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.

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.”
