Walter B. CannonWalter Bradford Cannon (October 19, 1871 – October 1, 1945) was an American physiologist, professor and chairman of the Department of Physiology at Harvard Medical School. He coined the term fight or flight response, and he expanded on Claude Bernards concept of homeostasis. He popularized his theories in his book The Wisdom of the Body, first published in 1932. A Review of General Psychology survey, published in 2002, ranked Cannon as the 81st most cited scholar of the 20th century in technical psychology journals, introductory psychology textbooks, and survey responses.[2][3] Read More Read Less
