Max Le Blanc
Max Julius Louis Le Blanc (born May 26, 1865 in Barten (East Prussia) , † July 31, 1943 in Leipzig ) was a German electrochemist .
Life
Le Blanc was born the son of the secret building officer Louis Le Blanc and his wife Marie Kickton . In 1883 he passed the final examination at the grammar school in Rastenburg . From 1883 to 1886 he studied chemistry at the universities in Tübingen, Munich and Berlin. He did his doctorate with A. W. Hofmann in Berlin and later worked as an assistant to Wilhelm Ostwald in Leipzig (habilitation: 1891, professorship: 1895), where he also held lectures until the summer semester of 1896. In the same year, however, Le Blanc switched to the electrochemical department of the Hoechst paintworks in Frankfurt am Main, which was being set up. In 1901 he received a call to the new chair for physical and electrochemistry at the Technical University of Karlsruhe . In 1906 he moved to the University of Leipzig , where he worked until 1933 and was its rector from 1925–1926. He was mainly concerned with rubber research and later with the conductivity of metal oxides. In 1925 he was elected a member of the Leopoldina . Since 1907 he was a full member of the Saxon Academy of Sciences . In 1937 he received the Cothenius Medal of the Leopoldina.
After the transfer of power , Le Blanc signed on November 11, 1933 the professors' commitment to Adolf Hitler and the National Socialist state at German universities and colleges .
In Leipzig, Le Blanc had recognized that the decomposition voltage has a characteristic value for every ion. Le Blanc and Kiliani recognized that the voltage applied during electrolysis can be used for the selective deposition of individual metals during electrolysis ( electrogravimetry ). Le Blanc also developed the hydrogen electrode for pH measurement, acid-stable diaphragms, a capillary for measuring the electrode potentials and a recording method for alternating current ( oscilloscope ).
