Christopher (1786–1855) and John Greenwood (1791–1840) were brother cartographers who produced large-scale maps of England and Wales in the 1820s.
In 1818 they formed a partnership in London with sollicitor George Pringle and surveyor George Kemp. The business was highly productive at first, printing many county surveys, but later fell into financial trouble and closed in 1828.
Christopher was imprisoned for debt in 1834 and the brothers' printing plates were sold to pay their debts.
