11900 Spinoy           Discovered 1991 June 6 by E. W. Elst at the European Southern Observatory.
Constant Spinoy (1924-1997) was a famous Belgian artist and engraver who specialised in the design of postage stamps, of which he engraved more than 100. These include Vielsalm, Towers of Ghent and Double astrograph at the Royal Observatory of Uccle. In 1977 he was honored with the Prize of Europe for his Jeugdfilatelie.
