7971 Meckbach           Discovered 1960 Oct. 17 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Named in memory of Wolfgang Meckbach (1919-1998), microwave spectroscopist who emigrated from Germany to Argentina in 1951, where he became the co-founder of the Centro Atómico Bariloche and founder of the Bariloche school of atomic collision physics. In spite of difficult times, he excelled as a teacher and researcher in atomic collision physics using ion penetration through matter. By sad coincidence, the name was proposed just as Meckbach suffered a fatal heart attack while skiing. Name proposed and citation prepared by K.-O. Groeneveld.
