Richard Kirwan, LL.D, FRS, FRSE MRIA (1 August 1733 – 22 June 1812) was an Irish geologist and chemist. He was one of the last supporters of the theory of phlogiston. Kirwan was active in the fields of chemistry, meteorology, and geology. He was widely known in his day, corresponding and meeting with Lavoisier,

Life and work

Richard Kirwan was born at Cloughballymore, County Galway, the second son of Martin Kirwan of Cregg (d.1741), and his wife, Mary French (d.1751). He was a descendant of William Ó Ciardhubháin and a member of The Tribes of Galway. Part of his early life was spent abroad, and in 1754 he entered the Jesuit novitiate either at St Omer or at

Kirwan married "Miss Blake" in 1757, but his wife only lived eight more years. The couple had two daughters, Maria Theresa and Eliza. In 1766, having conformed to the established religion (

, but in 1768 abandoned practice in favour of scientific pursuits. During the next nineteen years he resided chiefly in London, enjoying the society of the scientific men living there, and corresponding with many savants on the continent of Europe, as his wide knowledge of languages enabled him to do with ease. His experiments on the specific gravities and attractive powers of various saline substances formed a substantial contribution to the methods of analytical chemistry, and in 1782 gained him the Copley medal from the

. This work, translated by Marie-Anne Pierette Paulze, was published in French with critical notes by Lavoisier and some of his associates; Kirwan attempted to refute their arguments, but they proved too strong for him, and he acknowledged himself a convert in 1791. There is evidence to suggest that Kirwan was a member of the Society of the United Irishmen, a revolutionary republican organisation in 18th century Ireland. The United Irishmen were founded as a reformist club by a group of Irish radical Protestants and Presbyterians in 1791, influenced by the American and French revolutions.

and the Act of Union. At the time of the Union, Kirwan refused a baronetcy and died in Dublin in June 1812, and was buried there in St. George's Church, Lower Temple Street.

Eccentricities

Various stories are told of Kirwan's eccentricities as well as of his conversational powers. It is said that flies "were his especial aversion; he kept a pet eagle, and was attended by six large dogs." Kirwan disliked flies and paid his servants for each time they were killed. He also disliked late visitors and had his door-knocker removed each evening at seven o'clock.Foster, John Wilson. (1998). ''Nature in Ireland: A Scientific and Cultural History''. McGill-Queen's University Press. p. 93. Kirwan suffered from
