Stanley Milgram, American social psychologist (d. 1984)
Stanley Milgram (August 15, 1933 – December 20, 1984) was an American social psychologist, best known for his controversial experiments on obedience conducted in the 1960s during his professorship at Yale.Milgram was influenced by the events of the Holocaust, especially the trial of Adolf Eichmann, in developing the experiment. After earning a PhD in social psychology from Harvard University, he taught at Yale, Harvard, and then for most of his career as a professor at the City University of New York Graduate Center, until his death in 1984.

His small-world experiment, while at Harvard, led researchers to analyze the degree of connectedness, including the six degrees of separation concept. Later in his career, Milgram developed a technique for creating interactive hybrid social agents (called 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 the history of social psychology. A Review of General Psychology survey, published in 2002, ranked Milgram as the 46th-most-cited psychologist of the 20th century.
