# John Venn : English Mathematician

## John venn

John Venn was a famous english mathematician, logician and philosopher from the 19 th century. He is known worldwide for his venn diagrams.

These diagrams are used in logic, set theory, probability, computer science and statics. Venn developed george boole’s theories in his 1881 symbolic logic. Later then, venn diagrams emerged from it.

## John venn’s life history

Venn was born on 4th august 1834 in Kingston upon hull, yorkshire. Her mother’s name was martha sykes and his father his rev venn. When he was just three years old his mother left him alone in this cruel world.

In 1846 john joined london’s sir roger cholemeley’s school for education. Later, for higher education, he came to cambridge. In 1857 he got his degree in mathematics and became a scholar.

In 1868 he married susanna carnegie edmonstone. From this marriage he got a son john archibald venn who also became a renowned mathematician like his father. A son is like a father.

In 1883 he resigned from the clergy and in the same year he was also selected as a fellow of the royal society. He was awarded Sc.D in 1884. His soul flew to heaven on 4th april 1923.

## Venn diagram

Venn diagram is a diagram which is used to show the logical relations between sets. This diagram is used for teaching sets theory and illustrating simple set relationships between logic, statics, and probability. This diagram used simple curves to represent sets. These curves are either circles or ellipses

## Quotes by john Venn

I began at once somewhat more steady work on the subjects and books which I should have to lecture on. I now first hit upon the diagrammatical devices of representing propositions by inclusive and exclusive circles. Of the device was not new then, but it was so obviously representative of the way in which anyone, who approached the subject from mathematical side, would attempt to visualise the propositions, that it was forced upon me almost at once.”

We endeavour to employ only symmetrical figures, such as should not only be an aid to reasoning though the sense of the sight, but should also be to some extent elegant in themselves.”
