Poisson distribution and the development of probability theory: Siméon Denis Poisson

Siméon Denis Poisson (1781-1840) was a famous French mathematician, physicist and founder of statistical theory. He established the Poisson distribution model through the criminal trial cases and solved many random phenomena in natural science and social science. He also introduced birth statistics, Poisson's inference theory, Laplace's theorem and error theory, law of large numbers and judgment probability and other related theories. Poisson promoted the development of probability theory in the 19th century and opened up a new trend of physics from experimental research to theoretical research.
