(10356) Rudolfsteiner Main-belt Asteroid
Discovered on 15 September 1993 by E. W. Elst at La Silla.
Rudolf Steiner (1861-1925) was the editor of the scientific works of Wolfgang Goethe, and this inspired him to write his well-known work Die Philosophie der Freiheit (1894). In 1912 he founded the Anthroposophical Society upon the belief that there is a spiritual perception independent of the senses.Naming citation (20000320/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
