Bernard Frénicle de Bessy was a French mathematician born in Paris around 1604 who died in 1674 and wrote numerous papers, mainly on number theory and combinatorics. He is best remembered for Des quarrez ou tables magiques, a treatise on magic squares published after his death in 1693, in which he described all 880 essentially different normal magic squares of order 4; the Frénicle standard form of a magic square is named after him. He solved many problems set by Fermat, found the cube property of the number 1729 later called a taxicab number, and wrote a treatise on right-angled triangles in whole numbers, published in 1676. A member of the French Academy of Sciences, he corresponded with Mersenne and Pascal and was particularly close to Fermat, Descartes and Wallis. In 1661 he set Wallis a problem in integers whose solution came only in 1880, from Théophile Pépin.
