14815 Rutberg           Discovered 1981 Oct. 7 by T. M. Smirnova at the Crimean Astrophysical Observatory.
Filipp Grigor'evich Rutberg (b. 1931), a prominent expert in electrophysics, is director of the Institute of Problems of Electrophysics in St. Petersburg. He is widely known for investigations of powerful discharges in dense gas media, non-equilibrium processes in plasma streams and for the design of new electrophysical equipment.
