Colonel Sir Charles Arden Close was Director-General of the Ordnance Survey from 1911 to 1922. A man of immense stature and accomplishment in his time, he was, moreover, a link between the traditions of the nineteenth century and the future practices of the twentieth. 

He was responsible for the inception of many of the maps now sought after by collectors, and injected into OS a measure of geodetic excellence which it had not experienced since the days of Clarke in the 1850s. He is perhaps best known today for his book 'The Early Years of the Ordnance Survey', of which it has been said that 'in writing these historical and individual notes, Close performed a service to the Ordnance Survey as well as to British geodesy and British surveyors'. Much of the book was based on the papers collected by Major-General Thomas Colby, Superintendent of OS from 1820 to 1846, and of which Close had custody. He presented the papers to OS in 1927, but they were destroyed in the Second World War.
