 Joseph Louis Lagrange 
  Lagrange did not seek fame and saw no reason to come to Prussia while Euler, who he had much respect for, already had the position of director of mathematics at the Berlin Academy. 
  Lagrange's work, which included subjects such as the calculus of variations, probabilities, the principle of least action, kinetic energy, and propagation of sound, appears in the first three volumes, published in 1759, '62, and '66. 
  In 1764, Lagrange won the prize competition from the Académie des Sciences in Paris on the subject of the libration, or "wobble", of the moon.
