WALTER CANNON :

Walter Bradford Cannon (1871-1945), American physiologist, known for a series of experimental investigations into the process of digestion, the nervous system, and the body's self-regulating mechanisms.

Cannon was born in Prairie du Chien, Wisconsin. He earned his bachelor's, master's, and medical degrees from Harvard University, where he became a professor of physiology. Cannon served as chairman of Harvard's physiology department from 1906 to 1942.

Cannon began his investigations in 1896, a year after German physicist Wilhelm Conrad Roentgen discovered X rays. Cannon used X rays to observe the process of digestion in laboratory animals. Using an instrument called a fluoroscope, he watched the progress of food and waste through the body. During these experiments, Cannon noticed that when an animal was under stress, its digestive processes halted. This led him to wonder about the body's response to danger, fear, and trauma.

Using mainly surgical and chemical means, Cannon investigated the response of the heart, the sympathetic nervous system, and the adrenal gland to unnatural circumstances.

Cannon also studied the body's self-regulating mechanisms, which tend to maintain what he called homeostasis—that is, a constancy of internal conditions such as temperature, fluid levels, and chemical composition of blood and tissue. Beginning in 1931 Cannon suffered from cancer associated with the X-ray exposures he underwent early in his career. He remained active in national scientific circles, overseeing the organization of research for the effective treatment of shock and blood loss during World War II (1939-1945).
