Sigmund Gundelfinger

from Wikipedia, the free encyclopedia

Sigmund Gundelfinger (born February 14, 1846 in Kirchberg an der Jagst , † December 13, 1910 in Darmstadt ) was a German mathematician.

Life

Gundelfinger was born as the son of the Jewish textile merchant Salomo Gundelfinger and his wife Julie born. Simon, moved from Michelbach an der Lücke , was born in Kirchberg in the current house at Poststrasse 30. After attending school in Kirchberg, Ansbach and Stuttgart , he studied law in Tübingen from 1864 and then mathematics and physics in Heidelberg (from 1864), Königsberg (Prussia) (1866) and Gießen . During his studies he became a member of the Germania Gießen fraternity in the winter semester of 1866/67 . In Giessen he studied with Alfred Clebsch and Paul Gordan and was awarded a summa cum laude Dr. phil. doctorate after an oral examination (a written dissertation was not necessary at the time). For the next two years he lived with his parents in Stuttgart, did mathematical studies and worked on his habilitation thesis, with which he obtained his habilitation at the University of Tübingen in 1869 ( on the theory of the simultaneous system of a cubic and a biquadratic binary form ).

In the same year he was one of the founders of the mathematical seminar with Hermann Hankel and a few other colleagues. He was also given permission to teach mathematics as a private lecturer in this seminar (which was part of the university's science faculty). In the summer of 1872 he was entrusted with a teaching position for analytical geometry and algebra and on May 6, 1873 appointed associate professor of mathematics. In 1878 he married Amalie Gunz, daughter of the businessman Leopold Gunz in Augsburg . In the autumn of 1879 he was appointed full professor for analytical geometry, differential and integral calculus at the Technical University in Darmstadt , as the successor to Ludwig Kiepert . From 1887 to 1893 he was dean of the mathematical and natural science school; In 1907 he retired. In 1888 he was elected a member of the Mathematics Section of the Leopoldina .

As a student of Clebsch and Gordan, Gundelfinger dealt primarily with invariant theory and its application to algebraic curves, but also, as a student of Otto Hesse in Heidelberg, with analytical geometry. He edited several books by Hesse. He also published tables of real roots (Teubner-Verlag 1897) and logarithms (nine-digit logarithm tables, Darmstadt 1891, seven-digit tables Leipzig 1900, 1902).

In 1895 he received half of the Steiner Prize of the Prussian Academy of Sciences and in 1897 the gold medal Bene Merenti of the Bavarian Academy of Sciences. Gundelfinger had the title of Privy Councilor.

Gundelfinger's last years were overshadowed by a severe nervous condition that drove him to suicide. His eldest son (1880-1931) became a well-known member of the circle around Stefan George under the name Friedrich Gundolf from 1899 . He received his doctorate in Heidelberg in 1903, where he was appointed associate professor of literary history in 1916 and full professor from 1920.
