Bernoulli in the Academy of the Sciences of Paris, in 1760, supporting inoculation as a preventive system against the smallpox. From the life table of Halley, and proposing a mathematical model of behavior of the disease, Bernoulli presents another one for a free population of smallpox and does a comparison between them and between their life expectancies. In this article we analyze and value the content of this memory using, in addition, a more ordinary and nearby language.8 p.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/SmallpoxInoculationLife TableHistory of the Probability and Statistics18th centuryinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess
