Born in Dublin, O'Conor attended Belvedere College in that city. During his early Dublin studies, his main piano teacher was J. J. O'Reilly. Later he was awarded an Austrian Government scholarship that enabled him to study in Vienna with the renowned pedagogue Dieter Weber. He also made a special study of Beethoven with the legendary German pianist Wilhelm Kempff. In 1973 O'Conor was unanimously awarded First Prize at the International Beethoven Piano Competition in Vienna which launched his international career, and in 1975 he won First Prize at the Bösendorfer Competition.
O'Conor has given recitals in many of the world's most famous halls including New York's Lincoln Center, the Kennedy Center in Washington, the Wigmore Hall and South Bank Centre in London, the Musikverein in Vienna, the Dvorak Hall in Prague and the Bunka Kaikan in Tokyo.
He has performed in Europe, North America, Asia, Africa, Australia and New Zealand, and has appeared with such orchestras as the London Symphony, Royal Philharmonic, Czech Philharmonic, Vienna Symphony, l'Orchestre National de France, the Scottish and Stuttgart Chamber Orchestras, the Israel Camerata, the NHK, Yomiuri, Kyushu, Kyoto and Sapporo Symphonies in Japan, the KBS Symphony in South Korea, the Singapore Symphony, the New Zealand Symphony and the orchestras of Cleveland, San Francisco, Atlanta, Boston, Dallas, Detroit, Indianapolis, Milwaukee, Seattle, Montreal, Toronto, Tampa and Washington DC in North America. He has performed the complete sonatas of Beethoven in a cycle of 8 recitals in one season on a number of occasions in many venues including Dublin (National Concert Hall), New York (Metropolitan Museum of Art) and Boston (Gardner Museum).
O'Conor has made more than 20 recordings for the Telarc label including the complete Beethoven Piano sonatas, and the complete Beethoven Bagatelles, which latter was cited by the New York Times as the best recording of these works; the five Beethoven Piano concertos, released in 2008; four volumes of Mozart piano concertos with Sir Charles Mackerras and the Scottish Chamber Orchestra; numerous works of Schubert including the late A major Sonata, the complete Impromptus and Moments Musicals, Waltzes and the Trout Quintet with the Cleveland Quartet; and two volumes of short piano pieces entitled Piano Classics and Autumn Songs. An avid proponent of his fellow countryman John Field, he has recorded most of the composer's major works including the complete Concertos, Sonatas and Nocturnes. His recording of Field's Nocturnes was featured on Billboard Magazine's classical charts for many weeks. He has also recorded a popular CD of his favourite Irish Airs (including "Danny Boy", "Come back to Erin" and "The Banks of my own lovely Lee") on the After9 label (called Irish Classics).
International Piano competitions
O'Conor was a co-founder of the Dublin International Piano Competition of which he is Artistic Director and Chairman of the Jury. He has been invited to serve on the juries of many international piano competitions including those in Leeds, Moscow (Tchaikovsky), Vienna (Beethoven), Warsaw (Chopin), Tel Aviv (Rubinstein), Beijing, Shanghai, Munich, Bolzano (Busoni), Cologne, Vevey (Clara Haskil), Cleveland (Cleveland International Piano Competition), Salt Lake City (Gina Bachauer), Sydney, Pretoria, London, College Park (William Kapell), Valencia (Jose Iturbi) and Seoul. He is currently involved in the organisation of the 2015 Dublin International Piano Competition.
O'Conor currently holds the position of Professor of Piano and Distinguished Visiting Artist at Shenandoah Conservatory (near Washington, D.C.), and retired as Director of the Royal Irish Academy of Music in September 2010 although he continues to teach there regularly.
His salary package of €225,000 for his part-time position as director and teacher at the Royal Irish Academy of Music came under criticism by the Comptroller and Auditor General on 3 December and was described as inappropriate in the context of public service norms and for the operation of a modern organisation by the secretary general of the Department of Education, Brigid McManus. Fine Gael spokesman on education called on O'Conor to repay all money received which "appear to be in breach of public service guidelines". In a meeting of the Public Accounts Committee on 20 January 2011 it was recognised that in return for his salary O'Conor raised €3.4 million, increasing the RIAM's overall income from private sources through fundraising efforts. As a result of a subsequent government investigation, Mr. O'Conor was completely exonerated of all blame in the matter and was called a "National Treasure" by the chairman of the Public Accounts Committee.
Since 1997 he has taken on the mantle of Kempff, and gives the annual Beethoven Interpretation Course in Kempff's own villa in Positano, Italy where Kempff gave the course from 1957. A television programme made in 2007 (the 50th anniversary of the founding of the course by Kempff) is now available on YouTube entitled 'Beethoven Bootcamp'.
He gives masterclasses and lectures in many of the places he performs as well as in many of the major music institutions including the Juilliard and Manhattan Schools in New York, Harvard, Yale, Temple, Rutgers, Indiana and Seattle Universities, the Hamamatsu Piano Academy in Japan, the National University of the Arts in Korea, the Australian National Academy and the Sydney Conservatorium in Australia and the Royal Academy of Music and the Guildhall School of Music in London.
For his services to music O'Conor has been awarded Honorary Doctorates by the National University of Ireland, Trinity College Dublin, Dublin Institute of Technology and Shenandoah University, and an Honorary Fellowship by the Royal Irish Academy of Music. He has been decorated with the title "Officier de l'Ordre des Arts et des Lettres" by the French Government, has been awarded the "Ehrenkreuz für Wissenschaft und Kunst" by the Austrian Government and has also been decorated by the Italian and Polish governments. In 2011 he was awarded the "Order of the Rising Sun" by the Emperor of Japan.
