Pierre-Simon de Laplace or Pierre-Simon Laplace, Count Laplace, then 1st Marquis de Laplace, born March 23, 1749 in Beaumont-en-Auge and died March 5, 1827 in Paris, is a mathematician, astronomer, physicist and politician French.

Laplace was one of the main scientists of the Napoleonic period. Indeed, he has made fundamental contributions in different fields of mathematics, astronomy and probability theory. He was one of the most influential scientists of his time, notably through his assertion of determinism. He contributed decisively to the emergence of mathematical astronomy, taking up and extending the work of his predecessors in his Treatise on Celestial Mechanics (1799-1825). This major work, in five volumes, transformed the geometric approach to mechanics developed by Newton into an approach based on mathematical analysis.

In 1799, he was appointed Minister of the Interior under the Consulate. Napoleon I gave him the title of Count of the Empire in 1808. In 1817 he was made a Marquis by Louis XVIII, after the restoration of the Bourbons.
