Major General 'Sir Henry James' FRS MRIA RE (1803 – 1877) was the director-general of the Ordnance Survey, the British government mapping agency, from 1854 to 1875. Sir Henry was described by the agency itself as "perhaps Ordnance Survey's most eccentric and egotistical Director General".^[1]
Henry James joined the Royal Engineers with the rank of Lieutenant in 1831. He was promoted to captain in 1846 and then to Colonel in 1857. He joined the staff of the Ordnance Survey in 1827 and was local superintendent for the Geological Survey of Ireland from 1843 to 1846. Having transferred to Admiralty employment in 1846, James returned to the Ordnance Survey in 1850 and was the director-general between 1854–1875. In addition he held the post of Director of the topographical and statistical department of the War Office between 1857 and 1870.
James introduced photography to the Ordnance Survey's processes in 1855. He claimed to have invented photozincography, a photographic method of producing printing plates. In fact, the process had been developed by two of his staff.^[2]
