Something wrong?A 17th-century priest who never stopped asking questions about numbers and strings. Mersenne primes - those clean powers of two, minus one - carry his name because he catalogued which ones might actually be prime, a puzzle still chased today.

About this person
Born in France in 1588, Mersenne took holy orders in the Minim religious order and spent his life weaving together theology, mathematics, and natural philosophy. He worked out the laws governing vibrating strings - the math behind every guitar and piano note - and published Harmonie universelle, the text that earned him the title "father of acoustics". But his wider gift was connection: from his cell in Paris, he maintained correspondence across Europe, linking Descartes, Fermat, Galileo, and Pascal, brokering ideas when journals didn't yet exist. He died in 1648, a week shy of his sixtieth birthday, having served as the continent's indispensable switchboard.
