a personal chair (1965). He is an efficient administrator and serves TCD successively as registrar, senior lecturer, and tutor, and after retirement is briefly a pro-chancellor of the university.
Mitchell’s major research focuses on the evolution of Ireland during the last two million years, particularly during the Quaternary since the retreat of the glacial ice over Ireland, and the effect man has had on this landscape. His interest in Quaternary studies begins in 1934, when he is appointed by the Royal Irish Academy (RIA) as an assistant to the Danish botanist and Quaternary geologistKnud Jessen, who uses the distribution of ancient pollen grains to reconstruct vegetational history. From 1940 he publishes a series of papers on topics such as the distribution of Irish giant deer and reindeer remains in Ireland, lacustrine deposits in County Meath, interglacial deposits in southeast Ireland, the palynology of Irish raised bogs, cave deposits, fossil pingos in County Wexford, bog flows, and the deposits of the older Pleistocene period in Ireland. His major study in this field is the documentation (1965) of the vegetational history of Littleton bog, County Tipperary, which has given its name to the present interglacial – the Littletonian warm stage.
Mitchell does not confine his studies to Ireland but also carries out work in Glasgow, Cornwall, and the Isle of Man. In 1957, he helps organise the British Association for the Advancement of Science meeting in Dublin and is later chairman of the Geological Society of London sub-commission on British and Irish Quaternary stratigraphy, which produces a comprehensive report in 1973. He is a frequent broadcaster on radio and a prolific author of academic papers, and in later life writes several acclaimed books, including The Irish Landscape (1976), which goes through two further editions as Reading the Irish Landscape (1986, 1997), and a volume of semi-autobiography, The Way That I Followed (1990).
In 1940, Mitchell marries Lucy Margaret (‘Pic’) (1911–87), daughter of E. J. Gwynn, provost of TCD. They have two daughters. For many years they live at Townley Hall, near Drogheda, County Louth, which had been TCD’s agricultural facility. A 1985 portrait by David Hone is displayed at Trinity College Dublin.
