Solomon Eliot Asch (September 14th, 1907 – February 20th, 1996) was a Jewish psychologist most known for his conformity experiments, in which he demonstrated the influence of group pressure on opinions. Asch was born in Warsaw, Poland to a Jewish family. He grew up in a small town, Łowicz, Poland. In 1920 at the age of 13 he emigrated with his family to the United States. He pursued his graduate degree at Columbia University and became very much interested in Gestalt psychology after meeting and working closely with his adviser there Max Wertheimer, one of the founders of Gestalt. While Asch is most well-known for his conformity experiments and he is believed to have examined to what extent social forces alter people’s opinions and which aspect of group influence is most important-the size of the majority or the unanimity? His findings have come under criticism to the marked theatrics of his most famed experiment questioning the reality of test conditions. Asch was Stanley Milgram’s advisor at Princeton University, and Milgram completed his dissertation on national differences under conformity under Asch.
