LAGRANGE, Count Joseph Louis,
French mathematician. B. Jan. 25, 1736. Ed. Turin College. Lagrange made such astonishing progress in mathematics that at the age of nineteen he submitted to Euler the solution of the most difficult problems. Eecognized at once as a mathe matical genius, he was appointed professor of mathematics at Turin Artillery School in 1756, won the prize of the Paris Academy of Science in 1764 for research on the libration of the moon, and in 1766 succeeded Euler as Director of the Berlin Academy. He returned to Paris in 1787, and was professor at the Polytechnic School during the Eepublic, and head of the commission which installed the decimal system. Napoleon made him Count and Senator ; and even the Eestoration, which he detested alike on political and Eation- alist grounds, was compelled to respect one of the greatest mathematicians of his time. Lagrange was what we should now call Agnostic. D. Apr. 10, 1813.
LA GRASSERIE, Raoul de, French sociologist. B. June 13, 1839. Ed. Eennes. He practised as a barrister at Eennes, and was appointed judge at Loudeac, and after wards at Eennes.
