From Wikipedia, the free encyclopedia
Christian Christiansen (born October 9, 1843 in Loenborg, Denmark, died 1917) was a Danish physicist.
Christiansen first taught at the local polytechnical school. In 1886 he was appointed to a chair for physics at the University of Copenhagen.
He mainly studied radiant heat and optical dispersion, discovering the Christiansen effect (Christiansen filter). He found numerous absorption spectra with abnormal dispersion, among them aniline red.
