10356 Rudolfsteiner           Discovered 1993 Sept. 15 by E. W. Elst at the European Southern Observatory.
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.
