Walter Bradford Cannon
Walter Bradford Cannon[edit | edit source]
Walter 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 is best known for his work on the "fight or flight" response and his contributions to the field of homeostasis.
Early Life and Education[edit | edit source]
Cannon was born in Prairie du Chien, Wisconsin, and grew up in Milwaukee. He attended Harvard University, where he studied under the renowned physiologist Henry Pickering Bowditch. Cannon graduated from Harvard in 1896 and continued his studies at Harvard Medical School, where he earned his medical degree in 1900.
Career and Research[edit | edit source]
Cannon's early research focused on the physiology of digestion, but he soon turned his attention to the autonomic nervous system and the body's response to stress. In 1915, he coined the term "fight or flight response" to describe the body's physiological reaction to perceived threats. This concept became a cornerstone of stress research and is still widely studied today.
Cannon also made significant contributions to the understanding of homeostasis, a term he popularized to describe the body's ability to maintain a stable internal environment despite external changes. His work laid the foundation for modern physiology and influenced many areas of medicine.
Legacy and Honors[edit | edit source]
Cannon's work had a profound impact on the field of physiology and medicine. He was a member of several prestigious organizations, including the National Academy of Sciences and the American Academy of Arts and Sciences. In recognition of his contributions, he received numerous awards and honors throughout his career.
Cannon's legacy continues to influence modern medicine and physiology. His concepts of the "fight or flight" response and homeostasis remain central to our understanding of how the body responds to stress and maintains balance.
