The Society for the Diffusion of Useful Knowledge (SDUK)
The Society published books that were deemed to be of high educational worth but produced them at a price that was affordable. Their greatest publication, most probably, was their atlas of the world, entitled “Maps of the Society for the Diffusion of Useful Knowledge”. Benevolent societies whose intentions were to disseminate knowledge were a distinguishing feature of the Victorian age. This Society was founded in 1827 by John, Earl Russell and Henry Brougham, later Lord Chancellor of England. Earl Russell was an M.P. who was responsible for setting up an inspectorate for schools and an additional grant of 30,000 pds for education.
John Walker (1787 - April 19, 1873) was a British hydrographer & geographer active in London during the 1800s. Walker published both nautical charts and geographical maps. His nautical work is particular distinguished as he was an official hydrographer for the British East India Company. Walker's maps mostly published after 1827, was primarily produced in partnership with his brother Charles Walker under the imprint J. and C. Walker. Among their joint projects are more than 200 maps for the influential Society for the Diffusion of Useful Knowledge Atlas (SDUK). They published numerous charts for the British Admiralty. Both Walker's died in the 1870s.
