Maurice Ignatius Keane, or 'Moss' as he came to be known, was born in Currow, County Kerry on July 27, 1948.
Moss Keane was a multi-talented sportsman. Before turning his attention to rugby, he played Gaelic football for his county at Under-21 level and won three Sigerson Cup titles with UCC.
He took to rugby with vigour, revelling in the physicality of the game. After playing for the UCC junior rugby team as 'Moss Fenton', during the GAA's ban on foreign games, he was thrown in at the deep end for Munster - featuring against New Zealand at Musgrave Park in January 1973 - and soon found his feet.
He became a lock forward of high regard, with his talent and skills recognised regularly by Lansdowne, Munster and Ireland.
On January 19, 1974, Moss made his senior debut for Ireland against France at Parc des Princes. He sustained a head wound during the game, leaving him covered in blood.
In a typical show of wit and humour, he later said: "I thought it would be handy if someone had a bucket so we could make a few black puddings!"
He quickly became a cornerstone of the Irish pack, winning the Five Nations Championship in his debut season of 1974. Three years later, he toured New Zealand with the British & Irish Lions, making one Test appearance and playing in 12 tour matches in all.
One of his proudest rugby-playing moments came at Thomond Park on October 31, 1978, as a member of the famous Munster team that defeated the All Blacks 12-0.
Recalling that game, Moss quipped: "To be honest I got a bit of pleasure out of seen their feckin' agony. Andy Haden was crying afterwards and I went up to him and said, 'we're used to this losing, Andy, you're not.' Sure we could write a feckin' thesis on it."
Keane's international career continued to go from strength to strength, and he scored his one and only Test try in a 22-15 home victory over Scotland in February 1980.
Of course, Moss was a key figure for Ireland in their famous Triple Crown-winning campaign of 1982, ever-present in a pack laden with quality...Orr, Fitzgerald, McLoughlin, Lenihan, Keane, Slattery, Duggan and O'Driscoll.
With a nod to Keane's inspirational play during a game, renowned commentator Bill McLaren remarked: "Maurice Ignatius Keane - 18-and-a-half stone of prime Irish beef!"
He went on to become only the third Irish forward to win 50 international caps, after Willie John McBride and Fergus Slattery, when he played against England in February 1984. His 51st and final cap came a few weeks later, against Scotland at Lansdowne Road.
Commenting on the news of Moss' passing, IRFU President Caleb Powell said: "Quite simply Irish rugby has lost one of its most genuine characters and legends of the game.
"Moss had ability on the field that no one could doubt from his record at club, provincial and international level.
"Lansdowne, Munster, Ireland and the British & Irish Lions all benefited from his presence and ensured that his reputation will live long in the memories of not only Irish rugby, but world rugby."
He added: "My own memories of Moss were his great belief in the ethos of the game which was evident in how he related to players from all levels in our club Lansdowne.
"It did not matter whether you were an Ireland international or playing for the third Bs, he always had time for everybody in the club."
