Edgar Morin (born Edgar Nahoum, 1921-2026) was a French philosopher and sociologist of the theory of information who has been recognised for his work on complexity and "complex thought" (pensée complexe), and for his scholarly contributions to such diverse fields as media studies, politics, sociology, visual anthropology, ecology, education, and systems biology. He held two bachelors, one in history and geography and one in law, and never did a Ph.D.
During his academic career, Morin was primarily associated with the École des hautes études en sciences sociales (EHESS) in Paris. Although less well known in the Anglophone world due to the limited availability of English translations of his over 60 books, Morin is renowned in the French-speaking world, Europe, and Latin America.
