(1) Born at Turin, January 25, 1736; died in Paris, April 10, 1813. As an Italian by birth, the name might be given as Guiseppe Luigi; but the family was originally French, affiliated to that of Descartes, and Lagrange spent the best years of his life in France. His complete works were published in Paris, 14 vols. (1866-1892), with a biography by Delambre in volume I. See also G. Loria, "G.L. Lagrange nella vita e nelle opere," in the Annali di Matematica pura ed applicata, XX (3), p. ix.
