Gustav Robert Kirchhoff (1824-1887) Físico alemão nascido em Koenigsberg em 1824 e falecido em Berlim em 1887. Os seus trabalhos científicos mais notáveis tiveram lugar no domínio da radiação térmica e da análise espectral, tendo descoberto, em 1861, juntamente com Bunsen , o rubídio e o cério ; no decurso destes trabalhos, apresentou a primeira explicação das riscas de absorção ou riscas de Fraunhofer. Realizou também estudos sobre a teoria dos circuitos eléctricos. Foi professor de Física na Universidade de Heidelberg. Em 1874 passou para a Universidade de Berlim e foi eleito sócio da Academia.

In 1860 Robert Bunsen (1811–1899) and Gustav Kirchhoff (1824–1887) discovered two alkali metals, cesium and rubidium, with the aid of the spectroscope they had invented the year before. These discoveries inaugurated a new era in the means used to find new elements. The first fifty elements discovered—beyond those known since ancient times—were either the products of chemical reactions or were released by electrolysis. From 1860 the search was on for trace elements detectable only with the help of specialized instruments like the spectroscope. Bunsen, the son of a professor of modern languages at Göttingen University, earned his doctorate from that university in 1830. He was then given a three-year travel grant that took him to factories, places of geologic interest, and famous laboratories, including Joseph Louis Gay-Lussac's in Paris. Early in his career he did research in organic chemistry, which cost him the use of his right eye, when an arsenic compound, cacodyl cyanide, exploded. Throughout his career he remained deeply interested in geological topics and once made daring temperature measurements of the water in the geyser tube of Iceland's Great Geyser just before it erupted. Bunsen and Kirchoff, a physicist trained at Königsberg, met and became friends in 1851, when Bunsen spent a year at the University of Breslau, where Kirchoff was also teaching. Bunsen was called to the University of Heidelberg in 1852, and he soon arranged for Kirchoff to teach at Heidelberg as well.

Königsberg, Kirchhoff und der ideale "Schwarze Körper" Der Vater der Spektralanalyse und Wegbereiter der Infrarotthermographie Wolfgang Thüne Kirchhoff war zweimal verheiratet. Im Jahre 1857 heiratete er Clara, die Tochter seines Mathematikprofessors Friedrich Julius Richelot und dessen Frau Adelheid Köhn von Jasky, die bereits 1969 verstarb. Der Ehe entstammte der Sohn Gustav, der später Oberbürgermeister von Insterburg war. In zweiter Ehe (1872) war er mit Luise Brömmel aus Goslar verheiratet, die ihn, an den Rolstuhl gefesselt, bis zu seinem Tod am 17. Oktober 1887 umsorgte. Die zum Teil als Pionierleistungen zu wertenden Arbeiten Kirchhoffs wurden 1891 von Boltzmann gesammelt herausgegeben. Von seinen 4 Bänden Vorlesungen über "Mathematische Physik" gab Kirchhoff selbst nur das "Lehrbuch der Mechanik" 1874 zum Druck. Die anderen Arbeiten wurden nach seinem Tod von Otto Krigar-Menzel, von Max Planck und Wilhelm Wien herausgegeben. Eine besonders schaffensreiche Periode waren die Jahre 1858 bia 1863. Sie beruhte auf engster Zusammenarbeit mit Bunsen und drehte sich vorwiegend um ein Problem, die Emission und Absorption von Strahlung von dichter Materie und Atomen. Ihre Ergebnisse sind als Kirchhoffsche Strahlungsgesetze, als Bunsen-Kirchhoffsche Spektralanalyse und als Kirchhoffsche Analyse der Sonnen- und Sternmaterie weltweit bekannt geworden. Sie vollenden die von Fraunhofer 1816 eingeleitete Erforschung der hellen wie dunklen Linien, der "Fraunhoferschen Linien", im Sonnenspektrum. Bunsen hatte bereits in den 40er Jahren vergeblich versucht, die in dem kontinuierlichen Sonnenspektrum auftretenden dunklen Linien zu erklären. Auch mit Hilfe seines 1857 erfundenen "Bunsenbrenners" gelang es nicht. Erst Kirchhoff gelang die Konstruktion eines 3-Rohr-Spektrometers.

Kirchhoff Gustav Robert Né en 1824 à Königsberg et décédé à Berlin en 1887 Nationalité allemande Physicien Kirchhoff a inventé le spectroscope qu'il a utilisé avec Bunsen pour montrer que chaque élément possède son propre spectre. Il a ainsi fondé l'analyse spectrale. Dans le domaine de l'électricité, il a énoncé les lois générales des courants dérivés. Il a aussi imaginé le concept de "corps noir" qui allait permettre avec les travaux de Planck , d'ouvrir la voie à la mécanique quantique. cliquez sur un des boutons ci-dessus pour visiter l'un de nos menus de recherche
