LEYBOURN, THOMAS (1770–1840), mathematician, born 9 April 1770, edited the ‘Mathematical Repository’ from 1799 to 1835. In 1802 he published ‘A Synopsis of Data for the Construction of Triangles,’ and in 1817 ‘A Collection of Solutions of the Mathematical Questions proposed in the “Ladies' Diary” from its commencement to 1816.’ He was appointed in 1802 a teacher of mathematics in the Royal Military College, Sandhurst, and retired on a pension from the office of senior professor of mathematics in December 1839, after nearly forty years' service. He died at Sandhurst on 1 March 1840. 

LEYBOURN, WILLIAM (1626–1700?), mathematician, born in 1626, was a teacher of mathematics and professional land surveyor in London. He is said to have begun life as a printer; but as early as 1648 he appears as joint author with [q. v.] of the first book on astronomy written in English; its title was ‘Urania Practica,’ and it was adapted to the comprehension of beginners. Its authors are styled ‘practitioners in the mathematicks.’ It reached a second edition in 1649, and was criticised by Jeremie Shakerley in ‘The Anatomy of Urania Practica,’ 1649; the authors replied in ‘Ensfictum Shakerlæi, or the Annihilation of Mr. Jeremie Shakerley,’ 1649. In 1650 appeared ‘Planometria, or the Whole Art of Surveying of Land,’ by ‘Oliver Wallinby,’ the pseudonym being a mere transposition of the letters of Leybourn's name. This was republished with additions and acknowledged by its author in 1653, under the title ‘The Compleat Surveyor.’ It passed through four editions in his lifetime; a fifth edition appeared in 1722, edited by Samuel Cunn, who says in the preface: ‘The author of this treatise was frequently employed in surveying, measuring, and mapping gentlemen's estates, as evidently appears from the several draughts by him drawn and to be met with
