The younger brother of the WM minister Thomas Jackson became a leading advocate of WM involvement in popular education. The WM Conference of 1833 considered proposals for week-day schools in association with local churches, and in 1836 Jackson with two others was asked to report on both Sunday and day school work. Their findings led to the formation of the WM Education Committee in 1839. He was President of the 1847 Conference and house governor of Richmond College, 1848-1855. In the Church controversies of his day he was an anti-reformist. He retired to Newcastle upon Tyne in 1855 and died there on 4 August 1861.
