Gilbert Austin (1753–1837) was an Irish educator, clergyman and author. Austin is best known for his 1806 book on chironomia, Chironomia, or a Treatise on Rhetorical Delivery. Heavily influenced by classical writers, Austin stressed the importance of voice and gesture to a successful oration.
Gilbert Austin was born in 1753 in County Louth, Ireland. Educated at Trinity College, Dublin, Austin received his Bachelor of Arts degree in 1774 and his Master of Arts degree in 1780. After graduating, Austin established a private school in Dublin where he taught the sons of Ireland's elite, including Augustus Frederick FitzGerald, later Third Duke of Leinster (Robb and Thonssen 1966:xv-xvi). Austin inscribed his best-known work, Chironomia, or a Treatise on Rhetorical Delivery, to another of his former pupils, Francis William Caulfeild, Earl of Charlemont.
An active member of the Royal Irish Academy, Austin wrote several scientific papers describing his inventions. In 1789, Austin edited and published a collection of poems by Irish writer Thomas Dermody. Austin also published a number of his sermons, including the collection Sermons on Practical Subjects. Austin began work on his most famous book, Chironomia, in the 1770s but it was not published until 1806.
Austin held several clerical appointments in the Church of Ireland. In 1798, Austin became a minor canon of St. Patrick's Cathedral, Dublin. From 1816 until his death in 1837, Austin was Vicar of Laraghbryan (or Maynooth), a living to which he was presented by his former pupil, the Duke of Leinster. Austin also held the prebendary of Blackrath from 1821 to 1835 (Robb and Thonssen 1966:xvi).
