Ludwig von Tetmajer (also: Ludwig von Tetmajer-Przerwa ) (born July 14, 1850 in Krompach , Hungary ; † February 1, 1905 in Vienna ) was a professor at the Zurich Polytechnic (now ETH Zurich ) and is considered a pioneer in materials testing and research and founder of the Federal Materials Testing and Research Institute .

Life

Ludwig was born as the second child of Wladyslaw Tetmajer , director of the Marienthal ironworks in Krompach (now Slovakia), and Luise Elsner . They belonged to the Austro-Swiss Tetmajer line , while his cousins, the writer Kazimierz Przerwa-Tetmajer and the painter Włodzimierz Tetmajer , came from the Polish line. He spent his childhood in the vicinity of the ironworks, which had a decisive influence on him. In 1867 he graduated from secondary school with honors and, after completing a one-year preparatory course, enrolled at the engineering school of the Swiss Federal Polytechnic in Zurich. In 1872, at the age of 22, he graduated as a civil engineer with the best possible result.

First he worked as an intern at the Swiss Northeast Railway . In 1873 he returned to the Eidgenössisches Polytechnikum Zürich as assistant to the professor for statics Carl Culmann and in the same year became a private lecturer for building mechanics.

In the meantime, he completed the one-year voluntary military service in the 66th Austro-Hungarian Infantry Regiment in 1875 . In order to be able to acquire Swiss citizenship, he resigned in 1877 as a first lieutenant in the reserve from the kuk infantry regiment No. 34.

After he became a Swiss citizen in 1877 ( citizenship of Wipkingen ), he married the opera singer Maria Luise Kindermann (born March 3, 1852 , † June 22, 1912 ), daughter of the court opera singer August Kindermann, on October 24, 1877 in Munich . They had the children Elsa (* August 26, 1878 ), August Helmar von Tetmajer (* January 12, 1880 , † July 14, 1946 ), the family chronicler, architect, professor in Pilsen and consul in Lucerne , and Bruno Friedrich (* 17 June 1887 ), chemist. Ludwig was the grandfather of Ludwig von Tetmajer (1907–1972) who was the state archivist in Lucerne.

In 1878 he was appointed associate professor at the Polytechnic. In 1880 Ludwig Tetmajer became the provisional and from February 1, 1881 permanent director of the strength testing institute (today the Federal Materials Testing and Research Institute ) and a few days before that he was a full professor of building mechanics. From now on, Ludwig Tetmajer's work was closely linked to Empa's history .

From 1896 he was president of the newly founded International Association for Material Testing of Technology. In 1901 he moved to the Technical University of Vienna as a professor , giving up his teaching activities at the Polytechnic and the management of the Swiss Federal Institute of Strength. In the academic year 1904/05 he was elected rector of the technical university . He was also a co-founder of the TVFA Vienna .

Grave of Ludwig von Tetmajer

On January 31, 1905, Ludwig Tetmajer collapsed in front of his students as a result of a stroke and died the following night without regaining consciousness. He is buried at the Vienna Central Cemetery (14B / 35).

Services

  • Collaboration on various railway constructions, especially on the Gotthard Railway
  • Development of the Tetmajer equation in 1886 as a supplement to Euler's Knick equation.
  • Investigation of the railway bridge built by Gustave Eiffel and collapsed in 1891 (largest railway disaster in Switzerland to date) in Münchenstein , thereby developing a new dimensioning method. (See also: Railway accident at Münchenstein )
  • Establishment of the strength testing institute, today Empa , as an international center for material testing.
  • Introduction of the doctorate at the Technical University of Vienna and thus qualitative improvement in training.
  • Invention of the Tetmajer sieve, the Tetmajer volumeter and the Tetmajer press.
