John Venn (4 August 1834 – 4 April 1923) was an English mathematician, logician and philosopher noted for introducing Venn diagrams, which are used in logic, set theory, probability, statistics, and computer science.

Life and Career

John Venn was born on August 4, 1834, in Hull, England. He was a British mathematician and logician, best known for his invention of the Venn diagram, a graphical representation of set intersections. Venn came from an academic family; his father was a mathematician and a priest. He showed an early aptitude for mathematics and went on to study at the University of Cambridge.

Venn’s most significant contribution to mathematics was the creation of the Venn diagram in the 1880s. He developed this visual tool to illustrate relationships between different sets, helping to simplify complex mathematical concepts, especially in the field of set theory and logic.

Aside from his work on diagrams, Venn was a prominent logician and contributed to various fields such as probability, statistics, and the philosophy of science. He also held positions as a lecturer and later as a fellow at Gonville and Caius College, Cambridge.


John Venn passed away on April 4, 1923, in Cambridge, England, at the age of 88.

Award and Legacy

John Venn’s legacy is primarily centered around the enduring concept of the Venn diagram. His creation has become a fundamental tool in fields such as mathematics, logic, statistics, and even computer science. Venn diagrams are widely used to visualize relationships between different sets, aiding in problem-solving and data representation.


Venn’s work also contributed to the development of symbolic logic, which has applications in various academic disciplines and even practical applications in computer programming and artificial intelligence.

While Venn’s work during his lifetime might not have garnered a multitude of awards or honors, his ideas have had a profound and lasting impact on the world of mathematics, logic, and the visualization of complex relationships. His name and his legacy live on through the continued use and study of Venn diagrams and his contributions to the field of mathematics and logic.

On 4 August 2014, Google celebrated John Venn’s 180th Birthday with a doodle.
