Gustav 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 the emission of black-body radiation by heated objects.He coined the term "black body" radiation in 1862, and two different sets of concepts (one in circuit theory, and one in thermodynamics) are named "Kirchhoff's laws" after him; there is also a Kirchhoff's Law in thermochemistry.
