Ten Famous Psychologists and Their Achievements

For better or worse a number of psychologists have gained some notoriety over the years, with a few considered outright famous. Here’s a list of significant psychologists and their major contributions to the field. 


Ivan Pavlov 1849–1936

The man behind Pavlovian conditioning was educated in natural sciences in St Petersburg, Russia. His primary interest was physiology and it was while researching the digestive system in dogs that he made his most famous discovery – he noted that dogs would salivate before the delivery of food. Pavlov rang a bell when feeding the dogs which they soon learnt to associate with food. After some time the dogs salivated in response to the bell alone. Pavlovian conditioning has a number of real-life applications including in the treatment of phobias and for aversion therapy.
