(10542) Ruckers Main-belt Asteroid
Discovered on 2 February 1992 by E. W. Elst at La Silla.
Hans Ruckers (1555-1623) was the most famous of all harpsichord makers and founder of a dynasty of Flemish instrument makers. His earliest (1581) known instrument is a virginal with two independent keyboards, now in New York City. These instruments were so prized that they were often rebuilt, enlarged and copied.Naming citation (20000320/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
