# Mersenne, Marin (1588–1648)

Marin Mersenne was a French monk, philosopher, and mathematician best remembered for his work to find a formulate to generate prime numbers based on what are now known as Mersenne numbers. However, he was not primarily a mathematician; he wrote about music theory and other subjects, edited works of Euclid, Archimedes, and other Greek mathematicians, but most importantly corresponded extensively with mathematicians and other scientists in many countries. At a time before scientific journals existed, Mersenne was at the heart of a network for information exchange.
