Julius Wellstein (born April 8, 1888 in Weißenburg , † April 11, 1978 in Würzburg ) was a German mathematician.

Wellstein was one of ten children of Garrison Administrative Director Joseph Wellstein. After graduation in 1906 in Saarbrücken , he studied mathematics and natural sciences at the University of Strasbourg , where he was in 1912 when Friedrich Schur Dr. phil. nat. PhD ( on the theory of rigid body friction ). From 1912 he was assistant at the chair for descriptive geometry at the TH Dresden with Walther Ludwig and from 1914 at the TH Karlsruhe. In the First World War he was a volunteer from 1914, served in France and the Ukraine and received the Iron Cross first and second class. From 1919 he was again at the TH Karlsruhe as assistant to Richard Baldus , completed his habilitation in 1923 on differential geometry of isotropic curves, was then a private lecturer at the Technical University of Karlsruhe and in 1925 became an associate professor. The successor to Baldus, for whom he had applied and whose chair he represented for one year, was taken over by Gerhard Haenzel in 1932 .

In 1945 he resumed his professorship in 1948 (from July 1, 1947, initially as acting director of the Mathematical Seminar and Astronomical Institute with observatory). In 1952 he retired at his own request.

His older brother Josef Wellstein was a mathematics professor in Strasbourg ; his son Hartmut Wellstein became professor for didactics of mathematics at the University of Flensburg .
