Mathematician:John Venn

Mathematician
British mathematician, also an ordained priest, who was active particularly in the fields of probability, statistics, set theory and logic.

Best known for his invention of the Venn diagram.

Later in his career he turned his attention to history. Invented a machine for bowling cricket balls, which, by all accounts, was good enough to give the visiting Australian cricket team serious trouble when they visited in $1909$.
