Évry Schatzman

Évry Léon Schatzman (born September 16, 1920 in Neuilly-sur-Seine, France) is a French astrophysicist. [p. 104, "L'Outil Théorie", Évry Schatzman and Isabelle Souriau, Paris: Eshel, 1992.

Schatzman began his studies at the École Normale Supérieure in November 1939. After the German invasion of France, Schatzman, who was Jewish, fled occupied France, arriving in Lyon in January 1942. He worked there for a year and then moved to Haute-Provence Observatory. He began work at the Centre national de la recherche scientifique (CNRS) in the fall of 1945 and received his doctorate in March 1946. He then worked at Copenhagen Observatory and Princeton University before beginning to teach at the University of Paris in 1949, where he remained for 27 years. During this period Schatzman also taught at the Université Libre de Bruxelles (English: "Free University of Brussels"). Schatzman became an associate professor at the University of Paris in 1954. In 1976 he moved to Nice Observatory, where he eventually became a full-time researcher. Schatzman retired in the fall of 1989.

Schatzman worked on white dwarfs during the 1940s. He realized that the atmospheres of white dwarfs should be gravitationally stratified, with hydrogen on top and heavier elements below, [ [http://adsabs.harvard.edu/abs/1945AnAp....8..143S Théorie du débit d'énergie des naines blanches] , Evry Schatzman, "Annales d'Astrophysique" 8 (January 1945), pp. 143–209.] [http://adsabs.harvard.edu/abs/1990RPPh...53..837K Physics of white dwarf stars] , D. Koester and G. Chanmugam, "Reports on Progress in Physics" 53 (1990), pp. 837–915.] ^{, §5–6} and explained pressure ionization in white dwarf atmospheres. He was one of the proponents of the wave heating theory of the solar corona. [ [http://adsabs.harvard.edu/abs/1981ARA&A..19....7K On the theory of coronal heating mechanisms] , Max Kuperus, James A.

Schatzman wrote the astrophysics textbook "Astrophysique Générale" and contributed greatly to the popularity of astrophysics in France. He received the Holweck award in 1985 and the Gold Medal of the CNRS in 1983. He became a member of the French Academy of Sciences in 1985.
