Radó von Kövesligethy


Radó von Kövesligethy , was a Hungarian physicist, astronomer and geophysicist. The first successful spectral equation of black body radiation was the theory of the continuous spectra of celestial bodies by Rado von Kövesligethy, published 15 years before Planck, in 1885 in Hungarian and in 1890 in German. He derived a spectral equation with the following properties: the spectral distribution of radiation depends only on the temperature, the total irradiated energy is finite, the wavelength of the intensity maximum is inversely proportional to the temperature. Using his spectral equation, he estimated the temperature of several celestial bodies, including the Sun.
He also formulated laws to establish the epicenters of earthquakes.
He was an assistant to Loránd Eötvös.
In 1895, he was elected as a corresponding member of the Hungarian Academy of Sciences, and later as a full member.
His first and most outstanding disciple was the astrophysicist Béla Harkányi.
