Louis Denis Jules Gavarret

Who was Louis Denis Jules Gavarret?

Louis Denis Jules Gavarret was a French physician born in Astaffort, Lot-et-Garonne.

He studied at the Ecole Polytechnique in Paris, followed by military service as an artillery officer. In 1833 he resigned his commission and began his studies with Gabriel Andral.

Gavarret is remembered for the systemization and expansion of Pierre Charles Alexandre Louis' statistical methodology in regards to medicine. Pierre Louis' contention was to make medicine an exact science in diagnosis of a medical condition, and also to refute the "inductive approach" that was prevalent at the time. Gavarret was a major proponent of the statistical method. He emphasized that the process would only work under certain conditions, such as the medical cases must be comparable, and there has to exist enough examples to reach an exact conclusion. Gavarett's precision or "confidence rate" was calculated to be 99.5% or a ratio of 212:1. In essence, the two doctors believed that through knowledge of the aggregate patient data, the disease and treatment would be understood.
