PAVLOV, IVAN PETROVICH

(1849–1936), Russian physiologist and Nobel Prize winner.

Ivan Pavlov was born in Ryazan. His father, a local priest, wanted him to attend the theological seminary, but Pavlov's interest in natural sciences led him to enroll in St. Petersburg University in 1870. In 1883 he completed his doctoral dissertation and in 1890 became professor and head of the physiology division of the St. Petersburg Institute of Experimental Medicine, where he remained until 1925. Pavlov's work on the functioning of the digestive system earned him the Nobel Prize in 1904. His originality lay in his approach to physiology, which considered the coordinated functioning of the organism as a whole, as well as his innovative surgical technique, which allowed him to observe digestion in live animals.

Pavlov's most well known research involved the study of conditioned reflexes. In his famous experiment, he placed a dog in a room free of all distractions. He found that the dog, accustomed to hearing a bell ring when being fed, would eventually salivate at the sound of the bell alone. Pavlov also applied his findings to the human nervous system. His work advanced the understanding of physiology and influenced international developments in medicine, psychology, and pedagogy.

Pavlov did not support the Bolshevik Revolution and in 1920 asked for permission to leave with his family. Vladimir Lenin, aware of the international prestige Pavlov brought to science in the Soviet Union, personally intervened to guarantee the resources for Pavlov to continue his research. In 1935, the International Congress of Physiologists awarded Pavlov the distinction of world senior physiologist. He died of pneumonia in Leningrad at the age of eighty-seven.
