The Society of The Diffusion of Useful Knowledge was founded by Lord Brougham to further the education of the lower and middle classes.
The publication was not originally successful and was wound up in 1848. However the rights were acquired by a succession of publishers who modified the plates with latter editions.
Cradock and Baldwin purchased the plates in 1829.
J. & C. Walker was the imprint used by the Walker family of engravers and printers. They produced numerous high-quality geographical maps and nautical charts for a variety of institutions in the nineteenth century. John Walker (1787-1873) held the position of Hydrographer to the East India Company, a position also held by his father and namesake. John worked in partnership with his brothers, Charles and Alexander. The brothers published over 200 maps for the Society for the Diffusion of Useful Knowledge. They produced maps for James Horsburgh and the Admiralty, as well as the influential Indian Atlas.
