James Six (ca. 1758-1786) was the son of the Canterbury thermometer inventor of the same name. A fellow of Trinity College, Cambridge, Six was employed as a tutor to John Thomas Stanley (later Baron Stanley of Aldersley), and accompanied him on an extensive Grand Tour. Six became ill in Naples after ascending Vesuvius, and died in Rome in December, 1786 despite being treated with laudanum by the Duke of Gloucester's physician.
