(Redirected from Gustav Robert Kirchhoff)

Gustav Robert Kirchhoff (12 March 1824 – 17 October 1887) was a German physicist who contributed to the fundamental understanding of electrical circuits, spectroscopy, and radiation by heated objects. He coined the term black body radiation in 1862.[1]

He proposed two sets of independent concepts in both circuit theory and thermal emission. They are all called 'Kirchhoff's laws' after him, as well as a law of thermochemistry. The Bunsen–Kirchhoff Award for spectroscopy is named after him and his colleague, Robert Bunsen. He also discovered rubidium with Bunsen in 1861.
