15273 Ruhmkorff           Discovered 1991 Apr. 8 by E. W. Elst at the European Southern Observatory.
Heinrich D. Ruhmkorff (1803-1877) was a German researcher who invented the Ruhmkorff coil, used in many physical experiments where high voltages are needed. The coil was applied for energizing discharge tubes, notably for generating x-rays.
