Philipp Lenard - Early Life and Work

Early Life and Work

Philipp Lénárd was born in Bratislava (Pressburg), Kingdom of Hungary (then Czechoslovakia, now: Slovakia), on July 7, 1862, as the son of a wine merchant. Lenard's parents were German-speakers, and the Lenard family had originally come from Tyrol in the 17th century. His father Philipp von Lenardis (1812-1896) was a wine-merchant in Pressburg. His mother was Antoine Baumann (1831-1865). The young Lenard studied at the Royal Hungarian Gymnasium, and as he writes it in his autobiography, this made a big impression on him (especially the personality of his teacher, Virgil Klatt). In 1880 he studied physics and chemistry in Vienna and in Budapest. In 1882 he left Budapest and returned to Pressburg but in 1883 Lenard moved to Heidelberg after his tender for an assistant job in the University of Budapest was refused. In Heidelberg he studied under the illustrious Robert Bunsen, interrupted by one semester in Berlin with Hermann von Helmholtz, and obtained his doctoral degree in 1886. In 1887 he worked again in Budapest under Loránd Eötvös as a demonstrator. After posts at Aachen, Bonn, Breslau, Heidelberg (1896–1898), and Kiel (1898–1907), he returned finally to the University of Heidelberg in 1907 as the head of the Philipp Lenard Institute. In 1905 Philip Lénárd became a member of the Royal Swedish Academy of Sciences and in 1907 of the Hungarian Academy of Sciences.

His early work included studies of phosphorescence and luminescence and the conductivity of flames.

Famous quotes containing the words early, life and/or work:

    Mormon colonization south of this point in early times was characterized as “going over the Rim,” and in colloquial usage the same phrase came to connote violent death.
    State of Utah, U.S. public relief program (1935-1943)

    If we are on the outside, we assume a conspiracy is the perfect working of a scheme. Silent nameless men with unadorned hearts. A conspiracy is everything that ordinary life is not. It’s the inside game, cold, sure, undistracted, forever closed off to us. We are the flawed ones, the innocents, trying to make some rough sense of the daily jostle. Conspirators have a logic and a daring beyond our reach. All conspiracies are the same taut story of men who find coherence in some criminal act.
    Don Delillo (b. 1926)

    ...I still have faith occasionally in the brotherhood of man, and in spite of all the tragedies that have intervened since [1945], believe that sometime, somehow, all the nations of the world can work together for the common good.
    Virginia Crocheron Gildersleeve (1877–1965)
