Henri Tajfel (born Hersz Mordche; 22 June 1919 – 3 May 1982) was a Polish social psychologist, best known for his pioneering work on the cognitive aspects of prejudice and social identity theory, as well as being one of the founders of the European Association of Experimental Social Psychology.
Tajfel grew up in Poland. Because of Polish numerus clausus restrictions on Jews in university education , he left Poland to study chemistry at the Sorbonne in France. At the outbreak of World War II, he volunteered to serve in the French army. A year later, he was taken prisoner-of-war by the Germans. He faced a dilemma: whether or not to admit to the Germans that he was a Polish Jew. He claimed to be a French citizen but did not deny his Jewish identity. He reasoned that if he denied being Jewish and if the Germans found out later that he was Jewish, he would certainly have been killed. In the event, Tajfel survived the war in a series of prisoner-of-war camps.
On his return home he discovered that none of his immediate family, and few of his friends, had survived the Nazi Holocaust. He was to write later about the profound effect that this had on him and how it led to his later work on the psychology of prejudice and intergroup relations.
After the war Tajfel worked for a series of relief organisations including the Œuvre de secours aux enfants (OSE), a Jewish humanitarian organisation. Tajfel's work with OSE involved resettling Jewish children, many of whom were orphans who had lost all their family. Tajfel would often say that his work with OSE was the most important achievement in his life and he kept in touch with many of the children whose lives he helped to rebuild. He also worked for the United Nations International Refugee Organisation.
He was granted French citizenship in 1946. However, he was soon to meet his future wife Anna-Sophie Eber (Ann), who had been born in Germany but had moved to Britain before the Second World War. Henri and Ann set up home in Britain where their two sons, Michael and Paul, were born.

Social identity is the portion of an individual's self-concept derived from perceived membership in a relevant social group. As originally formulated by social psychologists Henri Tajfel and John Turner in the 1970s and the 1980s, social identity theory introduced the concept of a social identity as a way in which to explain intergroup behaviour.
The minimal group paradigm is a method employed in social psychology. Although it may be used for a variety of purposes, it is best known as a method for investigating the minimal conditions required for discrimination to occur between groups. Experiments using this approach have revealed that even arbitrary distinctions between groups, such as preferences for certain paintings, or the color of their shirts, can trigger a tendency to favor one's own group at the expense of others, even when it means sacrificing in-group gain.
Intergroup relations refers to interactions between individuals in different social groups, and to interactions taking place between the groups themselves collectively. It has long been a subject of research in social psychology, political psychology, and organizational behavior. In 1966, Muzafer Sherif proposed a now-widely recognized definition of intergroup relations: Whenever individuals belonging to one group interact, collectively or individually, with another group or its members in terms of their group identification, we have an instance of intergroup behavior.
The feeling of synchrony is fundamental for most social activities and prosocial behaviors. However, little is known about the behavioral correlates of this feeling and its modulation by intergroup differences. We previously showed that the subjective feel ...
