7972 Mariotti           Discovered 1971 Mar. 25 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Named in memory of Jean-Marie Mariotti (1955-1998), French astronomer, most recently in Garching at the European Southern Observatory. He led the pioneering project to establish optical interferometry with the new Very Large Telescope as a breakthrough new astronomical instrument for the next century. His interest was in the area of high angular resolution, and he was involved in interferometric projects both on the ground (e.g., FLUOR and VLTI) and in space (DARWIN). He hoped with these techniques to find low-mass companions, and ultimately planets, outside our solar system. He had an extraordinarily effective mix of technical expertise and scientific eagerness. Name proposed and citation prepared by R. Le Poole.
