Matthew Stewart

Matthew Stewart FRS FRSE (1717–1785) was a Scottish mathematician and minister of the Church of Scotland. Life He was born in the manse at Rothesay, on the Isle of Bute, on 15 January 1717, the son of Rev Dugald Stewart, the local minister, and his wife, Janet Bannantyne. He was educated at Rothesay Grammar School, then entered the University of Glasgow in 1734, where he studied under the philosopher Francis Hutcheson and the mathematician Robert Simson, the latter from whom he studied ancient geometry. A close friendship developed between Simson and Stewart, in part because of their mutual admiration of Pappus of Alexandria, which resulted in many curious communications with respect to the De Locis Planis of Apollonius of Perga and the Porisms of Euclid over the years. This correspondence suggests that Stewart spent several weeks in Glasgow starting May 1743 assisting Robert Simson in the production of his Apollonii Pergaei locorum planorum libri II, which was published in 1749.
