51431 Jayardee           Discovered 2001 Mar. 19 by D. T. Durig at the Cordell-Lorenz Observatory.
James R. Durig (b. 1935), father of the discoverer and for 28 years dean of the University of Missouri at Kansas City, directed the graduate studies of more than 100 students and published almost 1000 articles. His research in infrared, Raman and microwave spectroscopy has greatly supported astronomical spectral interpretations.
