William Mudge was appointed in 1791 to the ordnance trigonometrical survey and became superintendent of the survey in 1798 and in that same year was also elected as a Fellow of the Royal Society. Shortly afterwards he completed the first ever measurement of an arc of meridian stretching from Dunnose on the Isle of Wight to Clifton in Yorkshire.
