Gustav Jäger (physicist)
Gustav Jäger (born April 6, 1865 in Schönbach bei Asch , † January 21, 1938 in Vienna ) was an Austrian physicist.
Life
Jäger was the second youngest of the 13 children of the Unterschönbach dye works owner Georg Jäger and his wife Johanna. He grew up in the Villa Jäger . After attending primary and secondary school in Asch , Jäger switched to the grammar school in Eger in 1879 , where he passed his Matura. He then studied physics at the University of Vienna under Joseph Loschmidt , Victor von Lang and Josef Stefan and received his doctorate in 1888. From 1891 he was a private lecturer at the Institute for Theoretical Physics and assistant to Stefan and, after his death, to Ludwig Boltzmann . From 1897 he was an associate professor for theoretical physics at the University of Vienna and from 1905 he was a full professor at the Technical University of Vienna , where he was rector in 1915/16. From 1918 he was head of the institute for theoretical physics at the University of Vienna and from 1920 head of the 2nd Physics Institute of the university. In 1934 he retired.
Jäger worked for Boltzmann and, among other things, dealt with his kinetic gas theory and its applications, for example for the question of the internal friction of compressed gases in long pipelines in the chemical industry. He also dealt with room acoustics (Jäger-Sabine formulas or Sabine-Frankel-Jäger theory, applied among other things for reverberation in concert halls), sound propagation and the flow resistance of bodies in liquids and gases, with light pressure, stereoscopes and chemical processes in photography.
In 1903 he refuted an objection made by the physicist Hermann von Helmholtz to powered flight and thus contributed to making it possible in the eyes of physicists. He also supported the Austrian aircraft pioneer Wilhelm Kress (as did his teacher Boltzmann).
In the Göschen Collection he published a textbook in several volumes on theoretical physics.
He was a member of the Vienna Academy of Sciences , since 1935 he was a member of the Leopoldina . From 1930 to 1934 he was President of the Weights and Measures Commission.
He was buried in an honorary grave at Hietzingen cemetery .
