Ivan Pavlov

(1849 - 1936)

Ivan Pavlov was a Russian physiologist whose research on the physiology of digestion led to the development of the first experimental model of learning, Classical Conditioning. Most of his research was gathered studying salivating dogs..

Pavlov was born on September 14, 1849, at Ryazan, Russia. Because he was born into a large family, poverty was always an issue. His father, Peter Dmitrievich Pavlov, was the village priest and young Ivan tended to the church property. Pavlov inherited many of his father's characteristics including a strong will to succeed.

The oldest sibbling, Ivan Pavlov was also among the healthiest. He began school at the Ryazan Ecclesiastical High School. Pavlov and his brothers eventually entered the Ryazan Ecclesiastical Seminary. At the Seminary, he planned to pursue a career in theology. However, after being introduced to the works of Charles Darwin and Ivan Sechenov, Pavlov decided to transfer to the University of St. Petersburg to gain knowledge about natural science. There, Pavlov gained great respect for a professor of physiology, Cyon. Due to Cyon's enthusiasm for physiology, he decided to become a physiologist during his third year. At that point, Pavlov started work as an assistant in a laboratory in which he earned 50 rubles a month.

Eventually, Pavlov's research on the physiology of digestion would earn him the Nobel Prize. As a skilled surgeon, he was able to implant small stomach pouches in dogs to measure the secretion of gastric juices produced when the dogs began to eat. With the help of his assistants, he was able to condition the dogs to salivate at the click of a metronome. As his work progressed, Pavlov established the basis for conditioned reflexes and the field of classical conditioning.
