17764 Schatzman           Discovered 1998 Mar. 2 by the OCA-DLR Asteroid Survey at Caussols.
Evry Schatzman (b. 1920) assumed a leading role in the development of theoretical Astrophysics in France. His research interests cover a very wide range, from white dwarfs to the rotation of stars and the acceleration of cosmic rays. He has written many books on astrophysics and on science and society.
