Name: Wilhelm Wien

Date: January 13, 1864

Wilhelm Karl Werner Otto Fritz Franz Wien (Fischhausen, Prussia, January 13, 1864 – August 30, 1928, Munich, Germany) – German physicist, Nobel Prize laureate in Physics "for their discoveries concerning the laws governing thermal radiation" (1911). He derived Wien's first law, and from it the Wien displacement law (1893-1894), and Wien's second law for thermal radiation (1896). Wilhelm Wien proved (1898) that the lightest of the "canal rays" (also called anode rays) are hydrogen ions (now called protons). By acting on moving protons with electric and magnetic fields, Wilhelm Wien measured the ratio of the proton's charge to its mass. Wien's laws are the laws of blackbody radiation (1893–1896). A laboratory at the Physikalisch-Technische Bundesanstalt (Bundesphysik-Technische Institut) in the WISTA technology park in Adlershof, a suburb of Berlin, is named after Wien.
