André-Louis Cholesky

André-Louis Cholesky (October 15, 1875, Montguyon – August 31, 1918, Bagneux) was a French military officer and mathematician, born in Montguyon, France.

His paternal family was descendant from the Cholewski family who emigrated from Poland at the beginning of 19th century. He attended the Lycée in Bordeaux and entered the Ecole polytechnique, where Camille Jordan and Henri Becquerel taught.^[1] He worked in geodesy and map-making, was involved in surveying in Crete and North Africa before World War I. But 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 the French military as engineer 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 in the "Bulletin Géodésique".
