10961 Buysballot           Discovered 1960 Sept. 24 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Dutch scientist Christophorus H. D. Buys Ballot (1817-1890) created Buys Ballot's law describing the turning of the winds in northern and southern hemispheres. He founded the Astronomical Institute at the University of Utrecht (Sonnenborgh) in 1853 and the Royal Netherlands Meteorological Institute in 1854.
