You mean that Stanley Milgram?
Stanley Milgram is best remembered for the Obedience to Authority experiments he conducted in which "teachers" are instructed to administer shocks to "learners" who give incorrect answers to questions. Migram found that ordinary and well adjusted people were easily persuaded to administer cruel punishment when told by the experimenters that the experiment must go on. Milgram died in 1984 at the age of 51. He was an imaginative researcher who continually found novel ways of investigating social behavior, including, in addition to the obedience experiments and six degrees, the lost letter technique in which stamped and addressed letters were left on the street in order to learn whether citizens would put them in a mailbox. A site devoted to Milgram can be found here.
The Obedience to Authority experiments became a well known aspect of popular culture, showing up, among other places, in a popular song by Peter Gabriel, We Do What We're Told - Milgram's 37. Interestingly enough, most of the references on the web to Milgram's Six degrees study make no mention of the Obedience study, nor vice versa.
