Wilhelm Wien was born on 13 January 1864 in Parusnoye. A German physicist, Wien made important discoveries in the study of heat radiation. In 1893 he formulated the displacement law that bears his name, which states that the wavelength at which a black body emits most strongly is inversely proportional to its temperature, and in 1896 proposed a formula for the distribution of the radiation that worked well at short wavelengths. His work paved the way for Max Planck's quantum theory. He was awarded the Nobel Prize in Physics in 1911. He also studied cathode rays and canal rays, and held professorships at Wurzburg and Munich.
