Life

Karl Rohn's grave at the Südfriedhof in Leipzig

Karl Rohn studied in Darmstadt , Leipzig and Munich , a. a. with Alexander von Brill , who led him from his initial engineering studies to mathematics. In 1878 he received his doctorate from Felix Klein in Munich. In 1879 he completed his habilitation in Leipzig. The subject of the doctorate and habilitation was the 4th order Kummer surface and its connection with hyperelliptic functions (with Riemann surfaces of gender 2). In doing so, he solved a research topic that was topical at the time, which Klein himself, Arthur Cayley and Heinrich Weber had also tried to address . In 1884 he became an associate professor at theUniversity of Leipzig and a year later at the Technical University of Dresden , where he became professor for descriptive geometry in 1887. In 1904 he became a professor in Leipzig.

In 1920 he died of a stroke.

In addition to his work on the Kummer surface and other algebraic surfaces , he also examined algebraic space curves and completed the classification work of Georges Halphen and Max Noether . He also made an elliptical compass .

In 1913 he was President of the German Mathematicians Association .
