Christopher(1786–1855) and John Greenwood(fl.1821–1840) were brother cartographers who produced large-scale maps of England and Wales in the 1820s. Their partnership began in 1821, using the imprint "C.&J. Greenwood".
Christopher was born in Wakefield, Yorkshire, and moved to London in 1818. His first map publication (of Yorkshire) was based on his own surveying.
In 1759 the Society for the Encouragement of Arts, Manufacture and Commerce announced a prize of £1,000 for an original survey of England at a scale of one-inch-to-the-mile (approx. 1:63,000). The first recipient of the award was Benjamin Donn, whose map of Devon, completed in 1765, had taken five and a half years to produce. Maps of many counties followed.
The Greenwoods' intention was for a series of maps of the whole country at a one-inch scale. They did not achieve this, largely because of competition from the newly founded Ordnance Survey, but their output includes superb maps that were finely drafted and elegantly engraved. Between 1817 and 1830 they produced a series of splendid large-scale folding maps of most of the counties based on their own surveys.
Their Atlas of the Counties of England(c. 1834) was beautifully engraved and decorated with large vignettes of prominent buildings of the county. The maps were engraved on steel, a more durable medium than copper. Some of them were issued uncoloured, but most are now found with full-wash colour across the body of the map.
