Accomplishments of Ivan Pavlov

Ivan Pavlov died at the age of 87 years old, in my opinion he lived a very long life to have had passed at 87. He did accomplish many things by discovering Behaviorism, winning a Nobel Prize in Physiology in 1904 at the age of 55. He also made a very big impact with Psychology figuring out why the dog would salivate when he/she saw food.
