ABSTRACT
Heinrich Hertz, after completing highly-regarded research of outstanding quality, while still in the prime of life, actively engaged in demanding work and with great plans for the future, has fallen victim to an insidious disease. The Physical Society does not merely mourn the death of a scientist; it has shared with him a more intimate, personal relationship. Very early on he directed his attention—as indeed every independent and ambitious young man in the exact sciences does—to the deepest problems of astronomy, physics and mathematics, in which he naturally left his fellow students far behind. Hertz succeeded in proving, by measuring the induced current which flowed in two thick parallel wires, first in the direction of the primary current, and then in the opposite direction, that the kinetic energy of the induced electricity.
