John Venn

Venn diagrams were introduced in 1880 by
John Venn, "M.A. Fellow and Lecturer in
Moral Science, Caius College, Cambridge University",
in a paper entitled
*On the Diagrammatic and Mechanical
Representation of Propositions and Reasonings
* which appeared in the Philosophical Magazine and Journal
of Science S. 5. Vol. 9. No. 59. July 1880,
[Ve80].

John Venn was born August 4, 1834 in Hull, Yorkshire, England and died April 4, 1923 in Cambridge, England. He came from a Low Church Evangelical background and in 1853 entered Gonville and Caius College of Cambridge University in 1853. In 1857 he was named a Fellow of the college. He was ordained a priest 1859 and for a year was curate at Mortlake.

He published his first book *Symbolic Logic* in 1881 and
*The Principles of Empirical Logic* in 1889.
In 1883 John Venn was elected a Fellow of the Royal Society.

He wrote a history of his college, *The Biographical History
of Gonville and Caius College 1349-1897* (1897),
and then began to compile a history of Cambridge University.
He completed three volumes, and others continue the work,
with the eighth volume now in preparation.

The use of diagrams in formal logic is not an easy history to trace, but it is certain that the diagrams that are popularly associated with Venn, in fact, originated much earlier. For more of the history of Venn diagrams the reader is referred to Baron [Ba] and Hamburger and Pippert [HP].
