12491 Musschenbroek           Discovered 1997 May 3 by E. W. Elst at the European Southern Observatory.
Petrus van Musschenbroek (1692-1761) was a Dutch experimental scientist who will be always remembered for his invention of the Leiden jar, a capacitor capable of collecting electrostatic electricity. In 1792 he published his treatise on experimental physics, Physicae experimentales.
