12138 Olinwilson           Discovered 1960 Sept. 24 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Olin C. Wilson (1909-1994) was an American spectroscopist who worked on solar and stellar activity cycles. With M. K. V. Bappu he found a method of determining a star's luminosity from the widths of two spectral lines.
