Postlethwayt, Malachy (DNB00)
POSTLETHWAYT, MALACHY (1707?–1767), economic writer, born about 1707, was elected F.S.A. on 21 March 1734. He devoted twenty years to the preparation of ‘The Universal Dictionary of Trade and Commerce,’ London, 1751, fol. (3rd edit. London, 1766, fol.; 4th edit. London, 1774, fol.), a translation, with large additions, from the French of J. Savary des Brulons. Postlethwayt collected much information, freely plagiarising other writers, but presented his results without method or conciseness. He died suddenly, ‘as he had often wished,’ on 13 Sept. 1767, and was buried in Old Street churchyard, Clerkenwell.
