Gustav Kirchoff

1824-1887

Gustav Robert Kirchhoff 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 sets of independent concepts in both circuit theory and thermal emission are named "Kirchhoff's laws" after him.

The Bunsen-Kirchhoff Award for spectroscopy is named after him and his colleague, Robert Bunsen.
