EDGEWORTH, RICHARD LOVELL (1744-1817), British writer, was born at Bath on the 31st of May 1744. The greater part of his life, however, was spent at Edgeworthtown, or Edgeworthstown, in the county of Longford, Ireland, where the Edgeworth family had been settled for upwards of 150 years. He was of gentle blood--his father being the son of Colonel Francis Edgeworth, and his mother, Jane Lovell, being the daughter of Samuel Lovell, a Welsh judge. Richard's mother taught him to read at a very early age; and from childhood he had a strong love for mechanical science. The Rev. Patrick Hughes initiated him in Lilye's _Latin Grammar_--an office he also performed for Goldsmith, who was born on the property of the Edgeworths--and his public education began, in August 1752, in a school at Warwick. He subsequently attended Drogheda school, then reputed the best in Ireland; and, after spending two years at a school in Longford, entered Trinity College, Dublin, in April 1761, but was transferred to Corpus Christi College, Oxford, in October of the same year. While still at college, he made a runaway match, marrying at Gretna Green, Anna Maria, one of the daughters of Paul Elers of Black Bourton, Oxfordshire, an old friend of his father. His eldest son was born before Edgeworth reached his twentieth birthday, and his daughter Maria in 1767. Shortly after the birth of his son, he and his wife went to Edgeworthstown, but in 1765 they took a house at Hare Hatch, near Maidenhead. Edgeworth devoted much time to scientific reading and experiments; and he made an attempt to establish telegraphic communication (_Memoirs_, 2nd edition, i. 144). He also invented a turnip-cutter, a one-wheeled chaise and other contrivances. In the pursuit of his mechanical inventions he visited Erasmus Darwin at Lichfield, where he met Anna Seward, and her cousin, Honora Sneyd. His home was now at Hare Hatch, in Berkshire, where he endeavoured to educate his son according to the method explained in Rousseau's _Émile_. In later life, however, the ill-success of this experiment led him to doubt many of Rousseau's views (_Memoirs_, ii. 374). At the same time he kept terms at the Temple, and formed the greatest friendship of his life with Thomas Day, the author of _Sandford and Merton_, which was written at Edgeworth's suggestion. In 1769, on the death of his father, he gave up the idea of being a barrister; but, instead of immediately settling on his Irish estate, he spent a considerable time in England and France, mainly in Day's company. In Lyons, where he resided for about two years, he took an active part in the management of public works intended to turn the course of the Rhone. He was summoned to England by the death of his wife (March 1773), with whom he was far from happy. Edgeworth hurried to Lichfield, to Dr Erasmus Darwin's, and at once declared his passion for Honora Sneyd, which had been the cause of his flight to France two years before.
