Walther Ludwig (mathematician)

from Wikipedia, the free encyclopedia

Walther Ernst Paul Ludwig (born June 10, 1876 in Breslau ; † December 20, 1946 in Dresden ) was a German mathematician and rector of the Dresden University of Technology .

Life

Walther Ludwig's house

Ludwig came as the son of Robert Ludwig, director of the secondary school in Breslau and doctor of philosophy, and his wife Maria, geb. Börner, born in Breslau. After graduation in Breslau studied Ludwig from 1894 mathematics and physics at the Universities of Breslau, Freiburg, Munich and Göttingen and received his doctorate in 1898 with a thesis on the planes which a given conic similar conic sections cut from a surface II. Degree over at of the University of Wroclaw . He then went to the Technical University of Karlsruhe , where he taught as an assistant from 1902. In Karlsruhe he wrote his habilitation on the subject of projective investigations on the circle relationships of non-Euclidean geometry until 1904 and then worked as a private lecturer. In 1907 he married the teacher and merchant's daughter Martha Magda Maria Faber in Karlsruhe.

In 1907 Ludwig was appointed professor for descriptive geometry at the Technical University of Braunschweig and in 1909 he was appointed professor for descriptive geometry at the Technical University of Dresden. He became the successor of the Swiss mathematician Martin Disteli (1862–1923). In the academic year 1930/1931 Ludwig was the rector of the university. As rector, he campaigned for the political neutrality of the student body, but in 1933 he was one of the professors of the TH Dresden who signed the German professors' commitment to Adolf Hitler . Ludwig held the professorship for descriptive geometry at the TH Dresden until 1943, when the subject was deleted from the curriculum.

In 1946 Ludwig worked again as professor for descriptive geometry at the reopened TH Dresden, but died in December 1946. His last residence was at 4 Godeffroystraße (today Leonhard-Frank-Straße).
