Stanley Milgram

Stanley Milgram (August 15, 1933 – December 20, 1984) was an American social psychologist, best known for his controversial experiment on obedience conducted in the 1960s during his professorship at Yale. Milgram was influenced by the events of the Holocaust, specifically the trial of Adolf Eichmann, in developing this experiment.
His small-world experiment while at Harvard would lead researchers to analyze the degree of connectedness, most notably the six degrees of separation concept. Later in his career, Milgram developed a technique for creating interactive hybrid social agents (cyranoids), which has since been used to explore aspects of social- and self-perception. He is widely regarded as one of the most important figures in social psychology ever.
