 Walter Bradford Cannon

Walter Bradford Cannon (1871–1945) was an American physiologist and professor at Harvard Medical School. He is best known for his pioneering work in the study of the sympathetic nervous system and for his research on homeostasis, which is the body's ability to maintain stable internal conditions despite external changes. Cannon introduced the term "homeostasis" in the early 20th century to describe the processes by which various physiological systems are regulated to maintain equilibrium.
