Serge Moscovici is a French social psychologist whose research on psychoanalysis and social influence remains enduringly important. Born in Romania to Jewish parents, he was involved in communist politics as a young man but, disillusioned with the post-war Soviet occupation, he emigrated to France in 1947. He is famous for his work on crowd psychology and minority influence, which corrected previous researchers’ emphasis on conformism by showing how the consistent expression of minority sentiment can influence the majority and bring about social change. He also developed an influential theory of social representations, and his study of the ways in which knowledge of psychoanalysis was transformed as it was reconstructed by different social groups in French society remains a classic. Polity has published this book, Psychoanalysis: Its Image and Its Public, in addition to The Making of Modern Social Psychology and The Invention of Society.
