1892 - HERTZ, Heinrich. Untersuchungen Ueber Die Ausbreitung Der Elektrischen Kraft. Leipzig: Johann Ambrosius Barth, 1892. Octavo, contemporary three-quarter dark green pebbled morocco gilt, raised bands, patterned endpapers, marbled boards and edges. $2000.First edition in book form of Hertz's discoveries in wireless telegraphy."Hertz demonstrated what Maxwell had predicted, that electromagnetic waves radiated in space with the speed of light. Hertz determined these waves to be of greater length than light and that they could be reflected, refracted and polarized. This discovery and its demonstration led directly to radio communication, television and radar" (Dibner 71). Hertz's proof that electrical waves can be created and then sent and received through space has been shown to be of profound importance in twentieth-century technology. The experiments were reported periodically from 1887 onwards in the Annalen der Physik und Chemie before being collected, with an additional preface and explanatory notes, in book form. With 40 in-text diagrams. Text in German. PMM 377. Norman 1061.
