Joseph John Gurney (2 August 1788 – 4 January 1847) was a banker in Norwich, England and a member of the Gurney family of that city. He became an evangelical minister of the Religious Society of Friends (Quakers), whose views and actions led, ultimately, to a schism among American Quakers. Biography Gurney was born at Earlham Hall near Norwich (now part of the University of East Anglia), the tenth child of John Gurney (1749–1809) of Gurney's Bank. He was always called Joseph John. He was the brother of Samuel Gurney, Elizabeth Fry (née Gurney), a prison and social reformer, and Louisa Hoare (née Gurney), a writer on education, and also the brother-in-law – through his sister the campaigner Hannah Buxton – of Thomas Fowell Buxton, who was also an anti-slavery campaigner. He was educated by a private tutor at Oxford, members of non-conformist religious groups being ineligible to matriculate in his day at the English universities. In 1817 Gurney joined his sister Elizabeth Fry in her attempt to end capital punishment and institute improvements in prisons. They talked with several Members of Parliament but had little success. In 1818 Gurney was a recorded Quaker minister. (This meant he was noted as a person gifted by God for preaching and teaching, but Quakers then neither explicitly designated individuals to take substantial roles in their worship, nor financially supported its ministers unless their travels in that role would otherwise have been impractical.) Eventually Robert Peel, the Home Secretary, took an interest in prison reform and introduced the Gaols Act 1823, which called for paying salaries to wardens (rather than their being supported by the prisoners themselves) and putting female warders in charge of female prisoners. It also prohibited the use of irons or manacles. Gurney and Fry visited prisons all over Great Britain to gather evidence of the horrible conditions in them to present to Parliament. They published their findings in a book entitled Prisons in Scotland and the North of England. Gurney campaigned against slavery during trips to North America and the West Indies from 1837-1840. He promoted the Friends' belief in world peace in Ireland, Scotland, the Netherlands, Belgium, Germany, and Denmark. He also continued to promote the abolition of capital punishment. Gurney also advocated total abstinence from alcohol. He wrote a tract on the subject called Water Is Best. While Gurney was preaching in the United States he caused
