Walter Hussey Burgh (1742–1783 ) was an Irish statesman, barrister and judge; he sat in the Irish House of Commons, and was considered to be one of its outstanding orators. He served briefly as Chief Baron of the Exchequer at the end of his life.
He was born in Kildare, son of Ignatius Hussey of Donore House, near Naas, and his wife Elizabeth Burgh. Elizabeth was the daughter of the leading statesman and architect Colonel Thomas de Burgh, who designed some of the most notable Irish buildings of his era, including Trinity College Library, by his wife Mary Smyth. Walter adopted the surname Burgh as a condition for inheriting the Burgh estate at Drumkeen, County Limerick from his uncle Richard Burgh. Another influential connection was Anthony Foster, Burgh's predecessor as Chief Baron, both of whose wives were members of the Burgh family. In 1767 Walter married his second cousin Anne de Burgh, daughter of Thomas Burgh and sister of the statesman William de Burgh, and they had one son and five daughters. Anne died in 1782.
He was educated at Mr. Young's school at Abbey Street in Dublin, and then at the University of Dublin, where he graduated Bachelor of Arts in 1762; he was an accomplished classical scholar, and had some reputation as a poet. After studying at the Temple, he was called to the Bar in 1769 and within a few years became one of its leaders. He entered the Irish House of Commons in the same year, sitting first for Athy, later for the University of Dublin.
In Parliament he was a close associate of Henry Grattan and a supporter of Grattan's "free trade" programme; he became legendary for his oratory in support of the Irish Patriot Party. At the same time he prided himself on his independence of mind, preferring not to pledge support for any particular policy until he had examined its merits. He acquired as his patron Philip Tisdall, the immensely influential Attorney General for Ireland, who called him "the most promising of the rising young men". At Tisdall's request Burgh was appointed Prime Serjeant in 1776. He resigned the office in 1779, in protest at the continuing restrictions on free trade, after making the celebrated "England has sown her laws as dragon's teeth" speech. After the removal of the restrictions, he agreed to accept office again, and was re-appointed Prime Serjeant in 1782. A month later he was appointed Chief Baron of the Irish Exchequer, but he died the following year at the assizes in Armagh, reportedly from gaol fever.
