Dionysius Lardner (3 April 1793 – 29 April 1859) was an Irish scientific writer who popularised science and technology, and edited the 133-volume Cabinet Cyclopædia.
His father was William Lardner, a solicitor in Dublin, who wished his son to follow the same calling. After some years of uncongenial desk work, Lardner entered Trinity College, Dublin in 1812, and obtained a B.A. in 1817 and an M.A. in 1819, winning many prizes. He married Cecilia Flood on 19 December 1815, but they separated in 1820 and were divorced in 1835. About the time of the separation, he began a relationship with a married woman, Anne Maria Darley Boursiquot, the wife of a Dublin wine merchant. It is believed that he fathered her son, Dion Boucicault, the actor and dramatist. Lardner provided him with financial support until 1840. Whilst in Dublin, Lardner began to write and lecture on scientific and mathematical matters, and to contribute articles for publication by the Irish Academy.
In 1828 Lardner was elected professor of natural philosophy and astronomy at University College, London, a position he held until he resigned his professorship in 1831.
Lardner showed himself to be a successful populariser of science, giving talks on contemporary topics such as Babbage's Difference Engine (1834). He was the author of numerous mathematical and physical treatises on such subjects as algebraic geometry (1823), the differential and integral calculus (1825), and the steam engine (1828). He also wrote hand-books on various departments of natural philosophy (1854–1856); but it is as the editor of Lardner's Cabinet Cyclopædia (1830–1844) that he is best remembered.
The Cabinet Cyclopædia eventually comprised 133 volumes, and many of the ablest savants of the day contributed to it. Sir Walter Scott contributed a history of Scotland and Thomas Moore contributed a history of Ireland. Connop Thirlwall provided a history of Ancient Greece, whilst Robert Southey provided a section on naval history. Many eminent scientists contributed as well. Lardner himself was the author of the treatises on arithmetic, geometry, heat, hydrostatics and pneumatics, mechanics (in conjunction with Henry Kater) and electricity (in conjunction with C.V. Walker).
