10655 Pietkeyser           Discovered 1960 Oct. 17 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Dutch navigator Pieter Dirkszoon Keyser (c. 1540-1596) sailed to the East Indies in 1595. He is credited with having invented twelve new constellations in the southern sky, first depicted in 1598 on a globe by Petrus Plancius.
