Ernst Pringsheim Sr. (* July 11, 1859 in Breslau , Province of Silesia ; † June 28, 1917 there ) was a German physicist in Berlin and Breslau.
He came from the German-Jewish Pringsheim merchant family from Silesia . He studied at various German universities, a doctorate in 1882 with a thesis on the radiometer Dr. phil. and qualified as professor . From 1896 to 1905 he was a professor at the universities in Berlin, where his collaboration with Otto Lummer began, and from 1905 in Breslau . His specialty was optics .
In 1881 he developed a spectrometer with which wavelengths in the infrared range could be measured correctly for the first time . In 1899 he carried out careful measurements with Otto Lummer with black bodies and published the results. A year later, the results formed the basis for a revolutionary theory by the young German researcher Max Planck . Planck decided not to view the energy of a black body as a continuous quantity. From this he developed his quantum hypothesis .
