Henri Atlan

Henri Atlan (born 27 December 1931) is a French biophysicist and philosopher.

Early life and education Born to a Jewish family in French Algeria, Atlan gained degrees in medicine and biophysics at the University of Paris (now University Paris Diderot). He married Liliane Atlan in 1952; they had two children while living in Paris, Miri in 1953 and Michael in 1956. He then moved to the University of California, Berkeley working on ageing and mutation.

Career and thought Influenced by Heinz von Foerster, Atlan became interested in applying cybernetics and information theory to living organisms, and went to the Weizmann Institute in Rehovot to work under the biophysicist Aharon Katchalsky. In 1972, he returned to Paris; and, in that year, his 1972 work on information theory and self-organising systems, entitled L'organisation biologique et la théorie de l'information, received a wide readership. In this book, he proposed the principle of "complexity from noise" , concept taken up in his following book Entre le cristal et la fumée (1979) and development of 1960 Von Foerster's notion of "order from noise". In Paris, he then taught biophysics at the Hôtel-Dieu and, later, at the Hebrew University of Jerusalem's Hadassah Medical Center.

His participation with Francisco Varela at a conference in Cerisy-la-Salle encouraged interest in cognitive science in France. an organization of leaders with political, scientific, and ethical expertise whose goal is to provide new approaches in overcoming the obstacles in the way of a peaceful, socially just, and an economically sustainable world.
