This photograph shows Ivan Pavlov walking down the stairs. He is carrying his hat in one hand and a cane on the other side. The picture is part of the Peter V. Karpovich Papers in an unbound scrapbook. Pavlov was a Russian physiologist known primarily for his classical conditioning. He enrolled in the physics and mathematics faculty at the University of Saint Petersburg in 1870 to take the course in natural science. He won the Nobel Prize for Physiology or Medicine in 1904. He is most famous for the "conditioned reflex," in which he examined the rates of salivation among dogs. He learned that dogs would salivate when food was presented and a metronome sound was made. The dog later came to associate the metronome sound with the presentation of food. The image is not dated, but most likely was taken sometime in the late 1920s or early 1930s during a visit to the United States.
