(2565) Grogler Main-belt Asteroid
Discovered on 12 October 1977 by P. Wild at Zimmerwald.
Named in memory of Norbert Grögler (1928-1983), mineralogist and planetologist who made significant contributions in meteorite research and in the analysis of lunar samples. After graduating from the University of Vienna he followed the invitation of F. G. Houtermans to join an interdisciplinary team of space physicists and planetologists at the University of Berne. He developed sophisticated methods for the quantitative separation of minerals from meteorites and lunar samples and made several significant discoveries on the mineralogy and petrography of meteorites and lunar rocks. He also had strong interests in archaeology and made relevant scientific contributions investigating thermoluminescence of ancient pottery.Naming citation (WGSBN Bull. 3, #1, 6), IAU / Minor Planet Center, via NASA/JPL
