Until the mid 19th century, Horsforth was an agricultural community but it expanded rapidly with the growth of the nearby industrial centre of Leeds. A tannery business was founded at Woodside in about 1820 by the Watson family. It was on the eastern edge of their small farm, and memorialised by "Tanhouse Hill Lane". The business became a soap manufacturer and moved to Whitehall Road in Leeds in 1861 and under the chairmanship of Joseph Watson junior, created Baron Manton in 1922, as Joseph Watson & Sons Ltd, became the largest soap supplier to the northeast of England, second in size nationally only to Lever Brothers. Industrially, Horsforth has a history of producing high-quality stone from its quarries. Not only did it supply Kirkstall Abbey with building materials and millstones in the medieval period, it provided the stone for Scarborough's seafront and sent sandstone from Golden Bank Quarry as far afield as Egypt. Situated on Horsforth Beck (Oil Mill Beck) were mills serving the textile trade.
