Max Tolle

Max Tolle (born August 12, 1864 in Halberstadt ; † December 23, 1945 in Mülheim an der Ruhr ) was a German mechanical engineer and engineering scientist.

Life

After graduating from high school in Halberstadt, he studied at the Friedrich-Wilhelms-Universität Berlin (1883/84) and then at the Technical University of Berlin , where he passed his examination as a government building supervisor in 1887. In Berlin he heard from Eugen Netto , Karl Weierstrass , Ernst Eduard Kummer and Gustav Kirchhoff, among others . From 1889 he was assistant for mechanical engineering at the TH Darmstadt and from 1891 teacher at the mechanical engineering school in Cologne . In 1900 he became director of the Technikum in Hildburghausen , where he became a professor in 1901 and, after the Technikum was closed, switched to civil service. After a book published in 1905 on the regulation of machines was recognized, he was able to do his habilitation at the TH Karlsruhe with the thesis Determination of the tension of crooked rods, Calculation of flywheels . He was initially a private lecturer in Karlsruhe, from 1918 an honorary professor, from 1921 a regular associate professor (at the same time he received his doctorate with the thesis New Methods for the Study of Torsional Vibrations ) and from 1923 a full professor. There he was the first professor of technical mechanics. In 1933 he retired. The successors to his chair were Friedrich Tölke and Rudolf Sonntag (1937 to 1960).

In particular, in the 24th edition in 1923, in the chapter Mechanics, he wrote a section on vector calculation ; with their formalism he became known through Rudolf Mehmke (correspondence) and probably through the mechanical engineering professor in Karlsruhe Richard Graßmann (a son of Hermann Graßmann , the founder of vector calculation in Germany), with whom he completed his habilitation.
