Gustav Robert Kirchhoff (March 12, 1824 - October 17, 1887), physicist who is well known for his electrical rules, Kirchhoff's voltage law and Kirchhoff's current law, which are fundamental to circuit analysis in electrical engineering. He was born in Königsberg, Prussia (now Kaliningrad, Russia) and died in Berlin, Germany.

2 Kirchhoff's Radiation Laws
Kirchhoff's Law of Radiation
Kirchhoff formulated the following law in 1859, followed by a proof in 1861.
- The rate of emission of energy by a body is equal to the rate at which the body absorbs energy (both emission and absorption being in a given direction at a given wavelength).
