John Venn

John Venn (1834–1923) was an English logician, philosopher, and mathematician best known for his work in mathematical logic and set theory. He is most famous for creating the Venn diagram, a graphical representation used to show the relationships between different sets. Venn diagrams use overlapping circles to represent the sets and their intersections, making them a valuable tool in various fields, including mathematics, statistics, computer science, and logic.
