Claude Gaspar Bachet de Méziriac
French mathematician (1581–1638) / From Wikipedia, the free encyclopedia
Claude Gaspar Bachet Sieur de Méziriac[1] (9 October 1581 – 26 February 1638) was a French mathematician and poet born in Bourg-en-Bresse, at that time belonging to Duchy of Savoy.[2] He wrote Problèmes plaisans et délectables qui se font par les nombres,[note 1] Les éléments arithmétiques,[note 2] and a Latin translation of the Arithmetica of Diophantus (the very translation where Fermat wrote a margin note about Fermat's Last Theorem). He also discovered means of solving indeterminate equations using continued fractions, a method of constructing magic squares, and a proof of Bézout's identity.
