– 24 September 1939, Darmstadt) was a German mathematician.
Education and career
After secondary education at Ludwig Georgs Gymnasium in Darmstadt, Dingeldey studied at the universities of Giessen, Leipzig and Munich.
From 1886 to 1892 he worked as a teacher in Darmstadt and
Groß-Gerau. In 1885 Dingeldey received his PhD (Promotierung), with primary supervisor
Felix Klein and co-supervisor
Carl Neumann
Carl Gottfried Neumann (also Karl; 7 May 1832 – 27 March 1925) was a German mathematician.
Biography
Neumann was born in Königsberg, Prussia, as the son of the mineralogist, physicist and mathematician Franz Ernst Neumann (1798–1895), who w ...

University of Leipzig with thesis ''Über die Erzeugung von Curven vierter Ordnung durch Bewegungsmechanismen''. In 1889 he completed his
habilitation
Habilitation is the highest university degree, or the procedure by which it is achieved, in many European countries. The candidate fulfills a university's set criteria of excellence in research, teaching and further education, usually including a ...
at the
TH Darmstadt with a habilitation thesis on knot theory entitled ''Über einen neuen topologischen Process und die Entstehungsbedingungen einfacher Verbindungen und Knoten in gewissen geschlossenen Flächen''. His research followed the work of the Viennese mathematician Oskar Simony. (In 1890 Dingeldey had a pamphlet published with a brief history of topology and basic results on knot theory obtained by various mathematicians.) In 1894 he was elected a member of the
Deutsche Akademie der Naturforscher Leopoldina and was appointed a professor ordinarius of mathematics at the TH Darmstadt. There he was from 1903 to 1905 and again in 1919–1920 the rector and in 1932 retired as professor emeritus.
Dingeldey edited the newer editions of the German language translations of
George Salmon's textbook on conics (updating earlier editions by
Wilhelm Fiedler
Otto Wilhelm Fiedler (3 April 1832 in Chemnitz – 19 November 1912 in Zurich) was a German-Swiss mathematician, known for his textbooks of geometry and his contributions to descriptive geometry.
