Just for fun, we have put together a short biography on John Venn, creator of the Venn diagram.

John Venn

John Venn came from a Low Church Evangelical background and when he entered Gonville and Caius College Cambridge in 1853 he had
so slight an acquaintance with books of any kind that he may be said to have begun there his knowledge of literature.
He graduated in 1857, was elected a Fellow in that year and two years later was ordained a priest. For a year he was curate at Mortlake.

In 1862 he returned to Cambridge University as a lecturer in Moral Science, studying and teaching logic and probability theory. He developed Boole's mathematical logic and is best known for his diagrammatic way of representing sets and their unions and intersections.
