Richard Horwood

Between 1792 and 1799 Horwood published a Plan of the Cities of London and Westminster the Borough of Southwark and Parts adjoining Shewing every House. At the time this was the largest map ever printed in Britain. After he decided to chart the entire city of London, down to each individual building, Horwood set about soliciting subscriptions to finance the project in 1790. His intention was to publish the complete map within two years, at a scale of 26 inches to the mile. However, the scope of the project was so extensive, and his cost to complete it so high, that rather than taking the estimated two years, the project took almost ten to complete. Despite acquiring royal patronage from King George III, the project suffered financial hardship, making it even more difficult to produce. However, Horwood eventually published the entire map, consisting of 32 sheets (four rows of eight columns). The last sheet was made available in 1799. In 1800 he wrote of the map, in a letter to the Society for the Encouragement of Arts, Manufacture and Commerce: The execution of it has cost me nine years severe labour and indefatigable perseverance; and these years formed the most valuable part of my life. I took every angle; measured almost every line; and after that, plotted and compared the whole work. The engraving, considering the immense mass of work, is, I flatter myself, well done.

Horwood also published a similar large-scale plan of Liverpool, in six sheets, in July 1803. He died on 3 October 1803 in Liverpool, and was buried in Toxteth Unitarian Chapel.
