Venn House


John Venn (1759–1813) was a priest of the Church of England and a central figure of the Clapham sect. One of the original founders of the Church Missionary Society in 1797, Venn was a leading abolitionist and philanthropist. John Venn’s preaching greatly influenced Henry Thornton in the formation of the Clapham Sect. Venn’s grandson, also named John, was famous for introducing the Venn diagram.
