François-Edouard-Anatole Lucas (1842-1891) was educated at the Ecole Normale in Amiens and became professor of mathematics at the Lycée Charlemagne in Paris. “In number theory his research interest centered on primes and factorization. He devised what is essentially the modern method of testing the primality of Mersenne’s numbers…The first Mersenne prime discovered in over a century, it is the largest ever to be checked without electronic help. He loved calculating, wrote on the history of mechanical aids to the process, and worked on plans (never realized) for a large-capacity binary-scale computer,,,” (DSB).
