12173 Lansbergen           Discovered 1977 Oct. 16 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Philippus Lansbergen (1561-1632), Calvanist minister and active astronomical researcher in Middelburg, The Netherlands, in 1629 wrote the first popular book on astronomy in the Dutch language. The book promoted the Copernican system and became a best seller.
