André-Louis Cholesky (15 October 1875, in Montguyon – 31 August 1918, in Bagneux) was a French military officer and mathematician. Cholesky was born in Montguyon, France.
His paternal family was descendant from the Cholewski family who emigrated from Poland during the Great Emigration.
He attended the Lycée in Bordeaux and entered the École Polytechnique, where Camille Jordan and Henri Becquerel taught.
He worked in geodesy and map-making, and was involved in the surveying of Crete and North Africa before World War I.
He is primarily remembered for the development of a matrix decomposition known as the Cholesky decomposition which he used in his surveying work. He served in the French military as an artillery officer and was killed in battle a few months before the end of World War I; his discovery was published posthumously by his fellow officer Commandant Benoît in the Bulletin Géodésique.
