Richard Turner (bap. 1720, d.1791), Anglican clergyman and educational writer on mathematical and scientific subjects. Turner Matriculated at Magdalen Hall, Oxford and later received an honorary doctorate from Glasgow University (1785). His various introductory guides to book-keeping (1761), gauging (1761), geography and natural phenomena (1763), astronomy and trigonometry (both 1765) reference his clerical position as Vicar at Elmley, in Worcestershire, but also describe him as a teacher of 'geometry, geography and philosophy at Worcester'. This present work is an extensively illustrated introduction to geometry for young scholars, and is remarkably scarce.
