Ivan Pavlov

This is a tricky blog post because everyone has some knowledge of Ivan Pavlov. In the spirit of Bear in a Hat, though, I wanted to restate that he was Russian and successful. He was the psychologist/physiologist who worked with animals to discover "conditioning". Animals would be presented with a stimulus that they naturally responded to and a stimulus that did nothing for them. Eventually the stimulus that originally did nothing produced the same response as the stimulus with the automatic natural response. Pavlov also did some early work with the digestive system. He won a Nobel Prize in Physiology and is a figurehead for modern psychology. Also, he has a killer moustache.
