Birth of Pierre-Simon Laplace

23 March 1749

Pierre-Simon Laplace was born on 23 March 1749 in Beaumont-en-Auge. A French mathematician and astronomer, Laplace worked on celestial mechanics, probability and mathematical physics. His five-volume Celestial Mechanics extended Newton's work and attempted to show that the solar system is stable, and he proposed the nebular hypothesis, in which the sun and planets formed from a rotating cloud of gas. He also developed Bayesian-style probability theory and the Laplace transform. A scientific adviser under Napoleon and briefly minister of the interior, he adapted to political change and was rewarded with titles after the Bourbon restoration.
