Kirchhoff, Gustav Gustav Kirchhoff (b. March 12, 1824, Knigsberg, Prussia [now Kaliningrad, Russia]d. Oct. 17, 1887, Berlin, Ger.), German physicist who, with the chemist Robert Bunsen, firmly established the theory of spectrum analysis (a technique for chemical analysis by analyzing the light emitted by a heated material), which Kirchhoff applied to determine the composition of the Sun. In 1847 Kirchhoff became Privatdozent (unsalaried lecturer) at the University of Berlin and three years later accepted the post of extraordinary professor of physics at the University of Breslau. In 1854 he was appointed professor of physics at the University of Heidelberg, where he joined forces with Bunsen and founded spectrum analysis. They demonstrated that every element gives off a characteristic coloured light when heated to incandescence. This light, when separated by a prism, has a pattern of individual wavelengths specific for each element. Applying this new research tool, they discovered two new elements, cesium (1860) and rubidium (1861). Kirchhoff went further to apply spectrum analysis to study the composition of the Sun. He found that when light passes through a gas, the gas absorbs those wavelengths that it would emit if heated. He used this principle to explain the numerous dark lines (Fraunhofer lines) in the Sun's spectrum. That discovery marked the beginning of a new era in astronomy.

Now 1843 was the year in which Jacobi became unwell, so it was Neumann who influenced Kirchhoff in a very positive way. Neumann Neumann had become interested in electrical induction. In fact Neumann It was while he was studying with Neumann that Kirchhoff made his first outstanding research contribution which related to electrical currents. Kirchhoff's laws, which he announced in 1845, allowed calculation of currents, voltages and resistances in electrical circuits with multiple loops, extending the work of Ohm . Kirchhoff considered an electrical network consisting of circuits joined at nodes of the network and gave laws which reduce the calculation of the currents in each loop to the solution of algebraic equations. The first law states that the sum of the currents into a given node equals the sum of the currents out of that node. The second law states that the sum of electromotive forces in a loop in the network equals the sum of potential drops, or voltages across each of the resistances, in the loop. Kirchhoff's laws followed from applying Ohm 's law but the way in which he was able to generalise the results showed great mathematical skills. At this stage Kirchhoff was unaware that

Kirchhoff also concluded that dark line spectra were obtained when light was passed through a gas corresponding to the wavelengths of emission lines in incandescent elements. Using the spectroscope, Kirchhoff showed that each element, when heated to incandescence, produced a characteristic pattern of emission lines. This led to the identification of cesium in 1860 (named in Latin for the sky blue color of its emission lines), and rubidium in 1861 (named in Latin for the red color of its emission lines).

Kirchhoff's Law s, announced in 1854, allow calculation of currents, voltages and resistances of electrical circuits extending the work of Ohm. His work on black body radiation was fundamental in the development of quantum theory. His work on spectrum analysis led on to a study of the composition of light from the Sun. Kirchhoff was the first to explain the dark lines in the Sun's spectrum as caused by absorbsion of particular wavelengths as the light passes through a gas. This started a new era in astronomy. In 1875 he was appointed to the chair of mathematical physics at Berlin. Disability meant he had to spend much of his life on crutches or in a wheelchair.

März 1824 wurde der Physiker Gustav Robert Kirchhoff im preußischen Königsberg geboren und starb am 17.Oktober 1887 in Berlin, im Alter von 63 Jahren. Kirchhoff machte eine Lehre bei C. F. Gauß. 1845 stellte er als Student, allgemeiner als Ohm, die Gesetze der Stromverzweigung auf. Diese Gesetze beschreiben das Gleichgewicht in Netzwerken linearer elektrischer Leiter. 1850-1854 führte er eine Professorenstelle in Breslau aus und war ab 1854 Professor in Heidelberg. Dort führte er zusammen mit R. W. Bunsen Untersuchungen zur Emission und Absorption des Lichtes durch. Diese Untersuchungen stellen die Grundlage der Spektralanalyse dar und führten 1859 zur Aufstellung der kirchhoffschen Strahlengesetze. Durch die Spektralanalyse entdeckte er die chemischen Elemente Cäsium und Rubidium. 1875 ging er von Heidelberg nach Berlin, wo er Professor für mathematische Physik bis 1886 war.
