Claude Bernard was a French physiologist. Historian I. Bernard Cohen of Harvard University called Bernard "one of the greatest of all men of science". Among many other accomplishments, he was one of the first to suggest the use of a blinded experiment to ensure the objectivity of scientific observations. He originated the term milieu intérieur, and the associated concept of homeostasis (the latter term being coined by Walter Cannon).
