249. JOSEPH LOUIS LAGRANGE. _Astronomer._

[Born at Turin, in Italy, 1736. Died in Paris, 1813. Aged 77.] At the age of 19, was Professor of Mathematics at the College of Turin. Appointed successor to Euler when the latter was removed from Berlin. Subsequently settled in Paris, where he became one of the Directors of the Mint, and Professor in the Polytechnic school. In 1793, when all foreigners were ordered to leave France, he was permitted to remain. His important labours contributed largely to the advancement of mathematics and astronomy, agitating most of the problems which Laplace subsequently treated with such success. Delicate in health, he led a temperate life; and in society he was reserved and contemplative. Neither great fame nor high honour impaired his modesty. One of the Encyclopedists.
