Tributes have been paid following the death of UCC history lecturer and researcher Gabriel Doherty.
Mr Doherty was a historian who contributed articles to numerous historical journals and has edited two books de Valera’s Irelands and 1916 – The Long Revolution.
The 56-year-old lecturer has been described as a valued colleague and friend.
Leading the tributes, University College Cork President John O'Halloran said Mr Doherty's loss will be "deeply felt in our community."
"Gabriel was an outstanding historian who deepened our understanding of key moments in Irish history," he said.
"He played a significant role in the recent Decade of Centenaries commemorations and a leading role in research, teaching and examining in his field.
"Much admired and loved, his loss will be deeply felt in our community. We extend our deepest sympathy to his wife Gill, daughters Meabh and Úna, and son Oscar as well as his friends and colleagues," Professor O'Halloran added.
Tánaiste Micheál Martin said he was "shocked and very saddened to hear of Gabriel’s passing".
"He was an outstanding historian based in UCC where he did tremendous work on the War of Independence and Civil War," Mr Martin said.
