Georg Hermann Quincke (born November 19, 1834 in Frankfurt (Oder) , †  January 13, 1924 in Heidelberg ) was a German physicist .

Life

Georg Hermann Quincke was a son of the secret medical councilor Hermann Quincke (1808-1891) in Berlin, his younger brother Heinrich Irenaeus Quincke (1842-1922) was a famous internist at the time . Georg Hermann Quincke's son Friedrich Quincke (1865–1934) became a chemist and also a university professor.

Quincke studied physics , chemistry and mathematics in Königsberg , Heidelberg and Berlin and received his doctorate there in 1858 on capillary phenomena in mercury . In 1859 he completed his habilitation and became a private lecturer . In 1863 he married Rebecca Riess (1836–1924), the daughter of the physicist Peter Theophil Riess . In 1865 the Berlin University appointed him extraordinary professor of physics; He had other teaching assignments at the trade academy (1860-1872) and the building academy (1862-1865). In 1872 Quincke went to the University of Würzburg as a full professor and finally returned to Heidelberg University in 1875 as the successor to Gustav Kirchhoff , where he retired in 1907 .

In his scientific work, Quincke was particularly concerned with capillarity , acoustics , optics , electricity ( Quincke rotation ) and magnetism . He discovered colloidal liquids and studied their electrical properties and also did research on molecular forces . In 1866 Quincke constructed Quincke's interference tube, named after him, for measuring acoustic wavelengths . His students include Albert A. Michelson , Ferdinand Braun and Philipp Lenard . Quincke was a member of the Academy of Sciences in Göttingen (1866), the Bavarian Academy of Sciences (1873), the Royal Prussian Academy of Sciences (1879), the Royal Society London (1879), the Royal Academy of Sciences and Fine Arts of Belgium (1895), the Heidelberg Academy of Sciences (1909), the Uppsala Academy and, since 1889, the Royal Society of Edinburgh . In 1897 he received the Cothenius Medal of the Leopoldina.

A street in the Neuenheim district of Heidelberg , a street in the Markendorf district of Frankfurt and a street in Kiel bear his name.
