Marin Mersenne, OM was a French polymath whose works touched a wide variety of fields. He is perhaps best known today among mathematicians for Mersenne prime numbers, those written in the form Mn = 2n − 1 for some integer n. He also developed Mersenne's laws, which describe the harmonics of a vibrating string, and his seminal work on music theory, Harmonie universelle, for which he is referred to as the "father of acoustics". Mersenne, an ordained Catholic priest, had many contacts in the scientific world and has been called "the center of the world of science and mathematics during the first half of the 1600s" and, because of his ability to make connections between people and ideas, "the post-box of Europe". He was also a member of the ascetical Minim religious order and wrote and lectured on theology and philosophy.

The Minims, officially known as the Order of Minims, and known in German-speaking countries as the Paulaner Order, are a Roman Catholic religious order of friars founded by Francis of Paola in fifteenth-century Italy. The order soon spread to France, Germany and Spain, and continues to exist today.
