Scientific contribution Lagrange was one of the creators of the calculus of variations, deriving the Euler–Lagrange equations for extrema of functionals. He extended the method to include possible constraints, arriving at the method of Lagrange multipliers.
Joseph-Louis Lagrange, comte de l’Empire was an Italian French mathematician who made great contributions to number theory and to analytic and celestial mechanics.
Lagrange wrote on the death of Lavoisier, “It took only a moment to cause this head to fall and a hundred years will not suffice to produce its like.” In 1797, Lagrange became the Professor of Mathematics at École Normale, where he instigated the concept of the thorough training of teachers.
The "generalized coordinates" of our mechanics of today were conceived and installed by Lagrange, and this was an achievement of unmatchable magnitude. -- Salomon Bochner
