116446 McDermid           Discovered 2004 Jan. 5 by J. W. Young at Table Mountain Observatory.
Stuart McDermid (b. 1952), a senior research scientist in JPL's Science Division, has developed Table Mountain's Lidar facility to establish long-term records of atmospheric composition. He has made significant contributions to our understanding of natural and human impacts on the stratospheric ozone layer.
