William Kirby (19 September 1759 – 4 July 1850) was an English entomologist, an original member of the Linnean Society and a Fellow of the Royal Society, as well as a country rector, so that he was an eminent example of the "parson-naturalist". The four-volume Introduction to Entomology, co-written with William Spence, was widely influential. Family origins and early studies Kirby was a grandson of the Suffolk topographer John Kirby (author of The Suffolk Traveller) and nephew of artist-topographer Joshua Kirby (a friend of Thomas Gainsborough's). He was also a cousin of the children's author Sarah Trimmer. His parents were William Kirby, a solicitor, and Lucy Meadows. He was born on 19 September 1759 at Witnesham, Suffolk, and studied at Ipswich School and Caius College, Cambridge, where he graduated in 1781. Taking holy orders in 1782, he spent his entire working life in the peaceful seclusion of an English country parsonage at Barham in Suffolk, working at the parish church of St Mary's for 68 years, first as curate, then as rector from 1797. He assisted in the publication of pamphlets against Thomas Paine during the 1790s. Kirby was brought to the study of natural history by Nicholas Gwynn (a friend of Boerhaave's), who introduced him to Sir James Edward Smith in 1791. Soon afterwards, he corresponded with Smith, seeking advice on the foundation of a natural history museum at Ipswich. Among his early friends were the naturalists Charles Sutton and Thomas Marsham, with whom he made lengthy scientific excursions, as later with William Jackson Hooker and others, becoming a leading parson-naturalist. His name appears on the original list of Fellows of the Linnean Society. He delivered the first of his many papers on 7 May 1793, on Three New Species of Hirudo (Linn. Trans. II, 316). Major publications Kirby produced his first major work, the Monographia Apum Angliae (Monograph on the Bees of England), in 1802. His purpose was both scientific and religious: 'The author of Scripture is also the author of Nature: and this visible world, by types indeed, and by symbols, declares the same truths as the Bible does by words. To make the naturalist a religious man – to turn his attention to the glory of God, that he may declare his works, and in the study of his creatures may see the loving-kindness of the Lord – may this in some measure be the fruit
