      • Gustav Robert Kirchhoff (German: [ˈkɪʁçhɔf]; 12 March 1824 – 17 October 1887) was a German physicist and mathematician who contributed to the fundamental understanding of electrical circuits, spectroscopy, and the emission of black-body radiation by heated objects. He coined the term black-body radiation in 1860.

  2. He contributed greatly to the field of spectroscopy by formalizing three laws that describe the spectral composition of light emitted by incandescent objects, building substantially on the discoveries of David Alter and Anders Jonas Ångström.

  3. In [1] Rosenfeld sums up Kirchhoff's contribution:- In a period of expanding scientific horizons, the need soon arises for ordering and logical analysis of new knowledge. Among the leading physicists of the nineteenth century, it was Kirchhoff whose temperament was best suited to this task.

  4. Gustav Kirchhoff was a 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.

  5. Gustav Kirchhoff was a famous German physicist who made many contributions to science, including furthering our understanding of electric circuits and developing the new science of spectroscopy.

  6. Gustav Robert Kirchhoff was a German physicist who made significant contributions to the fundamental understanding of black-body radiation emitted by heated objects, spectroscopy, and electrical circuits.

  7. Born in born Königsberg, Prussia, Gustav Kirchhoff’s most celebrated contributions to physics were in the field of spectroscopy. In collaboration with Robert Bunsen (1811-1899), Kirchhoff founded the (then purely empirical) science of spectroscopy.

  8. May 23, 2018 · Kirchhoff’s major contribution to physics was his experimental discovery and theoretical analysis in 1859 of a fundamental law of electromagnetic radiation: for all material bodies, the ratio of absorptive and emissive power for such radiation is a universal function of wavelength and temperature.
