Death of Ivan Pavlov

27 February 1936

Ivan Pavlov died on 27 February 1936 in Saint Petersburg, aged 86. A Russian physiologist, Pavlov won the Nobel Prize in Physiology or Medicine in 1904 for his research on the digestive system. While studying digestion in dogs he noticed that the animals began to salivate at stimuli associated with feeding, and he developed this into the study of conditioned reflexes, which became a foundation of behaviorism and learning theory. Although he distrusted the Soviet regime in some respects, he was given generous support for his laboratories. His name has become shorthand in popular culture for automatic responses to learned cues.
