Hardy co-operated with
Lord Charlemont in the establishment of the
Royal Irish Academy at Dublin in 1786, and in 1788 contributed to its publications a dissertation on some passages in the
Agamemnon of
Æschylus. The publication of some of the writings of Charlemont, who had died in 1799, was planned by Hardy; and he then undertook a biography at the suggestion of
Richard Lovell Edgeworth. He received assistance from the Charlemont family, Grattan and others. It appeared in London in 1810,
Memoirs of the Political and Private Life of James Caulfield, Earl of Charlemont, Knight of St. Patrick. The memoirs are not completely accurate. An edition with little alteration was issued in London in 1812, in two volumes. ==Notes==
