George Hennet (1799-1857) was a surveyor, railway engineer and contractor. In 1827 he was employed by Tessdale & Co. to conduct a survey of Lancashire. The map - when published in 1830 - was very well received. In fact such was the maps success that he was soon engaged, not only, by the great George and Robert Stephenson on the North-West railway, but also by Brunel on the Great Western main-line.
