William Tunnicliff (fl.1784-96) was a land surveyor and cartographer. In 1787 he began publishing a series of ‘Topographical Surveys’ of individual counties. In that year he was also advertising for employment and it seems that the series was a stop gap to further employment. Indeed the year of this publication of one of Cornwall, 1791, marked the last. His earliest maps are of Lancashire, Staffordshire and Cheshire. Tunnicliff included much industrial information and focused on canals, a feature which was dramatically changing the landscape at the time. Later maps were focused more on the counties to the south and west as here. Quixley (1966) no. 46; Smith ‘The Maps of William Tunnicliff, Reluctant County Map-Maker’, in IMCoS Journal 39 pp. 19-27.
