Pioneering French mathematician and physicist known for differential equations.

Chronology: 1781-06-21 – 1840-04-25

Origins & Early Life

Baron Siméon Denis Poisson (, US also ; French: [si.me.ɔ̃ də.ni pwa.sɔ̃]; 21 June 1781 – 25 April 1840) was a French mathematician and physicist who worked on statistics, complex analysis, partial differential equations, the calculus of variations, analytical mechanics, electricity and magnetism, thermodynamics, elasticity, and fluid mechanics. Moreover, he predicted the Arago spot in his attempt to disprove the wave theory of Augustin-Jean Fresnel. While his interpretations of physical phenomena were often proven wrong by later researchers, his contributions to mathematics have stood the test of time. He demonstrated that physical problems could suggest new mathematical ideas.

Pivotal Works & Achievements

== Early life and education == Poisson was born in the small town of Pithiviers, now in Loiret, France, about 50 miles (80 km) south of Paris. His father was Siméon Poisson, a retired soldier in the French Army who had served in the Seven Years' War. In 1798, Poisson, then seventeen years of age, matriculated at the École Polytechnique in Paris after scoring in first place in the highly competitive entrance examination. Even as a first-year student, he immediately began to attract the notice of the professors...
