Desmond John Villiers Fitzgerald, also known as the 29th Knight of Glin, has passed away.
He was the father-in-law of British actor Dominic West.
The Knight of Glin is an ancient Irish noble title handed down from chieftain times.
It is still recognized by Irish governments.
Paying tribute to Mr FitzGerald, the Irish Georgian Society said that Ireland had lost one of its champions of the arts and heritage.
''A passionate man, the Knight tirelessly worked for the future of Irish country houses, their contents, parks and gardens showing the way with the restoration of Glin Castle, and making it home to his collection of Irish paintings, furniture and the decorative arts,'' the society said in a statement.
It said that his ''unique contribution to Irish scholarship, indicated by the depth and breadth of his academic output (books, catalogues, articles), is awe-inspiring.
''Desmond was a man of immense charm as well as erudition; he cherished his beloved wife, Olda, and daughters Catherine, Nesta and Honor.”
His daughter Catherine is married to Mr West.
