Louis Kollros
Louis Kollros (born May 7, 1878 in La Chaux-de-Fonds , † June 19, 1959 in Zurich ) was a Swiss mathematician. From 1909 to 1948 he was a full professor of geometry at the ETH Zurich .
Kollros, the son of a baker, was a student of mathematics and physics at the Zurich Polytechnic from 1896, where he was a fellow student of Albert Einstein and Marcel Grossmann . After graduating in 1900, he taught at the grammar school in his home town of La Chaux-de-Fonds. 1903/04 he studied in Göttingen with Hermann Minkowski and David Hilbert . From 1904 he was a private lecturer at the University of Neuchâtel . He received his doctorate in 1905 under Minkowski at the University of Zurich ( Un algorithme pour l'approximation simultaneé de deux grandeurs ). At the ETH, where Marcel Grossmann taught in the same area until 1927, he held the chair for descriptive geometry and geometry of the situation in French from 1909.
1940/1941 he was President of the Swiss Mathematical Society and from 1958 its honorary member. He was president of Steiner - Schläfli committees directly (which was entrusted with the publication of their works). In this capacity he was co-editor of Schläfli's collected works.
He wrote biographies of Evariste Galois and Jakob Steiner, which appeared in the supplements on the elements of mathematics ( Birkhäuser Verlag ).
Ferdinand Gonseth is one of his doctoral students .
