HERTZ, herts, Heinbicu (1857-94). A Ger- man physicist, born at llamlmrj;. He studied at lirst to become a civil cnf;im'iT, but forsook this profession for the stmlv of matliomatics anil pure science, which lie pursued at Munich and Berlin, becoming llehuholtz's assistant at the latter university in 1880. In 1883 Hertz be- came privat-docent at Kiel, and two years later was called to the Polytechnic Institute at Karls- ruhe as professor of physics. His earlier experi- ments with electro-majinetic waves were per- formed duriti;.; his occupancy of this professor- ship, and made for Hertz such a reputation that he was in 1889 called to the important chair of physics at Bonn, previously occupied liy t'hiusius. To Hertz is due the realiz;ition and detection of the eleetroinafrnetic waves which Maxwell h.id discovered in his theoretical consiih'ration of the nature of electricity. Hertz found that waves produced by the spark of an electrical machine could be received by a circular loop of wire, and was able to show the reflection, refraction, dif- fraction, and polarization of the waves. The first paper describiufr these wonderful discoveries was published in 1887 and the series continued for several years in JVirdermnnti'.t Annahn. In 1890 was publislied Vehcr die Itrzirhungrn ztri- sclirn Lirlil mid Kleclri'ci Hi t .o his (limimmelle M'erke were published in Leipzig the year after his death.

Baggcsen. . .Tew. early orplianed. after- wards Christianized and brought up in a literary atmosphere for the law. he abandoned this gradually for the drama {Itiichardt and His Famihi. 1827; /,oi-r and I'olicii : Cupid's Strokes of Genius. IS.IO). and for satiric criticism in Baggesen's vein (Letters of a Ghost : Poetic Epis- tles from Paradise. 1830). with cutting attacks on the early work of Hans . derscn. that created a deep impression. Continuing dramatic work. Hertz fell into the romantic movement in Svend Daring's House (18.38). and gained cosmopolitan recognition for King Renin's Daughtir (184.5). a charming bit of Provencal chivalric romance from the last "Court of Love." beautiful even in its translations (Englished by Theodore Mar- tini. . tragedy. Vinon (1848). is also note- worthy. He was also an editor and poet. His Dramas are collected in eighteen volumes (1854- 73), his Poems in four (1851-6-2). HERTZ, .M.RTIN .It LKs (1818-95).
