Siméon-Denis Poisson was a French mathematician and physicist who made significant contributions to a number of fields, including mathematics, physics, and engineering. Poisson is best known for his work on the theory of probability, which he developed in his 1837 book “Recherches sur la Probabilité des Jugements.”

Poisson was born in 1781 in Pithiviers, France. He attended the Ecole Polytechnique, where he studied mathematics and physics. Poisson graduated from the school in 1800 with a degree in mathematics.

**Poisson also made important contributions to the field of optics**

Poisson made significant contributions to a number of fields, including mathematics, physics, and engineering. In 1809, he published his work on the theory of electricity and magnetism, which showed that charges interact with each other at a distance. Poisson also made important contributions to the field of optics.

Poisson died in 1840 in Sceaux, France. In 1841, he was posthumously awarded the Copley Medal.
