John Venn (1834–1923), logician and inventor of the Venn Diagram, was born in Drypool, son of Rev. Henry Venn, Rector of Drypool
John Venn stated in 1876 that "every single thing or event has an indefinite number of properties or attributes observable in it, and might therefore be considered as belonging to an indefinite number of different classes of things", leading to problems with how to assign probabilities to a single case.
