Claude Bernard was a French physiologist whose scientific experiments led to several important discoveries. He is credited with coining the phrase milieu intérieur, which refers to the extracellular fluid (ECF) environment. He also pioneered the use of a blinded experiment to eliminate various experimental biases.

Étienne-Jules Marey was a French scientist, chronophotographer, and physiologist. He is best remembered for his work which played a major role in the development of physical instrumentation, cardiology, cinematography, aviation, and the science of laboratory photography. Étienne-Jules Marey is widely regarded as a pioneer of photography.
Charles Richet was a French physiologist remembered for his pioneering work in immunology. He is acclaimed for his work on anaphylaxis, which earned him the prestigious Nobel Prize in Physiology or Medicine in 1913. He was also interested in the study of the paranormal. A proponent of eugenics, Richet was in charge of the French Eugenics Society for six years.

Jean Léonard Marie Poiseuille was a French physiologist and physicist. He is best remembered for formulating and publishing the Hagen–Poiseuille equation. Jean Léonard Marie Poiseuille came up with the equation after developing an interest in the flow of blood in capillaries and veins.
Roger Guillemin is a French-American neuroscientist. He is best known for his work on neurohormones, which earned him the prestigious Nobel Prize for Medicine in 1977. Guillemin is also the recipient of other prominent awards such as the National Medal of Science, Albert Lasker Award for Basic Medical Research, and Passano Award in Medical Sciences.

Paul Bert was a French physiologist, zoologist, and politician. Referred to as the Father of Aviation Medicine, Bert is best remembered for his 1878 work La Pression barometrique, which explains the physiological effects of air-pressure. Paul Bert is also credited with describing oxygen toxicity for the first time.

François Magendie was a French physiologist and a pioneer of experimental physiology. He is perhaps best remembered as a notorious vivisector who often shocked his contemporaries and general public with live dissections at public lectures. Many scholars and scientists have criticized him for needlessly torturing animals in the name of experiments.

Jean Pierre Flourens was a French physiologist and a pioneer in anesthesia. He is also credited with founding experimental brain science; he performed operations on the brains of living rabbits and pigeons to investigate localisationism. Through his experiments, Jean Pierre Flourens was able to confirm that the main divisions of the brain were responsible for different functions.

Henri Dutrochet was a French physician, physiologist, and botanist. Dutrochet is best remembered for his investigation into osmosis. He is also credited with discovering cells in plants and cell biology. Henri Dutrochet’s works earned him several awards including the Académie Française's prize for experimental physiology.

Pierre Jean Georges Cabanis was a French freemason, physiologist, and materialist philosopher. An early proponent of evolution, Cabanis is credited with influencing the work of French naturalist Jean-Baptiste Lamarck. Pierre Jean Georges Cabanis made a statement on natural selection much before Charles Darwin's theory of evolution.
