Jean François Théophile Pépin was a French mathematician and Jesuit, born on 14 May 1826 in Cluses, Haute-Savoie, and died on 3 April 1904 in Lyon. He became a Jesuit in 1846 and taught mathematics at several Jesuit colleges, from 1850 to 1856 and again from 1862 to 1871. He was appointed professor of canon law in 1873 and moved to Rome in 1880. His mathematical work centred on number theory: in 1876 he found a new proof of Fermat's Last Theorem for the exponent 7, and in 1880 he published the first general solution to a problem posed by Frénicle de Bessy. His name survives in computing through Pépin's test, a primality test for Fermat numbers that is still the standard way to decide whether a Fermat number is prime.
