Josef Wellstein

Josef Wellstein (born October 17, 1869 in Wetzlar, Germany, June 24, 1919) was a German mathematician.

Wellstein was one of ten children of the Royal Prussian Garrison Administration Director Joseph Wellstein. He was promoted to Heinrich Weber in 1894 at the University of Strasbourg (Via Lindemann's transmission principle) and was a lecturer there from 1895 onwards. In 1898 he became an extraordinary professor at the University of Gießen and in 1904 at the University of Strasbourg. After Alsace-Lorraine fell again to France after the First World War, he was expelled. He died shortly thereafter in his hometown Wetzlar.

With his teacher Weber, he wrote a multi-volume encyclopaedia of elementary mathematics.

His younger brother Julius Wellstein (1888-1978) was a mathematics professor in Würzburg. Edit source text Biographical entry Edit source text Single-level Edit source text Standard data (person): GND: 117345571 (PICA, AKS) | Wikipedia People Search
