**Laplace**, a celebrated French mathematician, born at
Beaumont-en-Auge, Normandy; the son of a farmer; after teaching in his
native place went to Paris (1767), where he became professor in the Royal
Military School; becoming member of the Académie des Sciences in 1785, he
attained a position among mathematicians and astronomers almost equal to
Newton's; his “Three Laws” demonstrated the stability of the solar
system; he published many treatises on lunar and planetary problems,
electricity, magnetism, and a Nebula-hypothesis; his “Mécanique Céleste”
is unrivalled in that class of work; surviving the Revolution he became
implicated in politics without success or credit; he received his
marquisate from Louis XVIII. in 1817, when he became President of the
French Academy; “Lagrange (*q.v*.) has proved that on Newton's
theory of gravitation the planetary system would endure for ever;
Laplace, still more cunningly, even guessed that it could not have been
made on any other scheme” (1749-1827).
