Wilhelm Vienna (1911)

Wilhelm "Willy" Carl Werner Otto Fritz Franz Vienna (born January 13, 1864 in Gaffken near Fischhausen in Samland , East Prussia ; † August 30, 1928 in Munich ) was a German physicist. He mainly researched the laws of thermal radiation and received the Nobel Prize in Physics for it in 1911 .

Life

In 1866 Wilhelm Vienna's family moved to Drachenstein near Rastenburg , where his father Carl Vienna had bought an estate . Wilhelm attended the grammar school in Rastenburg from 1879 . He had to drop out of high school due to poor performance, but received private lessons from the teachers. From 1880 to 1882 he attended the old town high school (Königsberg) .

From 1882 he studied physics at the Georg August University in Göttingen and the Friedrich Wilhelms University in Berlin . From 1883 to 1885 he worked at Hermann von Helmholtz's laboratory . 1886 doctorate he became Dr. phil. From 1889 he was assistant to von Helmholtz at the Physikalisch-Technische Reichsanstalt . He completed his habilitation in Berlin in 1892.

Since 1896 private lecturer with Adolf Wüllner at the RWTH Aachen , in 1899 he was appointed to its chair by the Hessian Ludwig University of Gießen ; but he was appointed on February 15, 1900, on April 1, 1900 at the Julius Maximilians University of Würzburg, succeeding Wilhelm Conrad Röntgen at the Physics Institute of the Philosophical Faculty II, where he became friends with Maximilian von Frey . In 1913/14, Vienna was rector of the University of Würzburg , where he also belonged to the Senate around 1916 and, as a nationally-minded professor, supported a German Völkischer Verband ( Association of German Völkischer Bünde ) founded on July 30, 1919 . At the end of 1919, Vienna went to the Ludwig Maximilians University of Munich , where in 1920 he again succeeded Röntgen as a university professor.

Vienna was very active in scientific committees. In 1910 he was chairman of the Society of German Natural Scientists and Doctors , 1920–1922 chairman of the German Physical Society . During the First World War he was involved in a leading position together with other conservative scientists for the interests of the German Reich and to suppress, in particular, the English influence on German science. In the following, however, he distanced himself from the more radical views of his comrade-in-arms, Philipp Lenard , which later led to the propagation of " German Physics ". In 1918 he proposed Albert Einstein and Hendrik Antoon Lorentz for the Nobel Prize in Physics.

Vienna died in 1928 at the age of 64. He was buried in the Munich forest cemetery. His cousin Max Wien was one of the pioneers of high frequency technology . Wilhelm Wien's son Karl Wien became known as an extreme mountaineer .

research

Vienna developed the Vienna Displacement Law in 1893/94 , and the Vienna Radiation Law from 1894 to 1896 to describe the thermal radiation emitted by a black body as a function of the wavelength . From 1898, Vienna developed the basics of mass spectroscopy while working on canal beams and identified a positively charged particle with the mass of the hydrogen atom, the proton. Based on the work of Heaviside and Searle, Vienna took the view in his work from 1900 that all physical processes are electromagnetic in nature and that the mass of a body can be calculated completely from its electromagnetic energy , which is an important step towards the equivalence of mass and Energy was. As a staunch supporter of an electromagnetic worldview, Vienna also dealt intensively with the problems of the ether theories of the time and in 1904 developed differential equations for the electrodynamics of moving bodies . It is therefore one of the forerunners of the special theory of relativity .

In 1911 Vienna received the Nobel Prize in Physics for work on thermal radiation .
