In 1835, he founded the first international scientific journal, the Bulletin Astronomique, and later the Bulletin de l'Académie Royale. His work laid the groundwork for modern sociology, criminology, and demography by demonstrating the power of quantitative methods. Quetelet died in 1874, leaving a legacy as a trailblazer in applying mathematics to understand society.
