Victor Kommerell (around 1935)

Victor Kommerell (born April 17, 1866 in Tübingen ; † May 29, 1948 there ) was a German mathematician . He was senior real teacher in Calw , Reutlingen , Nürtingen and Tübingen and honorary professor at the University of Tübingen .

Life

Victor Kommerell was the sixth and youngest child of the mathematician Ferdinand Kommerell and his wife, Julie b. Steudel (1850–1886), a daughter of the Esslingen merchant Immanuel Steudel.

After graduating from Tübingen grammar school with the "bankruptcy test" (as Primus), Kommerell was accepted into the Tübingen monastery in 1884 and studied mathematics and natural sciences at the University of Tübingen . At the beginning of his studies he became a member of the Igel student association . Professors Alexander von Brill , Hermann Stahl and Holder were of particular influence on him . With the dissertation “Contributions to Gaussian Area Theory” he acquired the degree “Dr. rer. nat. ”and passed the first official examination in the same year. He then expanded his studies at the Friedrich-Wilhelms-Universität Berlin until 1891 . In 1892 he passed the second service examination and was accepted into the higher education service in Württemberg . On August 19, 1897, he married Anna Beate Metzger (1874–1932) in Urach , a daughter of the Urach pharmacist Gottlob Metzger and his wife Mathilde.

From 1898 to 1900 Kommerell was a senior teacher in Calw, and from 1900 to 1904 in Reutlingen. From 1904 to 1912 he was Rector of the Realprogymnasium Nürtingen, from 1912 to 1924 Rector of the Oberrealschule Reutlingen. From 1924 until his retirement in 1933, he was senior director of the secondary school in Tübingen. During his tenure, as a result of the economic crisis of the 1920s, there was a great rush to universities. The schools preparing for study had more tasks, both in administration and in the implementation of the lessons. Victor Kommerell mastered these tasks so excellently at the secondary school that not only did his reputation as a capable school man grow, but he also became a highly valued advisor for school administration. In 1933 he was retired for reasons of age. During the Second World War , when a shortage of teachers began to appear in schools as a result of drafts, he was employed again as a mathematics teacher at the Tübingen girls' high school .

In addition to the educational work at the schools, Kommerell worked scientifically. He published a number of articles in academic and didactic journals. He also wrote - mostly with his cousin Karl Kommerell - a number of extensive mathematical textbooks. In recognition of his scientific achievements, he was appointed honorary professor at the University of Tübingen in 1930, where he then gave lectures on the history of mathematics , spherical trigonometry and mathematical geography .

In the early 1940s Kommerell lived in Tübingen at Hirschauer Strasse 1, but then moved to Nürtingen at Schellingstrasse 21. However, he died in his hometown of Tübingen, where he had been taken to the medical clinic. The cause of death was urosepsis , caused by bladder cancer with metastases in the bones.

In 1916 he was the editor (under the pseudonym G.-W.) of the original edition of the Tübingen Gôgen jokes (in a field edition during the First World War under the pseudonym Romeo ).
