DOUGHARTY, JOHN (1677–1755), mathematician, was an Irishman, and kept a writing and arithmetic school at Worcester for fifty-five years. He also taught the higher branches of mathematics. His ‘General Gauger,’ 12mo, London, 1750, came to a sixth edition in the same year. Another work from his pen was ‘Mathematical Digests, containing the Elements and Application of Geometry and plain Trigonometry … with a Supplement, containing Tables for finding the Mean Times of the Moon's Phases and Eclipses.’ He died at Worcester 11 Jan. 1755, aged 78, and was buried in the centre of the area of the cloisters of the cathedral. His two sons, Joseph and John, were successful surveyors. The former published an accurate ichnography of the cathedral, reproduced in Thomas's ‘Survey,’ 1736; while John is known by his plan of Worcester, 1742, a drawing of the guildhall of that city, and ‘an exact plan’ of Kidderminster, 1753.
