A Belfast doctor who died at the weekend after falling ill has been described as an "outstanding clinician, a brilliant colleague and a true gentleman".
Dr John Gray, 54, passed away on Sunday evening.
The married father-of-three, who was originally from the Antrim Road area in north Belfast, had worked as a consultant in the emergency departments of the Ulster and Lagan Valley Hospitals.
Dr Gray studied medicine at Queen's University Belfast, qualifying in 1996.
He had already completed a biochemistry degree at Queen's College in Oxford.
He had also undertaken reconciliation work at Corrymeela helping young offenders.
Following his death, his family described him as as "the rock of this family - a man who showed humility, kindness and generosity until his last breath".
"John spent his days saving lives - the rest of the time he made life better for his wife and children who he adored and his wider family.
"It seems a cruel irony that a man who helped so many in their hour of need could not himself be helped when he became seriously ill on Sunday evening.
"While his death leaves a huge hole in our lives that will never be filled, we know his final wish to donate his organs has transformed the lives of others - a final act of generosity that will continue to be an example to his children."
A Committal will take place today at 10am in Holy Trinity Parish Church Graveyard, Ballylesson followed by a Thanksgiving Service in St Andrew's Presbyterian Church, Rosetta Road at 11am.
