Karl Zickler

from Wikipedia, the free encyclopedia

Karl Zickler (born September 18, 1860 in Karlsbad , Bohemia , † August 20, 1933 in Brno ) was a German-Bohemian electrical engineer.

Life

He was the son of Karlsbad master rope maker Josef Zickler and his wife Theresia nee Schneider. From 1877 to 1881 he studied mathematics and physics at the Technical University in Prague . During his studies he became a member of the Hercynia Prague country team . After graduating, he worked for two years at secondary schools in Bielsko and Prague. In 1884 he became the assistant and son-in-law of Adalbert von Waltenhofen at the newly founded electrotechnical institute at the Technical University of Vienna. In 1890 he qualified for electromagnetism and the calculation of dynamos and at the same time became head of the department. In 1895 he became a professor of mechanical engineering in Brno.

In 1898, following Hertz 's observations about ultraviolet rays, he invented a kind of photoelectric telegraphy without wire. Hertz had discovered in 1887 that UV light greatly promoted electrical discharges. If the UV-rich light from a carbon arc lamp was directed at the cathode of a widely spaced spherical capacitor , a spark occurred. Zickler used a carbon arc lamp as a transmitter for his telegraph and a glass pane (UV-impermeable) for signaling. On the receiver, a lens made of rock crystal (UV-permeable) concentrated the UV light on the cathode of a spherical capacitor welded into a tube
