Inscription.
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.
 
Erected by Lambeth Council.

Excerpt:
John Venn (9 March 1759 – 1 July 1813) was a priest of the Church of England who was a central figure of the group of religious philanthropists known as the Clapham Sect.

Venn was rector of Little Dunham, Norfolk, from 1783 to 1792, and rector of Holy Trinity Church, Clapham from 1792 until his death. He was one of the founders of the Church Missionary Society in 1797, and was a leading abolitionist and philanthropist. These evangelistic and humanitarian interests brought him into close association with abolitionists such as William Wilberforce and Granville Sharp. He ran the school set up by the Society for the Education of Africans which was set up in Clapham in 1799. He died at Clapham on 1 July 1813. A volume of his sermons was published after his death.

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.
