## Frénicle de Bessy, Bernard (1602–1675)Bernard Frénicle de Bessy was a French amateur mathematician who extensively researched magic squares; his Des quassez ou tables magiques, published posthumously
in 1693, first identified all 880 magic squares of the fourth order. Frénicle
also corresponded with Descartes, Fermat, Huygens, and Mersenne,
mostly on number theory, the work
for which he is best known. ## Related category• MATHEMATICIANS | |||||
