12150 De Ruyter           Discovered 1971 Mar. 25 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Michiel Adriaenszoon de Ruyter (1607-1676), in Dutch history a famous admiral, played a decisive role in the Anglo-Dutch Wars of the seventeenth century. De Ruyter was of humble origin but much loved by his sailors and soldiers. The name was suggested by C. E. Koppeschaar.
