3 Poisson's contributions
Of all the contributions to the central limit theorem in the 19th century, the
contributions by Siméon Denis Poisson would be the most influential on the
contributions of later authors. Poisson published two articles (1824 and 1829)
where he discussed the CLT. Poisson's idea was that all procedures in the physical
world are governed by distinct mathematical laws. In this spirit, he tried to provide
a more exact mathematical analysis to Laplace's theorem. Poisson's contributions to
the CLT were twofold [Fis]:
