John Venn
(1834-1923)

Died aged 88

John Venn, FRS, FSA (4 August 1834 – 4 April 1923) was an English mathematician, logician and philosopher noted for introducing Venn diagrams, which are used in logic, set theory, probability, statistics, and computer science. In 1866, Venn published The Logic of Chance, a ground-breaking book which espoused the frequency theory of probability, arguing that probability should be determined by how often something is forecast to occur as opposed to "educated" assumptions. Venn then further developed George Boole's theories in the 1881 work Symbolic Logic, where he highlighted what would become known as Venn diagrams.

The Reverend John Venn (1759 - 1813), after whom this street is named, was the Rector of Clapham from 1792. He was also a leader of the progressive Clapham Sect, a group of evangelical Christians who worshipped at Holy Trinity Church and who campaigned for the abolition of the slave trade amongst many other religious, philanthropic and moral causes. The grandson of Rev John Venn was Dr John Venn (1834 - 1923). He was a logician and philosopher who supported his theories with the aid of diagrams made from overlapping circles. the Venn diagram demonstrates the relationship between different groups. It also neatly represents the collaborative spirit of Lambeth Council, the Venn Street traders, and local residents, who worked together on the Venn Street Improvements of 2011.
